May outlook: Trending warmer with a healthy amount of rain

Last month was the third warmest April on record, and 2023 is the warmest year on record to date in Washington.

May — the transition month between spring and summer — can take on different flavors. Sometimes, it’s more summerlike — as in 2018 and 2019. But, in cooler years, such as 2016, 2017 and 2020, spring has a harder time letting go. This year looks to offer both flavors with a chilly first week but then warmer weather to follow.

Our Washington May outlook calls for near to slightly above normal temperatures with near to above normal rainfall. We project the average temperature to range from 66 to 69 degrees compared to the 30-year normal of 67.2 degrees. For rainfall, we expect between 3.9 and 4.5 inches compared to the 30-year normal of 3.94 inches.
