## Geography and climate

Jingyu is located in southern Jilin and the northern part of Baishan City on the upper reaches of the Songhua River amidst the western periphery of the Changbai Mountains. The bordering county-level divisions are Fusong County to the east, Jiangyuan District to the south, Huinan to the west, and Huadian to the north. Its latitude ranges from 42° 06' to 42° 48' N and longitude 126° 30' to 127° 16' E. The average elevation in the county is 775 metres (2,543 ft), though the county seat is only at 549.2 m (1,802 ft).
Jingyu has a monsoon-influenced, humid continental climate (Köppen Dwb), with long, bitterly cold winters, and short, warm and rainy summers. Spring and autumn are short with some rainfall. The monthly 24-hour average temperature in January is −17.0 °C (1.4 °F), and 21.0 °C (69.8 °F) in July, and the annual mean is +3.9 °C (39.0 °F). The mountainous location means that diurnal temperature variation is large, reaching 17 °C (31 °F) in winter, but precipitation is enhanced: the annual average is 779.5 millimetres (30.7 in), with more than 80% of it falling from May to September.
