Is December a good time to visit the Galapagos Islands?

In short, December is a great time to visit the Galapagos Islands. First up, the Galapagos weather in December is starting to warm up.  Indeed, December marks the start of the warm season. 

This period offers clear, blue skies and warmer sea temperatures that are ideal for diving, snorkelling and swimming. 

Back on land, December also kicks off the breeding season for many of the islands' unique species, including magnificent frigate birds and sea lions.

Being holiday season, December is high season around these parts, which means you might not consider it the best month to visit if you’re not keen on bigger crowds, or higher costs — more on those subjects later.

What about crowds and costs?

There’s no getting away from the fact that the Galapagos Islands are busy in December. In fact, this is peak season at its peak.

Given its popularity, it's essential to plan your trip well in advance. Booking tours, accommodation, and flights early will help you make the most of your trip.
