Boise, Idaho – A summer heat wave settles over Boise as temperatures soar past 90°F for another weekend, creating safety concerns for outdoor plans and road travelers.
According to the National Weather Service, Boise residents should brace for sunny, hot conditions starting Saturday, July 26th, with highs near 93°F and barely a cloud in sight. This early surge of late July heat is expected to persist through Tuesday, when Boise could see the thermometer spike to 100°F. Local agencies are advising residents to avoid strenuous outdoor activities during peak afternoon hours, hydrate frequently, and check on vulnerable neighbors. Travelers on I-84 and Chinden Blvd. should also be mindful of heat-related vehicle stress, especially with traffic expected to increase this weekend.
Saturday’s forecast calls for blazing sun and little wind relief across Ada County, pushing air conditioning demand higher and heightening wildfire risks in dry grasslands around Boise and Meridian. Overnight, temperatures will only dip to the mid-60s, providing limited cooling for homes and outdoor events. While a brief, slight chance of thunderstorms may skirt the area late Saturday, most will see continued dry skies.
Looking ahead, Sunday brings more sunshine with highs near 94°F. Monday will heat up further, approaching 97°F, before Boise faces a scorching 100°F on Tuesday, July 29th. By Wednesday, the heat slightly tapers but remains intense, with highs holding near 99°F through Thursday. Emergency management teams stress the importance of staying indoors, limiting afternoon travel, and ensuring pets and livestock have plenty of water.
