Paris has a typical Western European oceanic climate (Köppen climate classification: Cfb?) which is affected by the North Atlantic Current. The overall climate throughout the year is mild and moderately wet.[72] Summer days are usually moderately warm and pleasant with average temperatures hovering between 15 and 25 °C (59 and 77 °F), and a fair amount of sunshine.[73] Each year, however, there are a few days where the temperature rises above 30 °C (86 °F). Some years have even witnessed some long periods of harsh summer weather, such as the heat wave of 2003 where temperatures exceeded 30 °C (86 °F) for weeks, surged up to 39 °C (102 °F) on some days and seldom cooled down at night.[74] More recently, the average temperature for July 2011 was 17.6 °C (63.7 °F), with an average minimum temperature of 12.9 °C (55.2 °F) and an average maximum temperature of 23.7 °C (74.7 °F).
Spring and autumn have, on average, mild days and fresh nights, but are changing and unstable. Surprisingly warm or cool weather occurs frequently in both seasons.[75] In winter, sunshine is scarce; days are cold but generally above freezing with temperatures around 7 °C (45 °F).[76] Light night frosts are however quite common, but the temperature will dip below -5 °C (23 °F) for only a few days a year. Snowfall is uncommon, but the city sometimes sees light snow or flurries with or without accumulation.[77]
Rain falls throughout the year. Average annual precipitation is 652 mm (25.7 in) with light rainfall fairly distributed throughout the year. The highest recorded temperature is 40.4 °C (104.7 °F) on July 28, 1948, and the lowest is a -23.9 °C (-11.0 °F) on December 10, 1879
