Boise in August
Great time to visit
August matches July's intensity with blazing heat and peak tourist activity. The month offers some of the year's best festivals, but you'll pay premium prices and battle serious crowds.
Weather
August continues July's heat pattern with scorching afternoons and warm evenings perfect for outdoor dining. The mercury regularly hits 32-35°C during peak afternoon hours. Late in the month, you might catch the first hints that autumn isn't far off, especially in early morning temperatures.

All Months
May through October gives you the best of Boise's outdoor scene. Summer temperatures hit the mid-80s, perfect for floating the Boise River or hiking in the Foothills. But here's what locals know: September and early October are magic. Crowds thin out, temperatures drop to the comfortable 70s, and fall colors light up the cottonwoods along the river.
Winter brings snow to the mountains but not much to the city itself. Boise sits in a high desert, so you get cold, clear days perfect for exploring downtown or hitting up Bogus Basin ski area, just 16 miles from downtown. Hotel rates drop significantly December through March.
Avoid late July and August if you don't handle heat well. The high desert sun is intense, and afternoon temperatures can push into the 90s. Spring comes early here — by April you're seeing wildflowers in the Foothills and comfortable hiking weather returns.
