A question we often hear is, “what is the best time to visit the Galápagos?” That sounds like an easy question, but the answer depends on what you’d like to do and see. The islands have a subtropical climate with two main seasons. The land and sea temperatures are affected by currents such as the cold Humboldt and the warmer El Niño. Each season provides an array of activities from snorkeling to watching mating rituals.
The Warm Season (December–May)
This is the warmest time of year and receives slightly more rainfall. The sea is at its warmest and is usually calmer. Although the islands receive more rain, the lower elevations of the islands—where you will spend most of your trip—offer blue skies and sunshine with occasional haze.
The Cool Season (June–November)
The drier garua season offers plenty of sunshine during the day, but it is less intense, with cloudier skies. Air temperature is lower, with highs in the upper 70s or mid-80s. The water temperature is at its coolest. During some years, the El Niño current may cause a much greater flow of warm waters, making the surface warmer and rainfall increase.
