Whatcom County is heading into a warm stretch this weekend, with a heat advisory in effect for the foothills and valleys of the North Cascades beginning Sunday morning. A county-wide Stage 1 burn ban follows on Monday, June 15, running through September 15.
The Whatcom County Sheriff's Division of Emergency Management flagged the heat advisory in its Friday briefing. The advisory covers the foothills and valleys of the North Cascades and runs from 11:00 a.m. on Sunday, June 14, through 5:00 a.m. on Tuesday, June 16. Bellingham itself, situated along the western slopes closer to the bay, may see somewhat cooler temperatures than the inland valleys, but residents throughout the county should be prepared for elevated heat.
The Bellingham Fire Department issued its own reminder ahead of the warm weekend, urging residents to stay hydrated, seek shade during the hottest part of the day, and avoid strenuous outdoor activity when temperatures peak in the early-to-mid afternoon. The department specifically flagged two situations that can turn quickly fatal: never leaving children or pets in parked vehicles, and checking in on elderly neighbors or family members who may be more vulnerable to heat-related illness.
On Monday, June 15, the Whatcom County Fire Marshal's Office will implement a seasonal Stage 1 burn ban across the entire county. The ban runs through September 15, 2026, though the Fire Marshal's Office may escalate to Stage 2 or extend the ban if fire conditions worsen later in the summer. Under a Stage 1 ban, recreational fires and debris burning are prohibited throughout unincorporated Whatcom County. Campfires in designated recreation areas may also be affected, depending on individual land manager rules. Residents should contact Whatcom County's outdoor burning information line at 360-778-5903 for specific guidance on what is and is not permitted in their area.
The burn ban arrives as Bellingham and the broader region enter what is typically the driest and most fire-prone part of the year. Eastern Whatcom County, including the foothills and forested areas around the Mount Baker-Snoqualmie National Forest, faces meaningfully higher fire risk as vegetation dries out through June and July. The Stage 1 ban is a standard seasonal measure the county uses to reduce human-caused ignitions before conditions deteriorate further.
This weekend's heat is not expected to reach the extreme levels seen during the 2021 heat dome that broke temperature records across the Pacific Northwest. Still, temperatures in the upper eighties to low nineties are forecast for parts of Whatcom County, which is warm enough to pose real risk for vulnerable residents and for anyone engaged in prolonged outdoor activity without adequate hydration and shade.
Residents can sign up for Whatcom County emergency alerts through WhatcomReady to receive notifications if conditions change or additional restrictions are put in place this weekend. For heat-related illness, dial 911 in an emergency or contact the Poison Control Center at 1-800-222-1222 for guidance on heat exhaustion symptoms.
Looking ahead to next week, temperatures are expected to moderate after Tuesday, with more typical June weather returning to the region. The burn ban, however, will remain in place through the summer season regardless of day-to-day conditions.
