Traveller notes on Puerto Ayora in December

Other months in Puerto Ayora

Regulars are specific this falls within the less-warm half of the year here, June through November, in contrast to the warmer December-through-May stretch, days themselves still genuinely warm even as evenings on a boat turn properly chilly, especially up on the top deck while underway. Our row backs that warm, genuinely dry read, 27.9C over 22.8C nights feeling 25C, with rain minimal at 9.8mm across 4 days and humidity at 77 percent. Regulars are consistent conditions stay genuinely variable day to day, some trips reporting mostly cloudy skies, others a good mix of sun, a light jacket for evenings the standard advice throughout this half of the year. The sea sits at a warm, swimmable 27.9C. The record: 10.9 hours of sun, a 20.5 kph wind and AQI 34.

July opens the garua season here, when the colder Humboldt current pushes up from the south and brings mistier mornings and evenings, though someone who lived here four years describes the pattern precisely: the mist gathers near the islands and dissipates by mid-morning before reforming later, leaving genuine sunshine in between - our column's 10.6 hours a day fits that pattern of clearing rather than an overcast month. Reports vary from almost no mist at all to two mornings out of eight, so neither extreme is the rule. Our row backs the season's coolness at 27.1C over 22C, with the sea at 26.7C - regulars still recommend a wetsuit for snorkelling even though the water rarely feels cold in the tropics sense. Evenings on a boat want a sweater. Rain is negligible, 5.5mm across 2.2 days. The record: humidity 76 percent, a 21 kph wind and AQI 33.

November is the last of the garua months and the beginning of the turn. Regulars describe the same pattern as October - misty early and late with fine drizzle, good sun between about eight and four - but add that the sea is starting to settle, though not yet as calm as it gets from January to May. They put the water at 20 to 23C and say wetsuits are still wanted for snorkelling; our row reads 24.6C, so treat theirs as the figure to pack for. It is also the last reliable month for the waved albatross on Espanola, which leaves around now. Our row gives 27.1C over 21.4C with 2.5mm across a single precipitation day. The record: humidity 73 percent, 11 hours of sun, a 20.3 kph wind and AQI 32.

October sits in the garua season, roughly June to November, and the reputation is worse than the experience. Regulars describe low cloud dropping a fine mist that forms near the islands and lifts mid-morning, so the sky is usually clear from about nine until three or four and you still get six to ten hours of sun - our row says 10.8. What our figures cannot show is the mist itself: 2.2mm across 0.9 precipitation days is a month our gauge calls dry. The season's real costs are choppier seas and cooler water, 24.9C here, cold enough that snorkellers want a wetsuit, with fresh early mornings and evenings under a 26.7C day. Wildlife is good all year; the one deadline is the waved albatross on Espanola, gone by about November. The record: humidity 74 percent, a 20.7 kph wind and AQI 28.

Recurring seasonal events, natural spectacles, closures and holidays — curated and sourced.

  • Rule

    Galapagos park entry fee

    1 Jan – 31 Dec

    The national park fee doubled in August 2024, the first rise since 1998, and it is paid in cash US dollars on arrival at Baltra or San Cristobal. There is a separate transit card before you fly, and no cards are accepted at the desk. Source ↗

  • Nature

    Waved albatross on Espanola

    1 Apr – 20 Dec · usuallyBirdlife season

    The entire world population nests on one island, arriving at Punta Suarez in April and gone again by the end of December. Espanola is a full day out by boat, so it is a cruise itinerary rather than a taxi ride.

  • Nature

    Tortoises in the highlands

    1 Jun – 15 Dec · usuallyWildlife season

    Santa Cruz's wild tortoises spend the cool grey months up in the wet pastures, which is when the ranches on the road to Santa Rosa are thick with them. They walk back down to nest in the warm season.

  • Nature

    Green turtle nesting

    1 Dec – 30 Jun · usually

    Green turtles haul out on Tortuga Bay and the quieter beaches from December, and the park ropes off the nesting end until the last hatchlings are away around June. Night walking there is out.

  • Season

    Warm season and calm crossings

    15 Dec – 31 MaySea warm enough

    Warmer water, flatter seas and short heavy showers that green the islands. This is the half of the year for snorkelling without a wetsuit and for anyone who does not want the inter-island ferry to be an ordeal.

  • Holiday

    Christmas and New Year peak

    15 Dec – 10 JanChristmas & New YearCrowdedBook early

    The second peak of the year, and the shorter one: mainland Ecuadorians and long-haul visitors arrive together and the cruise boats charge their highest rates of the calendar for the fortnight. Source ↗
