Galapagos Month-by-Month

JANUARY

Beginning of the rainy season

Land birds start nesting, generally after the first rain

On Hood (Española) Island adult marine iguanas become brightly coloured (green & red and black)

The green sea turtles arrive on the beaches for laying eggs

Land iguanas begin reproductive cycle on Isabela Island

Both, water and air temperatures rise and stay warm until June

Ideal time for snorkelling


FEBRUARY

On Floreana Island greater flamingos start nesting

Bahama pintail ducks (Black-tailed pintail) start their breeding season

Nazca (masked) boobies on Hood are at the end of their nesting season

Marine iguanas nest on Santa Cruz Island

The water temperature reaches its highest at 25C (77F). This temperature remains constant until April

Very few penguins are sighted on Bartolome Island (most have followed the cool waters back to the west)

Nesting season of the Galapagos dove reaches its peak


MARCH

The rainy season reaches its highest precipitation (this does not mean it rains everyday)

Sporadic tropical rains, intense sun and hot climate. Air temperature can reach up to 30C (86F). Humidity is high.

Marine iguanas nest on Fernandina

March 21st, the beginning of the summer equinox signals the arrival of the waved albatross to Española.

Even the western islands have warm waters where snorkeling is excellent. Punta Vicente Roca (Isabela) can be an amazing site. Penguins still active in the water, next to tropical fish!

Some shores, especially those facing north, can receive heavy ocean swells coming from climatic disturbances off the Central American coast. These swells can make landing a challenge in such places as Puerto Egas, Gardner Bay, Bartolome

Snorkellers will remain long periods of time in the water.


APRIL

Massive arrival of waved albatrosses to Española. Amazing courtship starts.

End of hatching season of the giant tortoises

Eggs of green sea turtles begin to hatch

Eggs of land iguanas hatch on Isabela

Whilst the rains have ended, the islands remain quite green

Good visibility in the water for snorkellers

Along with May, April is one of the the best months in Galapagos (weather, animals, water temperature)


MAY

North Seymour's blue-footed boobies begin their courtship

Sea turtles are still hatching on Gardner Bay, Punta Cormorant, and Puerto Egas

Most of marine iguanas' eggs hatch from nests on Santa Cruz

Palo Santo trees begin to shed their foliage

Waved albatrosses on Española start laying their eggs

Ban-rumped storm petrels begin their first nesting period


JUNE

Beginning of the Garúa season

Giant tortoises on Santa Cruz Island migrate from the highlands to the lowlands in search of suitable nesting places

Beginning of the nesting season of giant tortoises

South east trade winds return. Currents become a bit stronger. Seas pick up in surge and wave action.

Males Frigatebirds display their magnificent red pouches on North Seymour.

Southern migrants have started their journey towards the north. Galapagos is a rest stop for such birds. Some species of cetaceans also follow this pattern of migration.

Some groups of Humpback whales that migrate up to equatorial latitudes along the coast of Ecuador, can reach the Galapagos too.

JULY

Sea bird communities are very active (breeding), especially the Blue footed boobies on Española. Flightless cormorants perform beautiful courtship rituals and nesting activities on Fernandina.

If you walk along the shores of Puerto Egas (Santiago Island) you could find American oystercatchers nesting.

Lava lizards initiate mating rituals until November.

Cetaceans (whales & dolphins) are more likely to be observed, especially off the western coast of Isabela.

Great month to see the four stages of nesting of Blue footed boobies: eggs, chicks, juveniles and sub-adults.

Water temperature does not reach more than 21C (68F)


AUGUST

Galapagos hawks court on Española and Santiago

Nazca (masked) boobies and Swallow-tailed gulls nest on Genovesa Island

The temperature of the ocean drops to 18C (64F), which obviously varies according to the geographic zones among the islands.

Migrant shore birds start to arrive, and stay on the islands until March

Giant tortoises return to the highlands of Santa Cruz

Oceans are quite choppy, currents at the strongest levels, surge can be expected along the shores that face west or south.

Pupping season (births) of sea lions has started. Western and central islands are common places for such sightings.


SEPTEMBER

Peak of the cold (garúa) season.

The air temperature reaches its lowest levels (19C-66F).

Galapagos Penguins show remarkable activity on Bartolome. Since May swimmers and snorkellers may see, at Bartolome, penguins active at the surface or torpedo-like while underwater.

Sea lions are very active. Females have reached estrus stage, and so harem-gathering males are constantly barking and fighting. Shore fighting is heavy. Western and central islands are the most active ones in terms of sea lions' activities.

Most species of sea birds remain quite active at their nesting sites.


OCTOBER

Lava herons start nesting until March

The Galapagos Fur Sea lions begin their mating period

Blue footed boobies raise chicks all over Española and Punta Vicente Roca (Isabela)

Giant tortoises are still laying eggs

Days are not always sunny. Garúa can be expected in most locations, except the western islands where most days have a misty start but after few hours of daylight it burns off

Sunrises in the west can be quite beautiful after the garúa covers only certain locations of the western volcanoes. Summits are clear, but low-lying fog covers the shoreline.


NOVEMBER

Pupping of sea lions continue.

Sea lions are sexually active on the eastern part of the archipelago.

Breeding season for the brown noddies

Some species of jellyfish can be seen around the islands. The genus Physalia is commonly seen floating around Gardner and Tortuga Islets. Some can also be seen stranded at the shores of the Flour Beach at Floreana.

Band-rumped storm petrels begin their second nesting period.

Seas are calm. South east trade winds have decreased strength. Water temperatures are slowly rising.

Generally great weather due to transition between one season and the next one

Good visibility for snorkellers.

Sea lion pups (especially at Champion Islet) play aqua-aerobics next to snorkellers. Most pups here are curious enough to nibble at fins of snorkellers. The average age of most pups is 3-4 months.


DECEMBER

Hatching of giant tortoise's eggs begins and lasts until April

Green sea turtles display their mating behaviour

The rainy season begins, all of the plants of the dry zone produce leaves. Galapagos becomes "green"

The first young waved albatrosses fledge

Great weather
