Diving in the Galápagos in June

Conditions in June

Diving the Galápagos in June plunges you into the cooler, dryer season, which, counterintuitively, often means more prolific marine life. This is when the Humboldt Current begins to assert its full influence, bringing nutrient-rich waters from the south. You can expect air temperatures to average around 20-25°C (68-77°F), making surface intervals quite comfortable, though a light jacket is always a good idea for evenings. The sea state during June can be a bit choppier than in the warmer months, especially around the exposed northern islands like Darwin and Wolf. This is part of the experience, as these slightly rougher conditions are what churn up the nutrients.

Water temperatures in June are firmly in the cooler range, typically hovering between 20-24°C (68-75°F) for most dive sites, though thermoclines can bring localized drops down to 18°C (64°F) or even lower in some areas. Visibility, while generally good, can vary. Around the more plankton-rich sites, especially where you find large aggregations of filter feeders, it might range from 10-20 meters. At other times and locations, particularly where currents are sweeping clean water through, you could easily enjoy 20-30+ meters of clarity. Currents are a defining feature of Galápagos diving, and in June, they are typically present and often strong. Prepare for exhilarating drift dives and negative entries – this is not a destination for the faint of heart when it comes to current.

What you will see

June is, for many, the sweet spot for Galápagos diving due to the abundance of pelagic life. The cooler, nutrient-rich waters brought by the Humboldt Current act like a siren call to large marine animals. This is peak season for hammerhead sharks, and you can expect to encounter massive schools of scalloped hammerheads off Darwin and Wolf Islands. Whale sharks also begin to make their appearance in significant numbers during June, attracted by the increased plankton. Spotting these gentle giants is a highlight for many divers, and June offers some of the best chances throughout the year.

Beyond the headline acts, you'll witness an incredible diversity of marine life. Galápagos sea lions are always playful companions, and in June, they are particularly active. You’ll see them zipping past you, playing with your fins, and showcasing their incredible agility. Galápagos penguins are more frequently sighted and active during these cooler months, especially around Isabela and Fernandina, as the upwelling provides rich feeding grounds for them. Manta rays, eagle rays, and marble rays are common sights, gracefully gliding through the water. Moray eels, including the endemic Galápagos moray, hide in crags, while various species of reef fish, including parrotfish, angelfish, and snappers, populate the reefs. Keep an eye out for the unique marine iguanas, a true Galápagos icon, foraging on algae along the coastlines.

While macro photography isn't the primary draw of Galápagos, you'll still find interesting invertebrates if you look closely. Octopus, nudibranchs, and various crabs and shrimps can be spotted by the keen-eyed diver. However, the true spectacle in June lies in the sheer volume and diversity of large marine species drawn to the productive waters. Prepare for an epic encounter with some of the ocean's most charismatic megafauna.

Top dive sites this month

For sheer pelagic action in June, Darwin's Arch (and its surrounding sites) and Wolf Island are undeniably the kings. These northernmost islands are where the magic truly happens. At Darwin's Arch – even though the arch itself is now gone, the dive sites around it remain phenomenal – you’ll drop into a hammerhead shark sanctuary. Schools of hundreds are not uncommon, often joined by Galápagos sharks, silky sharks, and whale sharks. The famous ‘The Arch’ dive site offers a spectacular experience as you gaze out into the blue. Wolf Island, slightly south of Darwin, offers equally thrilling encounters at sites like ‘Shark Bay’ and ‘The Caves’, where strong currents sweep plankton-rich water past volcanic walls, attracting more schooling hammerheads, large groups of Galápagos sharks, and occasionally whale sharks.

While Darwin and Wolf are the main draw for June, other sites offer complementary experiences. Vicente Roca Point on Isabela Island is excellent for finding mola mola (ocean sunfish), especially in the cooler water, and potentially penguins and more endemic marine life. Cousin's Rock, near Santiago Island, is a fantastic seamount teeming with barracuda, white-tip reef sharks, eagle rays, and a vibrant reef system. Lastly, Punta Carrion, near Santa Cruz, while often a check-out dive, can surprisingly offer good encounters with white-tip reef sharks, eagle rays, and playful sea lions, particularly when the currents are favorable. These sites offer a superb mix of pelagic action and unique Galápagos encounters to round out your itinerary.

Practical tips for your trip

Given the cooler water temperatures in June, a robust wetsuit is essential. We strongly recommend a 7mm full wetsuit, and many divers will also want to add a hooded vest or hooded full suit for extra warmth, especially if you get cold easily or are planning multiple dives a day. Think about your personal tolerance for cold – it's always better to be too warm than too cold underwater in the Galápagos! This month is generally best suited for experienced, confident divers. The currents can be strong, and the dives often involve negative entries and drift diving. While an Open Water certification is typically the minimum requirement, advanced certifications and experience with strong currents will enhance your enjoyment and safety.

Liveaboard availability for June, particularly on the higher-end vessels that visit Darwin and Wolf, books up far in advance due to the popularity of this season. We advise booking at least 12-18 months ahead to secure your preferred boat. What to pack? Besides your heavy wetsuit, bring reef-safe sunscreen, a wide-brimmed hat, sunglasses, and a windbreaker or light waterproof jacket for those surface intervals and zodiac rides. Definitely pack some seasickness medication, even if you rarely get seasick; the journey to Darwin and Wolf can be rocky. Finally, be aware that Galápagos is a highly protected national park. Follow all park rules diligently, including refraining from touching marine life and adhering to your dive guide's instructions. Enjoy one of the world's most incredible diving destinations!
