what to expect

mountain weather

My forecasts help put Teams on summits. My track record over the last 10 years is proof with over 50 world-wide mountaineering & skiing expeditions under my belt and a high summit success rate. 

"The window you suggested worked out perfectly and was our only real option to get down. Seriously, you made the difference."
-Darrin Nicholas, Mountaineer, Summited Point 11,300 Alaska

accurate forecasts

"Tomer is simply the only one I would ever trust or use for weather forecasts on a big mountain expedition."
-Ryan Kushner, Mountaineer, Summited Gasherbrum II 2016.

Why you need it

Standard service includes a daily forecast update with the following details:

  • Summit Windows
  • Wind
  • Snow
  • Temperature

Each forecast update goes up to 8 days into the future - on occasion 10 days depending on model performance.


As the summit window approaches I will send a second daily forecast update.  This helps communicate any forecast changes and how to adjust plans.   


Standard service also includes answering any questions you might have while on the mountain.  


I support both Delorme InReach and Satellite phone communications.

apps leave you flying blind

Having a bona-fide meteorologist with a trained eye is critical to success.  It's about seeing what's coming, where the opportunities lie, identifying risk, measuring the quality of data, making sure the data is current, and then communicating effectively to the team on the mountain.  

Teams that use my weather forecasts lower their overall risk and reach the summit more often.

Teams that use my forecasts are able to plan 8 days in advance (up 10 days on occasion).  This includes summit day, high camp rotations, and gear needs.

Teams that use my forecasts are more confident with peace of mind, and often spend less time on the mountain.

EXAMPLE, Denali, AK: Worst weather on Earth.  But, in my opinion forecasts from the NPS/NWS & Mountain-Forecast can't be trusted on Denali.    

Apps and certain websites can't be trusted in life and death situations.  Why?

  • They are automated forecasts straight off a server.
  • No human interaction to check quality control such as accuracy, initialization, timeliness.    
  • Represents one run of a mystery forecast model not matched to the mountain you're climbing.  
  • Leaves you with 1% of the big picture.  
  • ​Apps can't answer questions.  No Q&A.
