We know the question on your mind, Portlanders — when’s it going to get hot?
Thanks to the National Oceanic and Atmospheric Administration’s Climate Prediction Center, we know what temperatures and precipitation trends to expect in our city for June, July, and August. While exact weather conditions typically can’t be predicted more than a week in advance, here’s a seasonal outlook to help you prepare for what summer will bring.
Reminder: The first day of summer is Wednesday, June 21.
Think hot. This summer, Portland has a 33-40% chance of temperatures being higher than normal. El Niño (which brings warm air and drier skies) also started to show signs of emergence in May.
Expect slightly less moisture. Portland has a 33-40% chance of seeing below-normal rainfall totals this summer.
Hot on the heels of one of Portland’s warmest and driest Mays on record, the first week of June has already seen higher-than-average temperatures. Typically in Portland, June has average highs of 72° and lows around 48° — but we’ll likely see days that are hotter. On the summer solstice (AKA the longest day of the year), there will be a 5:21 a.m. sunrise and a 9:03 p.m. sunset.
July’s average temperatures creep up to highs of 81° and lows of 53° This is also the driest month of the year with an average of 0.3 inches of rain — of course, that may be less this year, given the NOAA predictions. Pro tip: July is also the month with the highest UV index in Portland, so remember to protect your skin.
The averages stay pretty consistent, with highs typically around 82° and lows around 55° — but again, be prepared for more above-82° days. In August, the average heat index is 84°, which means heat-related illness is likely if you spend too much time in the sun.
