Vigo has a warm-summer Mediterranean climate (Köppen Csb): dry, sunny summers and mild, wetter winters.
The warmest month is August, when afternoons average 25° and nights 16°. January is the coolest month, with highs of 13° and lows of 7°. The difference between the warmest and the coolest month is about 10°, a small seasonal swing typical of places tempered by the sea.
About 1,714 mm of precipitation falls in an average year. January is the wettest month (187 mm, 16 wet days) and July the driest (38 mm, 6 wet days). Cloud cover ranges from 20% in July to 42% in December.
