The climate in Porto is typical of the Atlantic regions: damp but temperate, with colder evenings. It may rain quite a lot in Winter, but it rarely snows. The temperature never falls below 0 ºC. In Summer temperatures raise and the warmest months are June, July and August, when temperatures vary between 20 ºC and 35 ºC. September, October, April and May are intermediate, with periods of atmospheric instability: quite frequently foggy mornings are replaced by sunny afternoons, or rain showers alternate with periods of bright sunshine. You are therefore advised to bring some warm clothes for the colder days.
