OpenSummit is your trusted source for the most accurate weather forecast, high-resolution map overlays, air quality, and trail conditions information.

"From smoke to lightning, trail conditions to wind chill, OpenSummit is the one-stop-shop for planning my summer adventures." - Cody Townsend, Pro Athlete

Conveniently compare forecasts on a single screen, plan summit days with 5-day hourly forecasts, view estimated trail conditions, track storms (and wildfire smoke) with high-resolution maps, and stay safe in the backcountry with offline maps.

Forecasts for Mountains, Not Nearby Towns

Most weather apps only provide forecasts for nearby towns. With OpenSummit, you'll receive hourly forecasts for the actual mountain location (and elevation). This means that our precipitation, lightning, temperature, and wind forecasts are more accurate when planning your next mountain objective.

Plan Summit Days With Confidence

Choose the safest day and time for your adventure. We color-code detailed hourly data so that you can quickly find your best weather window. 5-day hourly forecasts include the chance of precipitation, chance of lightning, temperature, wind speed & direction, and cloud cover.

Know Trail Conditions In Advance

Before heading out on your next hike or mountain bike ride, check our estimated trail conditions. We use recent weather conditions to estimate if the trail is snow-covered, muddy, a little wet, or dry, and this information is updated every hour.

Track Storms & Air Quality In High-Resolution

We make it easy (and beautiful) to see if there is precipitation and wildfire smoke heading towards your location, and if there is snow cover, lightning, or poor air quality nearby. You can also take a peek into the future with our 2-day forecast animations for precipitation, wildfire smoke, cloud cover, wind gust, and temperature.

Save Offline Maps
