The Galapagos are a year-round destination offering plenty to see and do at anytime during the year. Typically the year is divided into two seasons: cool and dry (June to November) and warm and wet (December to June).
From December to June, humidity is high and average temperatures are in the 80s F (26-30C). There may be occasional showers, but days are generally warm and sunny with calm seas. The start of the new year is when green turtles lay their eggs and considered one of the best times to visit. From February, March, and April are typically warmer weather and breeding or nesting season as well as blossoming flowers.
From June to November, you can expect cool winds, occasionally bringing with them a light misty-type drizzle called “garúa.” Temperatures average in the 70s F (20°-24° C) during the day and lower at night. Winds can cause choppy seas, especially in open water between the islands. The colder climes of June through to November send an abundance of plankton and nutrients to the rougher seas off the coast of the Galápagos via the Humboldt Current. This provides sea birds, such as albatross and penguins, with food and typically brings larger fish to feed on this abundance of food.
Each month brings unique climate variations and wildlife viewing opportunities. Peak season for naturalist tours is typically December through May when the seas are the calmest and the weather the warmest. However summer months June, July and August are also very popular as the animals are more active. September through November is typically low season when most boats will leave the islands for dry dock. For divers peak season is from July – November when whale sharks can be found at Wolf & Darwin.
