Azores
Köppen classification

Under the Köppen climate classification, the eastern group (São Miguel and Santa Maria) is usually classified as Mediterranean while the central and western group (especially Flores and Corvo) is increasingly more humid subtropical and overall rainier because of the effects of the Gulf Stream. This stream has a large effect over the sea temperature which varies between 16 °C (61 °F) in February and March, and 23 °C (73 °F) in August and September, and increases earlier in the western group.

Salvador Rivas-Martínez data presents several different bioclimatic zones for the Azores. Seasonal lag is extreme in the low-sun half of the year, with December being milder than April in terms of mean temperatures. During summer the lag is somewhat lower, with August being the warmest month, though September is usually as warm or warmer than July.
