Seattle vs. Portland Weather: A Detailed Comparison
Seattle and Portland, two major cities in the Pacific Northwest, are often compared, and their weather is a significant point of interest. While both cities experience mild, wet winters and warm, dry summers, there are subtle differences in rainfall, sunshine, and temperature that can influence your preference.
Average Temperature and Rainfall
Both Seattle and Portland enjoy a relatively moderate climate, thanks to their proximity to the Pacific Ocean. However, rainfall patterns differ slightly. Seattle tends to receive slightly more overall rainfall than Portland, although both cities are known for their persistent drizzle rather than heavy downpours. Summers in both cities are typically dry and sunny, with average temperatures in the 70s Fahrenheit (around 21-26 degrees Celsius).
Winter Weather: Rain, Clouds, and Occasional Snow
Winters in Seattle and Portland are characterized by frequent rainfall and overcast skies. Temperatures rarely drop below freezing for extended periods. Snowfall is infrequent and usually light, though occasional winter storms can bring heavier snow accumulations. Both cities are well-equipped to handle snow, but travel can be disrupted during significant snow events.
Sunshine Hours and Cloud Cover
A common complaint about both Seattle and Portland is the lack of sunshine, especially during the winter months. Seattle averages slightly fewer sunny days per year than Portland. However, the difference is not dramatically significant. The cloud cover is pervasive from late fall through early spring, which contributes to the perception of gloominess.
Summer Differences
Summers in Seattle and Portland are generally warm and dry, with sunny days becoming more common. Temperatures typically range from the 70s to low 80s Fahrenheit. Portland, being slightly further inland, might experience slightly warmer temperatures than Seattle during the peak of summer. Wildfire smoke can affect both cities during late summer due to wildfires in the region.
Microclimates
It’s important to note that both Seattle and Portland contain microclimates, meaning that weather conditions can vary significantly within relatively short distances. Proximity to the Puget Sound in Seattle or the Cascade Mountains in Portland can influence local temperature, rainfall, and wind patterns. For example, areas closer to the water might experience milder temperatures and less snow during the winter. You can read more about the Climate of the Pacific Northwest at Wikipedia.
