Local Climate & Pet Care

Winter

18°F to 45°F

Dec – Feb

Denver winters bring cold spells and snow, but sunny days often warm quickly. The high altitude means stronger UV exposure even in winter, so light-skinned pets may need sun protection. Paw wax helps protect against ice and road salt on city sidewalks.

Spring

30°F to 65°F

Mar – May

Spring in Denver is unpredictable, with possible snow one day and 70°F the next. Rapid temperature swings of 40°F+ in a single day are common. Cherry Creek and Chatfield dog parks become increasingly busy as the weather warms.

Summer

58°F to 90°F

Jun – Aug

Summers are dry and comfortable with low humidity, ideal for hiking and outdoor adventures. Always carry extra water as pets dehydrate faster at altitude. Watch for afternoon thunderstorms with lightning, especially if you are on exposed mountain trails.
