Summers in Boise: What to Expect in 2025

If you’re thinking about moving to Boise or just planning a visit this summer, you’re probably wondering what the weather will be like. Summers in Boise are known for being warm, sunny, and perfect for outdoor adventures—but 2025 is shaping up to be a summer to remember.

Warm and Often Hot

Boise summers typically bring plenty of sunshine with daytime highs averaging in the mid-80s to low 90s Fahrenheit (around 29–33°C). July 2025, for example, is forecasted to have daily highs around 32°C (about 90°F), with nights cooling down to a comfortable 14°C (57°F). You can expect about 13 hours of sunshine per day, making it ideal for everything from hiking to dining al fresco.

However, recent years have seen some extreme heat waves, and 2025 may be even hotter than usual. Last summer, Boise experienced 20 days with triple-digit temperatures, including record-breaking streaks of days over 105°F. This kind of heat can make midday outdoor activities challenging, so locals often plan around the cooler mornings and evenings.

Occasional Showers and Thunderstorms

While Boise is generally dry in the summer, June and July can bring isolated thunderstorms and scattered showers, especially in the southern parts of the Treasure Valley. June 2025 is expected to have a few rainy days—around 3 to 8 days of light rain—helping to cool things down briefly and keep the landscape green.
