Weather in the Algarve is generally good throughout the summer, with a low average rainfall. Buildings are designed and furnished to be comfortable in hot temperatures, and may not be as well suited to wet or cold periods as houses in northern Europe.

Humidity can be a particular problem in countries where temperatures are usually high. In very wet periods, villas may give the appearance of being damp. However, as soon as the weather reverts to normal, and houses can be aired properly, any sign of dampness will quickly disappear.
