The pacific northwest is located in the usda plant hardiness zones 7 through 9 and in the ahs heat zones 1 through 6. Stretching over a long expanse of territory, the Pacific Northwest climate is influenced by the Pacific Ocean and the North American tectonic plate system.
This map shows the distribution of heat zones in the United States. The map is based on data from the National Oceanic and Atmospheric Administration’s (NOAA) National Climatic Data Center.
