Boise, Idaho – Summer starts early in Idaho as sizzling temperatures arrive Friday and intensify through the weekend, prompting safety concerns statewide.
According to the National Weather Service, Boise will hit 87°F on Friday, with a sharp jump to 93°F Saturday and a scorching 98°F by Sunday. The region will stay locked in this high-heat pattern through Monday, with calm winds offering little relief. Residents should limit outdoor activity during peak afternoon hours, hydrate regularly, and monitor vulnerable individuals, including children, seniors, and pets.
The rising heat also increases wildfire danger and road hazards. Travelers along I-84 should prepare for sun glare and watch for signs of tire blowouts on hot pavement. Northwest winds Friday and Saturday, while mild, could dry vegetation further — adding to fire concerns across Ada and Canyon counties.
