The Galapagos Islands are located at the Equator so there is not a lot of seasonal variation. Air temperatures tend to run in the 70s-80s year round, making the islands a great place to visit at any time. However, the month of December brings seasonal changes to the Galapagos. Here are a few highlights on what you can expect during a Galapagos tour in December:
Warm: Warmer season begins and temperatures average max. 80F / min. 70F.
Rain: Beginning of Galapagos' rainy-season and the landscape starts to green. Keep in mind, average rainfall during this month is still little more than 1 cm.
Sun: Start of the sunny-season. Expect around 4 hours of clear, sunny skies each day.
Water: Water temperatures start to warm up as the cold Humboldt current clears out. Water temperatures average in the mid 70s.
Wildlife: Green sea turtles begin mating; Giant tortoise eggs start hatching in the wild; and the first of the young Waved Albatross fledge.
