Pacific Northwest Climate Maps

See how climate varies from time to time and place to place across the Pacific Northwest.

These maps show climate anomalies – the changes in climate – associated with different patterns of climate variability compared to average conditions during 1915-2003. To see a map of historical average conditions for any climate parameter, choose “all years” in section 1b.

Changes in regional climate projected to result from global warming will be available soon.

The data are derived from historical climate measurements, global climate model simulations, and a spatially-distributed hydrology model. More information about the datasets and methods used to produce these maps.
