Unlike most destinations, the Galapagos Islands don’t really have a single “best” month so much as two very different seasons, each with its own wildlife highlights, weather and diving conditions. Straddling the equator, the archipelago stays warm year-round, but ocean currents change dramatically between December and November, and that shift affects everything from snorkeling visibility to the animals you’ll see. Here’s how to choose the right time for your trip in 2026.
Galapagos Has Two Seasons, Not Four
The islands experience a warm, wetter season from December to May, and a cooler, drier season from June to November. Both are good times to visit – the “best” one really depends on what you want to see and do.
Warm Season (December-May): What to Expect
Warmed by the Panama Current, sea temperatures climb into the mid-to-upper 70s F (24-27C), skies are sunnier, and short tropical showers are common in the afternoons. Calmer seas make this the most comfortable period for snorkeling and swimming, and it’s also when giant tortoises nest and marine iguanas display their breeding colors. January and February bring particularly warm water and lush, green landscapes.
Cool/Dry Season (June-November): What to Expect
The Humboldt Current brings cooler, nutrient-rich water that draws in larger marine life – think whale sharks, hammerhead sharks and huge schools of fish, making this the season serious divers wait for. Days are drier with more overcast skies and cooler air temperatures, and choppier seas can make some crossings bumpier. September is considered prime time for experienced divers, while October offers calmer water and excellent visibility.
Best Month by Interest
- Best for snorkeling: January-May, when the water is warmest and calmest.
- Best for diving with big marine life: June-September.
- Best for families: December-April, thanks to warm water and gentler seas.
- Best to avoid crowds: Early December, early January, or September, just outside the peak holiday windows.
Which Season Is Better for Island Hopping on a Budget?
Shoulder-season months – May, June, September and early December – tend to offer the best balance of good weather, fewer crowds and more availability on budget-friendly island-hopping itineraries, since demand dips right between the two peak periods (the December-January holidays and the June-August travel season).
Frequently Asked Questions
Is there a rainy season in the Galapagos?
Yes, loosely from December to May, though showers are typically short and don’t usually disrupt a day of touring.
What’s the water temperature like for snorkeling?
It ranges from around 68F (20C) in the cool season to the mid-70s F (24C+) in the warm season, so a wetsuit is worth considering outside of the warmest months.
Do I need to book my Galapagos trip far in advance?
Yes, especially for July-August and the December holidays, when permits and boat space fill up months ahead.
