Averages are the 1991–2020 climate normals (NOAA National Centers for Environmental Information) for the station named on each page. Rain days = days with at least 0.01 in of precipitation. Daylight is computed for the middle of the month. Weather station used: PORTLAND INTL AP, OR US (NOAA station USW00024229), about 7 miles from central Portland, at 19 ft elevation. All figures on this page are that station's 1991–2020 normals.
Monthly weather summaries are historical averages for trip planning only — they are not forecasts, and the weather in any given month will differ.
