The Galápagos Islands, located on the equator, do not experience the traditional four seasons found in temperate zones. Instead, the archipelago has two distinct seasons driven by shifting ocean currents: the Warm Season (December through May) and the Cool Season (June through November).
Because wildlife activity is constant, there is no “bad” time to visit. However, your decision should be based on your preference for air temperature, water warmth, and specific wildlife patterns.
Quick Reference Guide:
| Feature | Warm Season (Dec–May) | Cool Season (Jun–Nov) |
|---|---|---|
| Air Temperature | Warm & Humid (75°F–85°F) | Cool & Breezy (65°F–75°F) |
| Water Temperature | Warm (70°F–76°F) | Cool (60°F–70°F) |
| Ocean Conditions | Generally calm | Choppier (due to currents) |
| Vegetation | Lush and green | Dry lands, misty highlands |
| Best For | Snorkeling, swimming, calm sailing | Marine life viewing, hiking |
The Warm Season: December to May
The Galapagos’ warm season is characterized by the arrival of the warm Panama Current. While it is technically the “rainy” season, precipitation usually comes in the form of short, heavy daily showers that quickly give way to bright sunshine.
Weather & Ocean Conditions
- Climate: This is the hottest time of year with daily highs typically between 82-88°F. Humidity is higher, and the sun is intense.
- Water: The ocean is calm and warm, offering excellent visibility. This is the ideal time for travelers who want to snorkel without thick wetsuits.
- Landscape: The rain transforms the arid islands into lush, green landscapes, providing a beautiful contrast against the volcanic rock and blue ocean.
Wildlife Highlights
- Land Birds & Reptiles: The abundance of vegetation makes this the prime mating and nesting season for land birds, marine iguanas, and sea turtles.
- Green Sea Turtles: Nesting is at its peak; you may see tracks on the beaches.
- Waved Albatross: In late March or April, these massive birds return to Española Island to begin their courtship rituals.
| Month | Air Temp. (Avg High) | Water Temp. | Key Wildlife & Activities |
|---|---|---|---|
| December | 82°F | Warm | Giant tortoises start hatching. Green sea turtles begin mating. |
| January | 84°F | Warmer | Marine iguanas start nesting on Española. Land birds begin nesting. |
| February | 86°F | Warmer | Marine iguana nesting on Fernandina. Galapagos doves are nesting. |
| March | 88°F | Warmest | Peak sun and heat. Marine iguanas on San Cristobal start nesting. |
| April | 88°F | Warmest | Waved albatross begin their unique courtship rituals on Española. Giant tortoise eggs begin hatching. |
| May | 86°F | Warm | Blue-footed boobies start courtship on North Seymour. Sea turtle eggs begin hatching. |
Travel Tip: March and April are often the warmest months, making them perfect for beach lovers but physically demanding for long hikes.
The Cool Season: June to November
As the Humboldt Current sweeps up from Antarctica, it brings cooler air and nutrient-rich cold water to the Galapagos Islands. The Galapagos’ cool season is often called the Garúa season, named after the mist that settles on the highlands.
Weather & Ocean Conditions
- Climate: Temperatures drop, making hiking much more comfortable than in the warm season. Daily highs are typically between 72-79°F. Skies can be overcast or gray, particularly in the mornings.
- Water: The water temperature drops significantly. Snorkelers will almost certainly need a wetsuit (often provided by tour operators).
- Seas: The ocean becomes choppier during these months. If you are prone to seasickness, you may prefer a land-based hotel option or a larger, more stable vessel.
Wildlife Highlights
- Marine Explosion: The cold current brings nutrients that trigger an explosion of marine activity. This is the best time for underwater observation.
- Whales & Dolphins: Cetacean sightings are more common as they follow the food supply.
- Galápagos Penguins: These penguins are most active during this season, especially around Bartolomé and Isabela islands.
- Blue-Footed Boobies: Breeding is often in full swing, offering a chance to see their famous courtship dance.
| Month | Air Temp (Avg High) | Water Temp | Key Wildlife & Activities |
|---|---|---|---|
| June | 79°F | Cooling | Beginning of the cool season. Giant tortoises migrate to the lowlands. |
| July | 77°F | Cool | Sea birds are very active. Flightless cormorants court and nest on Fernandina. |
| August | 75°F | Cold | Galápagos penguins are most active and visible around Bartolomé and Isabela. Migratory humpback whales commonly sighted. |
| September | 72°F | Coldest | Peak of the cool season and roughest seas. Sea lions are very active. |
| October | 73°F | Cold | Blue-footed booby chicks can be seen almost year-round, but this is a good month for seeing them and their two distinct breeding cycles. Fur seals begin mating. |
| November | 75°F | Warming | Sea lion pups are leaving their mothers. Bigger waves on western islands (good for surfing). |
Travel Tip: September is generally the peak of the cold season with the most active marine life, but also the roughest seas.
