“There’s simply no one else I’d trust. On G2, when everyone else’s meteorologist’s were telling them the window is closed and climbing season is over, Tomer found us one last window and a perfect summit day on G2.” – Ryan Kushner

“I paid professional meteorologist Chris Tomer to give me daily weather forecasts for Everest sent by satellite to my inreach. I’ve found having an accurate weather forecast is perhaps the most important element for success on big peaks like this, and Chris has also forecast for me for big peaks like K2 (2022) and Pobeda (2021).” – Eric Gilbertson

“Chris, thanks for the expert weather forecasts you provided for our expeditions to Alaska, Pakistan and Nepal!” – Chris Warner

“Chris’ forecasts on Denali were a huge factor in our successful 13-day ascent. We went up when other groups were going down, confident in an upcoming summit window, and found ourselves standing on the summit on a clear, calm day. His morning forecasts kept us plugged in and more frequent updates near our summit push helped us make crucial decisions about when exactly to move. Absolutely an integral part of our successful trip!” – Leo Franchi

“Yeah, Tomer saved my life once with his forecast.  I was trapped on the summit of Peak 11,300 in the Ruth a few years ago.  Zero visibility and we could not find our way down.  We kept getting into trouble trying to find the complicated exit.  We called him and he predicted a short seam of visibility so we hunkered down and like clockwork the visibility improved as predicted just enough for us to navigate around the cracks and cornices to find the traverse and then ridge down.  He’s helped us in Nepal, Peru, and Alaska.  His forecasts are way more accurate than you’ll get from the rangers.  The forecast posted at 14 Camp comes out of Fairbanks and is mediocre at best.  The cool thing with using Chris is you’ll get a jump on other teams.  My first time on Denali we were able to go up when everyone else stayed in camp due to the conflicting forecasts.  Chris’ was accurate and gave us a window to get up there. ” – Keegan Young

“Having an accurate weather forecast is one of my most highly valued tools when going on a serious mountain expedition. There’s no one I trust to provide a better forecast than Chris Tomer. He has a ton of experience with difficult forecasting for high peaks in remote areas, and it shows. I really enjoyed working with Chris during trips to the Alaska Range in 2021 and 2022. He’s super responsive and helpful, going above and beyond to assist our team with a safe and successful trip. I look forward to working with him again in the future.” – Iain Kuo, ski mountaineer, alpine climber
