When to visit Galapagos Islands
There is no real ‘best’ time as something is always happening and Galapagos are a great year-round destination for a holiday.
As the Galapagos Islands are located right on the equator, air and water temperatures do not vary by much, and most species are here year-round.
There are two recognised seasons, and each months brings natural marvels to the fore, listed here in in our month-by-month guide to the highlights of Galapagos.
Don’t forget to check our Galapagos photos on Facebook, Pinterest and Youtube videos.
The warm season (Jan-Jun)
The warmer months bring calm, warm waters (around 70°F range) and sunny days (72-9°F or 22-32°C), February and March being the hottest and sunniest months with blue skies and sunshine.
The islands receive slightly more rainfall during these months, occasional heavy bursts in the afternoon. Great for snorkelling and you can spend a lot of time in the water without wetsuits, with great, clear waters.
The dry ‘garua’ season (Jun-Dec)
It’s a great time for marine life. August and September the coolest when you may need a jacket in the evenings and the sea can be choppy and temperature drops around 15-24ºC on average.
There can be mist on the islands in the mornings (garua) which usually burns off by midday leaving overcast skies or a sunny afternoon.
Sea temperatures may drop to 60°F- 72°F (15-22°C) during this time and snorkellers will want a wet suit for prolonged periods in the sea.
