The weather in the Galapagos varies between two seasons.
The “dry season” (from June to December) is when the air is cooler, with cloudy days and a light rain called garua. This is the perfect time to observe the sea birds with their courtship displays and is the time when sea mammals and land birds are most active.
The “warm and wet season” (from January to June) is when the weather becomes more tropical, with skies that are usually clear but with occasional heavy showers. The ocean temperature gets warmer too, which is great for snorkeling.
