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

We send 1% of our All-Access sales to innovative projects that directly remove carbon dioxide from the atmosphere and ensure its sequestration in secure, long-term storage. This alone will not solve climate change, but it’s a start.
