Description

OpenSummit is your trusted source for the best mountain weather forecast, high-resolution map overlays, and trail conditions information.

Conveniently displayed on your iOS device, find the latest 5-day hourly forecast for your favorite locations, receive estimated trail conditions, and view our high-resolution maps, all at your fingertips.

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.

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.

All-Access Features Include:

• 5-Day Hourly Forecasts
• Estimated Trail Conditions
• Wildfire Smoke Forecast
• Current & Forecast Radar
• Estimated Snow Depth Map
• Temperature Forecast Map
• OpenSnow All-Access

Carbon Removal 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.

Indispensable App for Hikers

I hike or summit peaks in Colorado year-round and this is my go-to app for planning and making sure I don’t get into dangerous or unpleasant weather situations. I love the five-day layout that color codes each day by the forecasted weather so I can tell at a glance when to plan my hikes. If I am going on a day of marginal weather, the hourly forecast has proved accurate and helpful to time my start and finish to avoid severe weather. I am impressed at how many peaks are covered by the forecast and always find one that is where or near I am going. This is a must-have app for any serious (or even casual) Colorado hiker.

Right on and that's our goal, to help you at-a-glance figure out the best days, then dial into the hourly details as your hike/adventure gets closer. -JOEL

Do not get this app!

It’s rare that I am so angry that I feel the need to write a negative review but I have to comment. This is a standard weather app that gives basic information provided by the NOAA. The free version gives very little of this information and only for some trailheads and peaks. I purchased the all access subscription and found it to have the same information you can get for free with a slightly prettier presentation. DEFINITELY not worth $20! I went back and reread the glowing over the top reviews. They read like absurd marketing language. I am amused at the thought of the developers writing reviews to themselves and then answering them. This is not my beef. I tried to find the toggle to stop auto renewal that they claim exists but doesn’t seem to. I tried to downgrade to the free version but the button on the website to do so is nonfunctional both on my phone and desktop. I have emailed the company with no response.

Developer Response ,

Hello and thank you for your review. We're so sorry to hear that you aren't finding OpenSummit useful. With the free version of the app, you receive 2-day hourly forecasts for over 1,500 mountain locations in the US. With the All-Access upgrade, you receive 5-day hourly forecasts, estimated trail conditions, current radar, 18-hour forecast radar, 18-hour forecast wildfire smoke maps, 18-hour forecast temperature maps, a current snow depth map, and unlimited access to our winter service, OpenSnow with the same login information. Compared to other standard weather apps, OpenSummit tells you if a trail is dry or wet based on recent weather trends, provides at-a-glance risk assessment about rain, lightning, and wind, and allows you to track smoke from wildfires, and forecast this smoke for the next 18 hours. These are features that we believe can't be found on any other weather app. We read and respond to every review and email so please send an email to hello@opensummit.com and we'll solve any issues that you're having right away. Thank you so much! -SAM

The best tool for planning my summits

Having the membership and ability to see lightning forecasts 5 days in advance on big peaks has changed how I can plan and increased the number of summits I completed last year! I didn’t even realize I also had access to Open Snow which was such a bonus for planning which ski resort to visit as well and when to request a day off more than just the night before when it’s dumping. The BEST app for a Coloradan Outdoor Enthusiast. The apps are very easy to use and to set up how you like.

Wow, thank you so much for this review! Have a great summer! -SAM
