Although the islands are fantastic all year round, the best time to visit Galapagos runs from December to May. The season offers lush vegetation, calmer waves, and warm, sunny weather with occasional rain. This period is perfect for snorkeling and exploring Galapagos wildlife. Just imagine yourself seeing fantastic manta rays, green turtles, and marine iguanas!
The dry season from June to November boasts active marine life and comfortable weather conditions. The drawback is a rougher sea. Extended rainfall is also prevalent, so pack an umbrella, just in case.
Generally, no matter when you visit the islands, they are spectacular. Just keep in mind that the government confines the number of tourists permitted on the Galapagos, so book in advance to be safe.
