Galápagos in July
July is the month the dry season stops being a technicality. Air temperatures drop, the garúa mist parks itself over the highlands, and the first choppy seas of the year start to build. It is also one of the busier months in the islands. The wildlife calendar doesn’t care about crowds: this is when some of the most specialized animals in Galápagos get down to breeding.
Weather in July
Days average around 24 °C and nights fall to about 20 °C. After the wet season’s heat the change is real: you will want a light layer for mornings on the water, and the highlands of Santa Cruz stay wrapped in mist for much of the day. This is the Humboldt current at work. It drags cold water up the coast, the air cools with it, and the fine drizzle locals call garúa keeps the upper slopes green through the dry months. On the coast, gray mornings often give way to bright afternoons.
Rain is minimal. The arid lowlands stay exactly that: arid.
The sea in July
July is when the sea starts to pick up. It is nowhere near the roughest stretch, which runs August through October, but longer crossings begin to feel it. Water temperature drops to around 22 °C by operator averages; satellite readings of the sea surface at Puerto Ayora run a bit warmer, near 23.5 °C. Either way, the difference from February is something you feel within minutes of jumping in.
We tell guests to rent a wetsuit for snorkeling from June through November. A shorty is usually enough in July. You will still swim comfortably, just not indefinitely.
Wildlife in July
July’s headline act is the flightless cormorant. On Fernandina and the west coast of Isabela they court and nest now, and with roughly a thousand breeding pairs in existence, catching them in courtship is a genuine privilege rather than a given.
Worth planning around as well:
- Blue-footed boobies on Española are nesting in four different stages at once, so courtship displays, eggs, small chicks and near-fledged young can all appear on a single walk.
- Humpback whales are still in the Bolívar Channel between Isabela and Fernandina; their season runs June through September.
- Oystercatchers nest on Santiago, loudly.
- Lava lizards are in courtship display and will stay at it until November.
- Giant tortoises are down in the lowlands laying eggs, a pattern that runs June to November.
Marine iguanas, sea lions and the year-round residents take no season off, so no monthly list is ever complete. It rarely needs to be.
Who July suits (and who it doesn’t)
July works well if you want active breeding behavior and don’t mind cool water and brisker seas. It is a strong month for divers and for snorkelers who accept a wetsuit, because the cold, nutrient-rich water that makes it chilly is the same water that feeds the marine life.
It is a poor fit if your priority is warm, glassy snorkeling; wait for November or the wet season. And if crowds bother you, know that school-holiday demand makes July one of the fuller, pricier months in the islands.
Booking advice for July
Book early. Good boats fill first for July, often months out, and the yachts left in the last-minute market tend to be the ones nobody wanted. Budget for the fixed costs too: the park entrance fee is $200 for foreign adults (it doubled in August 2024) and the transit card costs $20 before you fly. Our guide to entry fees breaks it all down.
If you are weighing July against its neighbors, Galápagos in August goes colder and rougher still, and Galápagos in September covers the roughest sea of the year. Coming from the warm side? Galápagos in June explains how the switch begins.
