There are two seasons. The "rainy" season is January through June and the "dry" season is July through December. We are going in May, but don’t fret about the weather. The seasons are misleading. The "rainy" season has many warm, sunny periods interspersed with rain showers – it is generally pleasant. The "dry" season is cooler and the often misty enveloped with fog. Water temperatures are a balmy 70F and are great for snorkeling. Air temperature is in the mid to high 80’s. Whet your appetite and see what the weather is like in the Galapagos Islands right now.
