Galápagos Islands · Month comparison

August vs May

May ranks #1 overall vs August at #12. Shoulder season at its best: low prices, few visitors, and the last warmth before the Humboldt Current brings the cool season.

Galápagos August — wildlife on the volcanic shore in cool season

August

#12 of 12 months

Strong option

Whale sharks return to Darwin and Wolf Islands while blue-footed boobies raise chicks — peak season prices for peak season wildlife.

  • Darwin and Wolf Islands whale shark season resumes (August–October): pregnant females aggregating at the same sites as February but with warmer air temperatures making surface intervals more comfortable
  • Blue-footed booby chicks visible across Española and North Seymour alongside adults in active parenting: a different and in some ways more intimate experience than the pure courtship displays of July

May

#1 of 12 months

Best match

Shoulder season at its best: low prices, few visitors, and the last warmth before the Humboldt Current brings the cool season.

  • The lowest visitor numbers of the year (outside June–July which ironically sees more): last-minute liveaboard availability and day-cruise prices at their annual minimum
  • Rain essentially over (30mm — lightest of any month) with increasingly clear skies as the Humboldt Current begins its approach: good conditions for both snorkelling and island hikes

August trade-offs

  • Same peak pricing as July with no relief: the busiest two-month window of the cool season coincides with northern hemisphere school holidays and maximum liveaboard capacity
  • Coolest water of the year (15–18°C): comfortable in a 3mm wetsuit but cold for extended snorkelling sessions without proper thermal protection

May trade-offs

  • Not peak season for any single dramatic wildlife spectacle: a transitional month where warm-season highlights are fading and cool-season highlights haven't peaked yet
  • Cool-season winds beginning to build: inter-island crossings in the open ocean between the main island groups becoming choppier than during January–March
