“Weather forecasting for the mountains takes extra focus, analysis, and precision, which is exactly what OpenSnow provides.” – Cody Townsend, Pro Athlete

View Forecasts Anywhere on Earth

Our weather forecasts are available for any location on Earth, instantly. This means that you can view our weather forecasts for your favorite ski resort, backcountry ski location, camping destination, London, Denali, and yes, even for your home neighborhood or current location. Save up to five custom locations to view on your "Favorites" screen for quick and convenient access to the latest 10-day weather forecast and estimated snow report.

Read Daily Analysis From Local Forecasters

Now you have a personal weather forecaster guiding you to the best conditions. Our local experts write a new “Daily Snow” forecast each day for regions around the US and Canada. Instead of spending hours sifting through weather and snow data, you can now get the inside scoop in just a few minutes.

Track Storms With High-Resolution Maps

We make it easy to see if there is snow heading toward your favorite mountains, along with how much snow fell over the past 24 hours, season-to-date, and snow depth. You can also view 2-day forecast animations for wildfire smoke, wind gusts, cloud cover, and temperature, live and forecast radar, as well as the latest avalanche forecast and active fire perimeter map for the past 7 days.

Compare Essential Powder Chasing Tools

Finding the deepest snow at the right time requires data, skill, and a bit of luck. We can’t help with getting lucky, but we can provide everything else, including outlooks from multiple snow forecast models, hourly details, mountain cams, and the latest snow reports.

Ratings and reviews

The weather forecasts are pretty inaccurate, but help give you a very vague idea of the conditions. Do NOT prepare for a trip expecting it to be within 10 degrees. The full website is nice, but the app is pretty much useless because it only does peaks. You can use Opensnow for any location, but that still makes the Opensummit app pointless unless you're going to an actual peak.

Upgraded to 5*. The best, most useful and uniquely valuable apps I've ever used! Support response is very quick, and feedback & requests for enhanced features (incl. adding locations, campgrounds, etc) are taken seriously and with fast response. Graphs are superb with clever weather variable option buttons below the graphs, making for lots of info. available at a glance with minimum scrolling. My only feature wish is to have forecasts extend to 7 days-paid ver.

Just installed today and have been a longtime user of opensnow. Love the clean design of this app just like their other app. Makes checking weather on my favorite peaks simple. The only issue so far is the app goes offline whenever I stop using it, though my phone hasn't lost network connectivity. The only way I have found to resolve it is to shutdown the app and restart it. Once this bug is fixed, I'd give it 5 stars.
