Water temperature: 25°C (77°F)
During the Wet Season, spanning from January to March, travelers can expect average air temperatures ranging from a comfortable 22°C to a warm 31°C (72°F to 88°F), while the water temperature typically hovers around a pleasant 25°C (77°F). Although this season lasts only four months, it brings the highest levels of precipitation, often manifesting in afternoon or evening rain showers. Fortunately, these intermittent showers rarely disrupt planned activities, allowing you to still enjoy your excursions without much interruption. However, if you choose to travel during this period, it’s wise to pack some rain gear to stay dry and prepared. One notable benefit of visiting during the Wet Season is the inviting warmth of both the air and water, which enhances your snorkeling experience, making it not only enjoyable but also more comfortable. The lush, vibrant landscapes that thrive during this time of year add another layer of beauty to your travels, enriching your overall experience.

Water temperatures: 22°C (72°F)
Also known as the 'Garua' season, this season is a distinctive period in the Galapagos Islands, characterized by the presence of morning mists and drizzles that create a serene and mystical atmosphere. These ephemeral conditions, brought about by the convergence of cold-water currents and cooler air temperatures, are a result of the unique geography and oceanic dynamics that surround the archipelago. While the sun rises and casts its warm rays, the mist is quickly dispelled, giving way to bright and sunny days with clear blue skies. However, this tranquility is not without its challenges, as snorkelers and divers often require a wetsuit to protect themselves from the chilly waters, especially during lengthy underwater excursions.
As the 'Garua' season progresses, visitors may need to pack accordingly, with a wetsuit being a must-have for those who wish to explore the Galapagos' incredible marine life. In the evenings, a light jacket or fleece is highly recommended to ward off the cool temperatures that prevail during this time. It's not uncommon for the temperature to drop significantly, especially in the northern regions of the islands. As the final days of the 'Garua' season approach, the skies begin to darken, and the air is charged with anticipation. It's not long before the first rains of the new season make their appearance, typically arriving in late December and signaling the end of the misty, magical 'Garua' period. As the rain falls, the islands undergo a transformation, and the landscape is reborn, setting the stage for the next cycle of growth and renewal.
To put this climate information into practice, many visitors plan their Galapagos experience around the weather and sea conditions that best match their interests, whether that’s warm water for snorkeling or calmer seas for wildlife watching. One excellent way to do this is aboard a thoughtfully designed small yacht, where expert guides can match your itinerary to daily conditions and seasonal highlights. The Natural Paradise Galapagos Cruise is a luxury option that strikes a great balance between comfort and exploration, with flexible itineraries that take advantage of the best weather windows throughout the year. Sailing with the Natural Paradise Cruise can help you make the most of the air and water temperatures outlined above, especially if you are timing your trip around the warmest snorkeling conditions or cooler dry season excursions.

The Galapagos Islands are known for their unique and predictable climate, but there's one phenomenon that can disrupt this balance: El Niño years. These events occur every 2-7 years, with varying intensity, and have a profound impact on the islands' ecosystem. During an El Niño year, the trade winds and ocean currents that normally bring nutrient-rich water from the Antarctic Humboldt Current to the Galapagos shift away, reducing the upwelling of these essential nutrients. As a result, the ocean temperatures rise above normal, leading to an increase in rainfall and a transformation of the highland foliage into a vibrant tapestry of green.
While El Niño years may seem like an ideal time to visit the Galapagos, with lush vegetation and an explosion of greenery, it's essential to consider the potential consequences for the island's fragile marine ecosystem. Stronger El Niño events can be detrimental to species like marine iguanas and tropical fish, which rely on the growth of algae and phytoplankton for survival. These species are crucial to the Galapagos' biodiversity, and their decline can have far-reaching consequences for the entire ecosystem.
However, it's not all doom and gloom. Mild to moderate El Niño events can still make for a great Galapagos vacation. The increased rainfall can create opportunities for snorkeling and diving in areas that are normally too dry, and the warmer waters can make for more comfortable swimming conditions. Additionally, the lush vegetation can provide a unique perspective on the islands' natural beauty. With careful planning and consideration, it's possible to have a fantastic Galapagos experience during an El Niño year, while also being mindful of the potential impact on the environment.
