Ecuador Weather Guide

On the equator the sun rises at about six and sets at about six, every day of the year, give or take a few minutes. There is no long summer evening in Ecuador and no dark winter afternoon. What replaces the seasons is height: every thousand meters of elevation takes roughly six degrees off the temperature, and Ecuador spans sea level to well over five thousand.

What each region actually feels like

• Quito and the northern highlands, about 2,850 m. Daytime highs in the high teens or low twenties Celsius all year, nights close to single figures. Strong sun, thin air, rapid changes. Rain tends to arrive in the afternoon.
• Cuenca and the southern highlands, about 2,550 m. A little milder and a little drier than Quito, with the same daily swing.
• The paramo above about 3,500 m. Cold, wet, windy and exposed, with weather that turns inside an hour. This is the country's most underestimated environment.
• The coast, at sea level. Hot and humid all year. Wettest and brightest from about January to April, cooler and grayer from June to November.
• The Amazon, at a few hundred meters. Warm, humid and wet throughout, with no month that is reliably dry.
• The Galapagos, at sea level on the equator. Moderated by the sea. Warmer and calmer from about December to May, cooler and windier from June to November.

The equatorial sun is the thing people get wrong

Ultraviolet levels in the Ecuadorian highlands are among the highest recorded anywhere, because the sun is directly overhead and there is a kilometer less atmosphere above you than at sea level. Cloud makes very little difference to that. Sunburn on an overcast highland afternoon is one of the most common and most avoidable things that happens to visitors here.

Altitude and weather are the same subject

Cold, wind and thin air compound each other. Altitude sickness is a real risk in Ecuador, and Quito at about 2,850 m is where most visitors meet it first. Acclimatize before you go higher, never during. Give the first day to arriving rather than to doing anything, and treat a planned ascent of any of the volcanoes as a separate undertaking with its own preparation.

Reading a forecast here

A national forecast for Ecuador is close to meaningless. A forecast for a named town at a named altitude is useful. If you are moving between regions in a single day, which is easy to do, expect the weather to change completely rather than gradually.
