Boise weather facts every pet owner should know
- July highs in Boise average 92.7F, above the 90F danger line for dog walks, so high summer means dawn outings and paw checks on sun-baked pavement.
- Boise's dry climate gives big daily swings: even in July, lows average 61.9F, so early morning walks are comfortable even when the afternoon will be dangerous.
- Snow is modest for the Mountain West, about 17.6 inches a year with December's 5.6 inches the peak, so most Boise dogs need paw care for only a few stretches each winter.
- Boise sits where the high desert meets the foothills of the Rocky Mountains, and its records span 111F to -28F, so trail dogs here should be conditioned for both extremes.
