BOISE, Idaho – A bright stretch of early October sunshine will make this week one of the best for fall activities across the Treasure Valley. After a crisp 45-degree start Sunday morning, clear skies and steady warming will return, setting the stage for mild afternoons ideal for pumpkin patch visits, leaf-viewing drives, and outdoor events.
According to the National Weather Service in Boise, temperatures will climb steadily each day, reaching the lower 70s by Tuesday and mid-70s by midweek. Winds will remain light, and no rain is expected through Thursday, offering safe travel conditions along I-84 and regional routes. The clear, dry pattern follows a cool start to the weekend and signals one of the last extended warm spells before late-October cold fronts.
Residents should plan to enjoy outdoor decorating, hiking, and early Halloween prep before cooler air arrives late in the week. Light winds from the northwest may bring slight morning chill, but daytime warmth will quickly return.
The NWS advises continuing to water gardens and new plantings as the soil remains dry despite cool mornings. Campers and parkgoers should also note that high fire danger remains possible in dry grass areas due to the ongoing stretch of sunshine and light wind.
