Adventure Weather Forecasts
Plan your next adventure with expert-level weather data that’s easy to use.
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 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.
Industry First Know Trail Conditions In Advance
We use recent weather conditions to estimate if the trail is muddy, a little wet, or dry, and we update this every hour. But don’t take our word – we offer one-click access to a visual history of precipitation and temperature during the past 24 hours so that you can make your own call.
High-Resolution Maps
We make it easy (and beautiful) to see if there is precipitation and wildfire smoke heading toward your favorite mountain, or if there is snow cover nearby. And take a peek into the future with our 18-hour forecast animations for precipitation, wildfire smoke, and temperatures.
