Ecuador is a destination that can host visitors all year round.
The Andean highlands are very much an archetypal ‘four seasons in one day’ destination, and there are various micro-climates, though the altitude means that it is always cold at night. The Amazon region is hot and wet all year round. The Galapagos Islands have hot and sunny days with brief showers from January to June, the rest of the year tends to be drier but cooler and overcast.
Seas can be slightly rough in July and August.
