Though its islands can be enjoyed all year round, one of the best times to visit the Galápagos is during the warm (or green) season from December to May. This is the most popular time to visit with mostly sunny days, temperatures ranging from the 70s to the upper 80s, and typically calmer conditions at sea, which makes for excellent visibility for snorkeling and diving. The sometimes overlooked cool (or dry) season from June to November is also an excellent time to visit the Galápagos, with average temperatures still pleasant and topping out in the mid 70s, typically dry conditions and a surge in large marine life that make it an ideal time to spot dolphins and whales.
