The weather in Ecuador is made up of many different climates and micro-climates, as the weather may vary according to the geography of the country rather than depend on any actual seasons. In Ecuador there are 9 definitive climates. These consist of one dry climate, three tropical climates, a wet climate, the monsoon area and the Savannah. There are also three meso-thermic climates including wet, semi-wet and dry; the paramo, alpine tundra and the ninth climate that is usually included is that of the Galapagos Islands.

The temperatures in the Galapagos and the coast of Ecuador are affected by the currents of the Pacific Ocean. These currents cause hot, wet and humid weather between the months of January and April; this is when torrential downpours occur and these can have a negative effect on communications. During these months the daytime temperatures average around 30°C and the locals spend a lot of time on the beach. Between the months of May to December, there are cooler currents coming from the South which keep the temperatures a few degrees lower. During this period there is little rain but there are long periods when it is overcast, particularly in July and August.

The dry season for the higher ground is from June until September, along with another short dry season around Christmas time. April is the wettest month, with rainfall nearly every other day. Daytime temperatures in the capital of Quito reach on average a high of 21°C and a low of 8°C all year round.

In the Oriente region there is quite a bit of rainfall in most months and this is mostly in the later half of the day. The driest months for this region are August and December until March and the wettest months are from April to June, with some variations regionally. This area can reach temperatures which rival those on the coast.

Climatic variations depends more on altitude than the time of year. The four distinct seasons that most expats will be used to do not occur in Ecuador. There are two air currents that cross Ecuador, one is a cold and dry current which comes in from both hemispheres, and this is mainly felt in the mountainous region from the months of May to October. The other current is warm and humid which comes from the tropical zones that which can be experienced from November through to April.
