Climatological Data - West Central
The west central region of Alaska encompasses the region of maritime influence from the Bering Strait southward to cover most of the Yukon-Kuskokwim Delta. The coast is bordered by sea ice in the winter, and the coastal areas to a considerable distance inland are treeless and (at least in the delta area) dotted with small lakes. Although the mean annual temperatures are similar to inland sites at the same latitudes, the seasonal range of temperatures is much lower and the winds are much higher.

Similar to the Arctic Division, there are very few homogeneous long-term climate stations in the West Central; Bethel, Koztebue and Nome the notable exceptions. Historically, there were a numer of stations in operation along the many river villages in this area, as well as the Bering Sea coast.
