The seasonal pattern for Galápagos — what each stretch of the year tends to bring, and what to plan around. Guidance, not a forecast.
Seasonal pattern, not a forecast — conditions vary; verify tides, weather and visibility locally before you go.
The archipelago sits on the equator, so its seasons are about water and current rather than air temperature. The warmer, calmer window is broadly December to May, which is what most snorkelers aim for; the cooler, drier season, broadly June to November, is driven by the Humboldt current and brings noticeably colder water with richer upwelling, so a wetsuit becomes the difference between a comfortable hour in the water and a short one. Visibility varies with the plankton that same current brings, which means the clearest days and the most life are not always the same days. And because almost everything here happens by boat and under park rules, weather and permits shape the itinerary more than a snorkeler's preference does — verify current conditions and site access locally rather than planning a fixed list far ahead.

Live conditions decide the day, not this page — check the local marine forecast and tide or water-level information for your dates before you go.

The Galápagos is not a carefree beach trip and this catalog will not describe it as one: it is a tightly regulated national park, where a park entry fee is collected on arrival, many sites can only be visited with a licensed naturalist guide, and you reach the islands by flying from mainland Ecuador to one of the archipelago's two airports. It is also one of the few places on earth where you can snorkel beside sea lions and Galápagos penguins. The water runs cool on the Humboldt current, so exposure protection is normal rather than optional.
