Portland and Vancouver could see this year’s hottest temperatures this weekend

People across the Willamette Valley could see record-breaking heat this weekend, when temperatures are expected to climb into the triple digits.

The National Weather Service has issued an extreme heat watch from 11 a.m. Sunday morning through Monday evening for the Portland-Vancouver metro area, parts of the Columbia River Gorge, and east Clark County.

Starting Saturday, forecasters say, temperatures could reach into the 90s and could climb above 100 degrees on Sunday and Monday. Some areas could see temperatures as high as 105 degrees.

David Bishop, a meteorologist with the National Weather Service, said people should avoid going outside if possible and instead find an air-conditioned building to cool off.

“Making a plan to say, like go visit the library or go to the mall and walk around or something along those lines, ways to get out of the heat or the outside during the very hottest parts of the day, that’s always a good idea,” he said.

Bishop also recommends checking on vulnerable neighbors and family members who are more sensitive to the heat – especially since overnight temperatures are expected to only fall into the mid-60s, and could be higher.

Dangerously hot temperatures can cause a range of heat-related illnesses, which can be fatal, and the risk rises when people are unable to cool off overnight. Officials urge people to stay hydrated by drinking plenty of fluids.

According to Bishop, this weekend’s heat has the potential to break records across the Portland-Vancouver metro area.

“We’ve had like a couple days here and there that have broken into the low 90s,” he said. “But nothing in the triple digits for 2026.”

This region doesn’t typically see triple-digit temps until around mid-July, Bishop said. The earliest Portland has seen 100-degree heat was in May 1983.
