Lleida, the capital of the province of the same name in Catalonia, sits in the central Catalan depression at 155 metres above sea level, on the Segre River plain before its confluence with the Ebro. Its climate is semi-arid continental Mediterranean, with very hot summers and cold, foggy winters. The annual average temperature is around 15 °C, with summer highs exceeding 34 °C and winter lows frequently dropping below 0 °C.
Annual rainfall is scarce, barely 369 mm, making it one of the driest provincial capitals in Spain. Fog is the most characteristic weather phenomenon of Lleida, occurring very frequently between November and February due to thermal inversións in the Segre depression. These fogs can persist for weeks and keep maximum temperatures below 5 °C. Frost days exceed 50 per year. Summer thunderstorms are occasional and can be accompanied by hail.
