Description: Mt. Everest Weather forecasting for climbers. Custom forecasts to help time the right weather window. We have been forecasting since 2003.
From Alan Arnette Everest Blog “Lukas Furtenbach, the founder of Austrian-based Furtenbach Adventures, said they had had a -22F summit day with 25 mph winds but no frostbites in their team. He noted that most of the frostbite could have been avoided by using professional weather forecasting services and avoiding risky weather windows, “I have to say that our weather forecast from Michael Fagin (Westcoast Weather) this season was exceptionally accurate, especially summit wind speeds.”
Mount Everest is located in the normal elevation in which the jet stream is located so winds during much of year exceed 80 mph (128 km/hr.). Remember, hurricane force winds are at 74 mph (118 km/hr.) or greater. During the winter months the subtropical jet is aimed over Mt. Everest bringing these strong winds. If the polar jet, which is normally located close to 50 degrees latitude, dips to the south and merges with the subtropical jet, Mt. Everest and the rest of the Himalaya can get some extreme winds of
The big question for climbers of Mt Everest and the other major 8000 meter (over 26,400’) peaks is the timing of the weather patterns which bring reasonable winds for climbing (usually 25 mph or less). Starting in March and April we begin to see a minor reduction in the winds, but this is more likely in May. What usually happens in May is the polar jet begins to shift to the north and the subtropical jet starts to weaken. Sometimes there is short window early in May of reasonable winds. However, it is more
