Dalian has a monsoon-influenced humid continental climate (Köppen Dwa), characterised by humid summers due to the East Asian monsoon, and cold, windy, dry winters that reflect the influence of the vast Siberian anticyclone. Except for winter, the city experiences a one-month seasonal lag due to its position on the Liaodong Peninsula. Average temperatures range from −3.9 °C (25.0 °F) in January to 24.1 °C (75.4 °F) in August. Annual precipitation averages 602 millimetres (23.7 in) but is heavily concentrated in the summer months and can vary greatly from year to year. Due to the coastal location, the mean diurnal temperature variation annually is small, at 6.75 °C (12.2 °F). Sunshine is generous year-round, with an annual total of 2740 hours. The annual mean temperature is 10.9 °C (51.6 °F)
