In May, expect pleasant temperatures with little rainfall. It is generally a bit colder, and as the Galápagos Islands are approaching the dry season, it is the perfect time to travel if you are looking to escape the rain and heat of winter. There is also a lower degree of humidity than the rest of the year, with daily temperatures around 72-75°F. The waters become more refreshing as well, with sea temperatures around 72°F. 

Crowds & Costs

May is considered the "shoulder month" between the low and high season with fewer visitors than earlier in the year. The best time to avoid bigger crowds and higher costs are during the first two weeks of the month. Toward the end of the month, Galápagos Islands tends to attract more travelers, as schools start their summer breaks.

It tends to also get busier around May 24 when Ecuador celebrates the anniversary of the Battle of Pichincha, which is a public holiday. If the celebration falls during the weekend, you can expect the entire weekend to be more crowded. To find good deals on accommodation and flights, make sure to plan your trip at the beginning of the month and be flexible with your dates.

In May, the wildlife continues to be abundantly active, and you will get to see a lot of species across the Galápagos Islands. One highlight is the unique courtship dance between the blue-footed boobies, which you can witness on North Seymor Island, home to a colony of blue-footed boobies 

On Santa Cruz Island, you can spot young land iguana hatchlings, and on Fernandina and Isabela Island, penguins are in the middle of their nesting season. Visit Punta Cormorant on Floreana, Puerto Egas on Santiago, and in Gardner Bay on Española, where the Galápagos green sea turtle continues to hatch.

You will come across mating sea lions and new sea lion pups greeting the world. In the port of Puerto Ayora, Galápagos sea lions take their afternoon siestas on a bench rather than the beach. Some of the best spots to see these charismatic creatures are San Cristobal, Isla Lobos, Gardner Bay, Punta Suarez, North Seymour, Punta Vicente Roca, and Punta Espinosa.
