The best time to visit the Galápagos
Short answer
There is no bad month in the Galápagos — the two seasons are good at different things. December to May is warm, the sea sits around 24–26 °C, crossings are calm and underwater visibility is at its best: the easier trip, and the right one for families and anyone unsure about boats. June to November is cool and choppy — sea around 20–22 °C, wetsuit weather — but the Humboldt current brings the richest marine life of the year. If you want one answer: March–April for the water, September for the wildlife and the price.

Already decided when? The other half of the planning is how you actually get there — the flight only goes from mainland Ecuador, and only in the morning.
The short answer, before the detail
| If you want… | Go | What you are trading |
|---|---|---|
| Warm, calm, clear water | Dec – May | Slightly less marine action; short heavy showers |
| Maximum wildlife | Jun – Nov | Cool water, choppier crossings, a wetsuit |
| Fewest people | September | Nothing much — it is the quiet secret of the calendar |
| Best value | Sep, and late Apr – early Jun | Nothing. This is simply when to book. |
| No seasickness | Dec – May, land-based | See cruise vs island hopping |
Two seasons, and neither is “low”
Most destinations have a high season and a low one. The Galápagos does not. It has a warm season and a cool season, set by ocean currents rather than by rain, and the wildlife calendar is different in each. Calling one of them “low season” is a marketing habit, not a description.
December to May — the warm season. Air around 28–30 °C, sea 24–26 °C. Brief, heavy afternoon showers that clear. The sea is calm, crossings between islands are gentle, and underwater visibility is at its annual best. Land birds breed, marine iguanas turn red and green on Española, and green turtles nest.
June to November — the cool season. The Humboldt current arrives. Air drops to 22–25 °C, sea to 20–22 °C, and the water turns nutrient-rich. Everything that eats follows it: seabird colonies at their busiest, sea lions pupping, hammerhead numbers peaking. It is choppier, you will want a wetsuit, and the highlands sit under a fine mist called garúa.
Nobody misses the Galápagos by coming in the wrong month. They get a different one.
Diving splits harder on season than anything else: the hammerhead schools form in the cool season, the visibility peaks in the warm one. Diving season by season →

Temperatures are typical ranges for the inhabited islands. The western coasts of Isabela and Fernandina run several degrees colder all year because of the Cromwell current — which is why the penguins live there.
If you are coming for one particular animal

Crowds and price are not the same thing
People assume high season means expensive. In the Galápagos it mostly means full.
Land arrangements move very little between seasons — across our own programmes the cost sits in a narrow band of US$245–262 per day in the standard category all year. What moves is the flight from the mainland, which swings from around US$400 to US$600, and availability: the good hotels on Isabela and the boat spaces sell out well before they get expensive. We costed the whole thing out in the Galápagos price index.
The two peaks are mid-December to mid-January and July to August. The quietest month of the year is September, and it is also when the wildlife is at its best — which is the closest thing to a free lunch the calendar offers.
If you are worried about seasickness
This decides more trips than the wildlife calendar does, and almost nobody writes about it honestly. Two things reduce it, and they compound:
- Travel December to May. The warm season is measurably calmer. August is the roughest month of the year.
- Sleep on land, not on a boat. A land-based itinerary means two or three inter-island crossings of about two hours each, rather than a vessel that moves every night while you are trying to sleep.
If both matter to you, the answer is a warm-season, land-based trip — and we will say so even though a cruise is the larger sale. The full comparison is here.
The worst time to go, and it is not about weather
Mid-December to mid-January. Not because of rain — the wildlife and the water are good. Because flights peak, hotels fill, Ecuadorian domestic travel lands on top of international, and the visitor sites are at their most crowded. If you can move a week either side, do.
The only genuine weather caution is August, and only if you are prone to seasickness. And the only real wildlife caution is a strong El Niño year, when the warm water starves out the algae and the fish — marine iguanas shrink, sea lion pups die and penguins stop breeding. That is not predictable a year ahead.
Which of our trips suits which season
| Programme | Days | When it is at its best |
|---|---|---|
| 5-Day Galápagos: Santa Cruz & Isabela | 5 | Year-round. December–May is warmer with calmer seas and the best visibility; June–November is cooler and rougher with the richest marine life. |
| 8-Day Galápagos: San Cristóbal, Santa Cruz & Isabela | 8 | Year-round. Kicker Rock visibility is best December–May; hammerhead numbers peak June–November. |
| 6-Day Luxury Galápagos | 6 | December–May for calm water and visibility; June–November for marine life. |
| 6-Day Galápagos Multisport | 6 | Year-round; June–November is cooler and easier for the Sierra Negra hike. |

Questions people also ask
What is the best time to visit the Galápagos?
There is no bad month. If you want warm, calm, clear water — the easier trip, and the better one for families and nervous swimmers — go December to May, with March and April the pick. If you want the richest wildlife and do not mind cool, choppy seas, go June to November, with September the quietest and best value.
What is the worst time to visit the Galápagos?
Nothing is bad for wildlife. The window we actively steer people away from is mid-December to mid-January, and it is not about weather: flights peak, hotels fill and the sites are at their busiest. August is the roughest sea if you are prone to seasickness.
When is the water warmest in the Galápagos?
February and March, at around 26 °C. By August it has dropped to about 20 °C, which is a wetsuit rather than a swimsuit. That 6 °C swing is the single biggest practical difference between the seasons.
What is the cheapest month to visit the Galápagos?
September, followed by late April to early June. The land arrangements barely move between seasons — what moves is the flight from the mainland, which can swing from around US$400 to US$600, and hotel availability.
When is the best time to avoid seasickness in the Galápagos?
December to May. The warm season brings calmer seas and gentler inter-island crossings. If you are genuinely prone to it, that window plus a land-based itinerary — hotels rather than a moving boat — removes almost all of the problem.
Do the Galápagos have a rainy season?
The warm season, December to May, brings short heavy showers that clear quickly, usually in the afternoon. It is not a washout, and the islands are at their greenest. The cool season is drier but comes with a persistent highland mist called garúa.
When can you see whale sharks in the Galápagos?
June to November, at Darwin and Wolf in the far north — which are liveaboard dive sites only. No land-based itinerary and no standard cruise reaches them, and any operator suggesting otherwise is selling you something else.
How far ahead should I book?
For June to August or the Christmas window, three to six months. That is when the island flights, the good hotels and the boat spaces run out — not when they get expensive.
