Pontevedra has a humid oceanic climate (Köppen Cfb). The average temperature is 15 °C (59 °F), with a daily average of 9.5 °C (49.1 °F) in January and 20.5 °C (68.9 °F) in July. These are unusually mild for a city so far north, and are due to Pontevedra’s proximity to the sea and to the moderating effect of the ria. Yet, like the entire Galician coast, Pontevedra is subject to occasional Atlantic storms in Winter. These are characterised by a quick drop in temperature, rain and gales.
Overall Pontevedra is rainy, especially at the end of autumn and winter, with an annual average precipitation of 1,700 to 1,900 millimetres (66.9 to 74.8 in), and around 134 rainy days per year. Summer is drier, generally speaking, but the odd heavy rainfall does happen even then
