When planning a trip to the Galapagos Islands it is important to pick the time of year that will be best for you. While every month of the year offers distinct benefits and opportunities, finding the month with the wildlife you want to see and the weather you would prefer to experience is important for many visitors. There is no one “perfect” month to visit – it really does depend on your likes and preferences. Having all of the information at your fingertips about a trip to the Galapagos Islands in August is helpful in making the right choice for you. Here we will consider the wildlife in the Galapagos in August, the weather, the activities and the price and demand during this month to help you make your decision in an informed manner.
The answer: yes, if you book the right vessel and route. No, if you don't.
August is good for divers chasing whale sharks, photographers chasing the densest seabird colony activity of the year, families with school-holiday calendars, and travelers who specifically want cool, dry weather. The water temperature drops to 19–22°C (66–72°F) under the Humboldt Current — bracing for a snorkel without a wetsuit, comfortable with the 3 mm shorty every quality vessel provides.
August is the wrong call if you have a fixed budget below mid-range, if you're motion-sensitive and the only vessel available is a single-hull yacht, or if you wanted the Eastern + Western combined experience and waited until June to start booking. We send roughly half of our August inquiries to the Eastern route on a catamaran, even when the original ask was Western — because Eastern is the calmer route, and the Eastern wildlife (waved albatross still active on Española through November, sea-lion pups starting at Gardner Bay) is genuinely strong in August.
There are many Galapagos Islands wildlife highlights in August. On the land Galapagos fur seals are giving birth. While some lucky visitors may get to experience this, it can be difficult to spot due to fur seals preferring shade and rock, meaning that they are often out of view. Yet California sea lions are also birthing and may be more out in the open. As might be expected, sea lions are very protective of their young, especially while the mothers are nursing their pups. This can lead to more aggressive male behavior in the month of August, so take care!
Galapagos giant tortoises also tend to be plentiful in the Santa Cruz highlands at this time of year – another great highlight of a Galapagos Islands visit.
Among the birdlife, a fabulous highlight is hatching of some waved albatross chicks, as nesting season for this species is well underway in August. If this is a highlight that you hope to see, it is important to make sure that your Galapagos Islands cruise stops at Espanola Island, which is where these massive birds can be found. The young chicks have a darker coloring than the adults with feathers that are blackish brown in color. Another birdlife highlight in August can be the nesting of blue footed boobies too. The good news is that these birds can generally be seen not just on Galapagos Islands cruises but also on Galapagos land-based trips.
In the seas, especially around the western isles of Isabela and Fernandina there is a good chance of spotting humpback whales. These enormous beasts make their way north due to the cooler waters around the Galapagos Islands at this time of year. There is also a decent chance of seeing dolphins in similar western spots in the archipelago. Sea turtles can also be seen swimming around the islands at this time of year.
Whale-shark season at Darwin and Wolf runs roughly June through November, peaking in August and September. This is the SEO and AI-citation overlap that makes August the most-searched Galapagos month — it's the only month where whale-shark search volume meaningfully overlaps with Galapagos-cruise search volume.
Where: Darwin and Wolf islands, in the far north of the archipelago. Female whale sharks aggregate at Darwin's Arch — the natural arch collapsed in 2021, but the dive-site name persists.
Who can go: certified divers only. Most liveaboard operators require Advanced Open Water certification, 50+ logged dives, and Nitrox endorsement. Currents are strong. Surface conditions can be heavy. Non-diver partners are not accepted on these vessels. The islands themselves are closed to non-diver visitors under park permit policy.
How long: 7-night liveaboard minimum. The vessels depart Baltra or San Cristóbal and sail roughly 14 hours northwest to Darwin and Wolf, with 3–4 dives per day at the dive sites and a return transit at the end.
Sighting rates: partner liveaboards we work with report 60–85% trip-success rates across August–September 2024–2025 — well-above the 30% baseline of the shoulder months.
Vessels: dive-yachts only.

The temperature in the Galapagos Islands in August is cool compared to other months of the year. It may be quite overcast some of the time. Do not be fooled – your skin can still burn in this strong equatorial sun, so do pack sunscreen and a hat. There is an average of six hours of sunshine per day in the Galapagos in August. Temperatures are on average 71.5°F (22°C), with the hottest days generally around 77°F (25°C), and the coolest days around 66°F (19°C). It can be windier in the Galapagos Islands in this month so it might feel cool. Bringing some warmer items for travel in these months is recommended.
Rainfall in the Galapagos Islands in August is minimal, and this is one of the driest months of the year. In this month there may be a little bit of rain in the highlands, around 0.2 inches or 0.5 centimeters.
Humidity is lower in the archipelago in August than in other months of the year, but it is likely to feel fairly humid at any time of the year.
Sea temperatures are cool during August, sitting it around 70°F (21°C) on average. The sea can be choppier in August than in earlier months of the year as it can be windy in this months. While winds never reach speeds such as those seen in the Caribbean, the effect of the winds can mean somewhat rougher seas in August. Those that suffer from sea sickness should come prepared with suitable preventative medication, just in case.
As a year-round destination, the Galapagos activities available in August are the same as all the other months of the year. It is worth noting that cooler weather with very little rain makes hiking or walking on the islands a pleasant activity during this month. The weather means that the trails tend to be in good condition too.
An activity that is better in August than in some of the other months of the year is snorkeling. The cooler waters driven by the Humboldt Current means that the food chain is well stocked with nutrients and there is wildlife a-plenty in the waters. This is an excellent time to observe active life in the waters around the islands. The cooler sea temperatures can mean that for some, using a wetsuit may be preferable. Some visitors to the Galapagos Islands enjoy time relaxing through sunbathing. August may not be the best month for that as the skies are often cloudier and the weather not so sunny.
Galapagos prices in August tend to be high due to the exceptionally high demand during the summer months. Holding out for a last-minute bargain cruise is likely to be a mistake. Cruise operators know that with really high demand they can generally fill boats during August so there is no need for special offers to get people on board. Prices of flights, cruises and accommodations all tend to be higher during this popular month for Galapagos Islands visits.
There is no doubt that tourism demand is high in the Galapagos in August. In Europe and in North America, schools are closed for the summer and families take vacations. Galapagos Islands cruises get booked up very far in advance in these months due to the high demand experienced in August. In some cases, Galapagos land-based trips may not be booked up quite so far in advance. This means that if you have left it a bit late to book and all the cruises are full, a land-based trip might be worth a look instead.
While some worry that the high demand might affect their experience in the islands, this is unlikely to be the case. The cruise schedule is structured to ensure that there are never too many tourists on any island at the same time. This is done for the benefit of the wildlife, but it is good for visitors too!
Some of our associated yachts provide rates that are good year-round, including for August departures. Take a look at the Sea Star Galapagos Cruise and the Natural Paradise cruise, among others.
The same cold-water Cromwell Current upwelling that makes the Western route's wildlife so rich also produces the year's heaviest swell on the channel between Isabela and Fernandina. August and September are the peak swell months. The trade winds blow steady from the southeast, the swell wraps around the southern end of Isabela, and on a single-hull motor yacht the Bolívar Channel crossing turns into a hard night and a hard breakfast.
"We always warn our August travelers about the swell on western routes — it's not theoretical, it's real. Around Fernandina Island and the west coast of Isabela Island, we consistently see stronger currents and longer-period waves between July and September. In August 2025, we had a group on the Ocean Spray who were seasoned travelers but still caught off guard — three guests ended up skipping a panga landing at Punta Vicente Roca because of the surge. The wildlife is absolutely worth it, but if someone is prone to motion sickness, we'll suggest they're fully prepared with medication and realistic expectations."
— Marcelo Guerrero, Co-Owner
A few things worth saying out loud about that quote. The Ocean Spray is a luxury catamaran — one of the most stable vessels in the fleet — and the surge at Punta Vicente Roca was strong enough that three seasoned travelers chose to skip the landing anyway. That's the August reality on Western. On a single-hull yacht in the same conditions, the calculus is different again.
No Galapagos vessel has stabilizers that fully eliminate the Bolívar swell. Two practical recommendations we make all August: (a) book a catamaran or trimaran for August Western, or (b) sail Eastern in August and book your Western trip for May or November.
August is the year's roughest month for seasickness on Galapagos cruises, and it lands hardest on the Western route and on single-hull motor yachts. What helps, in order of effect: (1) multi-hull vessel choice — twin or triple hulls cut the roll dramatically; (2) route choice — Eastern's protected lee makes it the August default for motion-sensitive travelers; (3) anti-nausea medication — scopolamine patches or Bonine, started before symptoms; (4) mid-ship cabin location on the lower deck — less pitch, less roll. We cover this in detail in our Galapagos seasickness guide — read it before you book.
The most-asked question we get on August inquiries. Short answer: on-site no, on-board the same as any month, on-booking yes.
We get more "is August right for our family?" inquiries than any other month. This one ran in August 2025.
"We have just returned from the most amazing time in the wonderful country that is Ecuador. Alexandra at Galapagos Insiders handled our booking with the utmost professionalism and responsiveness, answering all our questions and providing updates and information swiftly throughout the booking process. We booked directly with Galapagos Insiders from the UK and were pleased to support a local agency. Alexandra gave us honest advice around security and helped us revise some of our original plans on this basis. We booked an 8-day Galapagos cruise on board Calipso Yacht, a 9-day bespoke guided land tour for our family, and a 4-day Amazon adventure at Sacha Lodge. All were outstanding with excellent accommodation, superb meals, and fantastic, fun guides who spoke fluent English."Kieron (Tripadvisor Review)
The pattern in Kieron's trip is the one we recommend most for August families: 8-day cruise + mainland extension. Quito altitude acclimation, then the Galapagos cruise on a stable vessel, then the Amazon at Sacha Lodge for a contrasting ecosystem. August sea conditions on Eastern routes (Calipso runs Eastern variants) are manageable for kids 8 and up.
While the Galapagos Islands is very busy in August, with lots of visitors, it is still a great time of year for a trip to this unique destination. High demand does mean that for those visiting the Galapagos in August, booking ahead, and especially for cruises, is critical. The weather makes this time of year fabulous for a trip as it is not too hot and there is very little rain. The sea life is particularly special at this time of year with those snorkeling or diving enjoying fantastic underwater entertainment provided by the many species around the islands in August. Whether opting for Galapagos Islands cruises or Galapagos land-based trips, August is unlikely to be a disappointment.
We specialize in Galapagos Islands trips and can help you find the perfect cruise or land-based trip to meet your needs. If you are unsure, get in touch and we can help with any questions or concerns you may have before you make your booking of a lifetime.
Yes for divers chasing whale sharks, photographers chasing peak seabird-colony activity, families on school-holiday calendars, and travelers who specifically want cool, dry weather. Less ideal for budget travelers (10–20% peak-month premium), motion-sensitive travelers on single-hull yachts, and anyone trying to book inside 90 days (best vessels sell out 6–9 months ahead). On a catamaran or trimaran, August is one of the best wildlife months of the year.
The Bolívar Channel between Isabela and Fernandina is at its annual peak swell in August and September — the southeast trade winds are at full strength and the cold-water Cromwell Current upwelling drives 2–3-meter swells. On a single-hull motor yacht, August Western is rough. On a catamaran or trimaran, it's manageable. Eastern routes stay inside the protected lee of the central archipelago and are noticeably calmer. May and November are the Western route's calmest months.
Yes — August and September are the peak window for whale sharks at Darwin and Wolf islands. Sightings on partner liveaboards run 60–85% trip-success rates in those months, against a 30% baseline outside June–November. Whale-shark dives are dive-only: certified divers (Advanced Open Water + 50+ logged dives + Nitrox endorsement) on 7-night liveaboard yachts. Non-divers cannot visit Darwin or Wolf — the islands are closed to non-diver visitors under park policy.
An 8-day August cruise runs from $5,295 on mid-range catamarans (regular 2027 pricing) and from $7,875 on luxury yachts. Shorter 5-day and 6-day departures start from $2,557 (5-day mid-range) and from $3,773 (6-day first-class regular). Add $250–600 for domestic flights (carrier capacity is the year's tightest in August), $200 park entry fee, $20 INGALA card, $200–400 tips. August prices run 10–20% above May. Full breakdown: Galapagos cruise cost 2026.
On-site no — park daily-visitor caps and timed-entry slots regulate every visitor site. Onboard your cruise it's the same 16–100-traveler group all month, identical to any other month. Booking competition is the highest of the year — the best vessels and cabins typically need to be booked 6–9 months ahead. Book early or pivot to shoulder months (May, November).
Layers. Air temperature 18–24°C with persistent garúa drizzle on the highlands — bring a windbreaker (the most-underpacked item), a fleece or light jacket, and quick-dry trousers. For the water, a 3 mm shorty is standard onboard but the cool 19–22°C water rewards bringing your own 3 mm full-suit or rashguard for back-to-back snorkels. Reef-safe sunscreen (Ecuador requires it at protected sites). Closed-toe water shoes for the wet landings. Anti-nausea medication if you're motion-sensitive.
Yes, on the right vessel and route. Eastern routes on a catamaran or stable yacht are the August family default — Kieron's family on Calipso Yacht in August 2025 is a typical pattern. Most vessels accept kids 6 and up; a few require 8 or 12. Avoid single-hull yachts on the Western route in August with kids — the Bolívar swell is a hard introduction to ocean travel. For a family-first land+cruise hybrid (the most-popular August family pattern), see our Galapagos family vacation guide.
Not on a catamaran or trimaran — Western is genuinely worth the August swell on a multi-hull. Penguins, flightless cormorants, marine-iguana mega-colonies on Fernandina, whale sightings in the Bolívar Channel. The route-specific yes. Yes, avoid Western on a single-hull motor yacht in August if you're motion-sensitive. The Bolívar Channel crossings are the year's roughest on a single-hull, and the wildlife is just as accessible from a catamaran. If August Western on a catamaran isn't available, sail Eastern in August and book Western for May or November.
"From start to finish, Galapagos Insiders organized the trip well. Inquiries were answered in a timely manner. The yacht with its crew were excellent. The park interpreter was outstanding, knowledgeable and enthusiastic. I highly recommend this trip."Arabianwings from Canada (Tripadvisor Review) — Grand Majestic, November 2025
