Here’s when Whatcom County may see triple-digit heat

Read Next

Unseasonably warm weather is expected across Western Washington next week, with an outside chance that temperatures will approach triple digits.

High pressure building over the Pacific Ocean means there’s a 50-50 chance of daytime highs above 85 degrees starting Tuesday, July 26, according to an online briefing from the National Weather Service in Seattle issued Tuesday, July 19.

“A significant ridge begins to build offshore Sunday and into early next week, a period of temperatures much above normal for much of the Pacific Northwest,” meteorologist Jake DeFlitch said in the online forecast discussion.

It’s still too early for a precise forecast, but temperatures almost certainly will top 80 degrees in Bellingham and Whatcom County, meteorologists said.

The average mid-July high temperature is 73, according to weather service records.

“Either way, temperatures will warm into the 80s on Monday, with hot temperatures possible the middle of next week, increasing heat risk concerns for much of the week across the area,” DeFlitch said.

People play in Lake Whatcom and relax on the beach at Bloedel Donovan Park Saturday, July 2, in Bellingham. Temperatures above 80 degrees are in the forecast next week for Whatcom County, and there’s a small chance the area could see highs near the triple digits.
