The area is home to long winters, and humid, somewhat hot summers, belonging to the humid continental climate regime (Köppen Dwa). Winter usually begins in late November and continues until the end of March (about 4 months), with the most severe cold only lasting for around three weeks in December, January or February. The coldest month, January, averages −7.4 °C (18.7 °F). Spring, though a period of quick warming, is delayed by one month compared to more inland parts of the province, and is somewhat dry until May. The heat of summer is somewhat moderated by the proximity to the ocean; the city's warmest month, August, averages 23.4 °C (74.1 °F), while Shenyang, inland and further north, averages 24.7 °C (76.5 °F). Precipitation is generous, too, further exemplifying the maritime influence.
For the city proper, the annual mean temperature is 8.94 °C (48.1 °F), and the total precipitation is 926 millimetres (36 in), but within the prefecture, annual means can be as low as 6.8 °C (44.2 °F), while precipitation ranges from 881.3 to 1,087.5 millimetres (34.70 to 42.81 in)
