Weather Planning
Understanding weather patterns is crucial for timing your trip right and staying safe on the trail.
Temperature Planning
Check both daytime highs and overnight lows. Mountain temperatures drop 3-5°F per 1,000ft of elevation gain.
Precipitation Patterns
Learn regional patterns—afternoon thunderstorms in Rockies, morning fog on coasts, monsoons in the Southwest.
Daylight Hours
Plan activities around available light. Summer offers 14+ hours; winter may give you only 9-10 hours.
Weather Window Tips

- Be flexible with dates when possible for optimal windows
- Always have a backup plan for weather changes
