Best times to visit Galapagos

There is never a bad time to visit the Galapagos. There is always something different happening.

Weather-wise, no time of year on the Galapagos has perfect weather, so deciding when to visit the islands based on weather is very much a personal decision.

December to May is the warmer, wetter season. The warm Panama currenty usually dominates over this time bringing sunny weather with occasional tropical showers that turn the islands green. Seas are generally calm, the average temperature is 26C and underwater visibility is good, all ideal conditions for snorkelling and swimming. The daytime air temperature is generally 26-30C, but rather humid.

Between June and November the weather is cooler and drier under the influence of the Humboldt current. Temeratures are typically 23-26C, reduced by wind-chill that can make it a bit nippy to be on deck without the fleece. Skies are often cloudless and rain is scarse, but a fine mist called garua can cloak the highlands.

For wildlife, the natural year on the Galapgos is always changing and there is plenty to see at any time, so there is never a 'wrong' time to visit. Here is a summary of what you can expect to find month-by-month.

December The islands green over as the rainier season starts. Still great weather: mostly sunny days, hardly any wind, waters warmer. Giant tortoise eggs hatch from now until April. Pacific green turtles breed on Santa Cruz. Waved albatrosses fledge. First red pouches of great frigatebirds at Genovesa. Northern migrant birds and somewhales and dolphins rest and feed on their journey south.

January Land birds nest. Marine iguanas turn green, red and black on Espanola. Green sea turtles arrive to lay eggs until March. Land iguanas breed on Isabela. Nazca boobies nest on Espanola. Air and seas are warm until June. Ideal for snorkelling.

April Rains end, yet islands remain green. Waved albatross mass arrival and courtship, Espanola. Green sea turtle eggs begin to hatch. Land iguana eggs hatch on Isabela. Giant tortoise hatching season ends. Good visibility for snorkellers. Together with May one of the best months to visit.

Waved albatross start to lay eggs on Espanola. Band-rumped storm petrels start nesting. Sea temperature starts to drop towards the end of the month.

June Start of the drier season. Southeast trade winds return, currents become stronger, seas pick up. Giant tortoises on Santa Cruz migrate from highlands to lowlands in search of nesting places.
