• Climate

Galicia is located on the Atlantic coastline in north-western Spain meaning that the climate is different from that of many other popular Spanish tourist destinations. The region experiences relatively mild and rainy winters and quite sunny summers with temperatures generally lower than found in other parts of Spain.

Spring can be wet and windy but also offers cooler walking conditions than the summer. Nights are often cold and rain is plentiful especially in mountain areas. August is the hottest month in Galicia with an average temperature of 18°C (64°F) but short heatwaves are possible during the summer, with highs around or above 30 °C (86 °F). At these times the wooded and shaded landscape of Galicia makes temperatures much more bearable than conditions in other regions of Spain. Early autumn offers more stable and cooler weather but later months also bring once again the risk of heavy rain.
