Boise, Idaho – Idaho residents heading into Memorial Day weekend should brace for an early taste of summer, with temperatures soaring near 90°F by Monday. Sunny skies will dominate the forecast starting Friday, bringing a dry, warming trend that could heighten fire concerns and impact road travel along I-84 through Tuesday.
According to the National Weather Service in Boise, Friday will be sunny with a high near 76°F, followed by steady temperature climbs into the upper 80s by Memorial Day. Winds remain light but dry, and the region’s low humidity could create elevated fire weather conditions through early next week. Saturday brings a high of 81°F, and Sunday surges to 87°F under continued clear skies.
If you’re hitting the roads, particularly I-84 or Highway 55, pack water and sun protection. Vehicle overheating becomes a risk in prolonged heat. Campers and hikers across the Boise foothills and central Idaho should follow fire safety protocols and monitor for any weekend fire weather statements.
Looking ahead:
- Monday (Memorial Day): Mostly sunny, high 88°F.
- Tuesday: Mostly sunny, high near 87°F.
- Wednesday: Hot and dry, high near 90°F.
- No storms or rain chances are expected through at least Wednesday, making for clear, if hot, conditions.
Expect updated fire weather alerts if winds increase. Check back for advisories, especially if you plan outdoor activities through midweek.
