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

Get Outside With Confidence

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

Compare Forecasts

Finding the ideal location for your next adventure based on the weather can feel overwhelming. With OpenSummit, deciding where to go is easy. Compare the latest weather forecasts for your favorite locations on a single screen in just a few seconds.

View Estimated Trail Conditions

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 With High-Resolution Maps

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, as well as the global air quality forecast for the next 5 days.

Climate Change Commitment

To help mitigate the threat of climate change, we have committed 1% of our All-Access subscription sales to the direct removal of carbon dioxide from the atmosphere and its sequestration in secure, long-term storage.
