There is no perfect time of year to to to Ecuador. The weather is so changeable over the course of the year that you can go at any time; it's just a question of luck! The country has two main seasons, a wet season and dry season, which vary according to region. The ocean currents around the Pacific coast and the Galapagos islands mean that they have similar climates: hot and humid from April to June, more agreeable from June to December. The Amazon is very humid all year round, whereas one can tour the Andes whenever one likes, the climate there being more bearable and the heat a little less tropical.
