Keep in mind that what happens at 10 meters on top of the observatory tower is not what happens from 0 to 6 feet off the ground.

Unless somebody measured the wind speed with a handheld anemometer I'd cut their estimates by half or more to get the true wind speed.

Years ago I did many winter climbs with the guides from EMS and they seemed to be pretty accurate at assesing the true wind speed - at least more accurately than us amatuers. Bill O - you are right - most people grossly over estimate the wind speed let's say when they are on lion head - based on the summit report. From my experience - it's damn near unlikely that you can make substantial uphill progress in anything more than 50-60mph - standing erect at that speed on uneven, icy terrain is difficult at best - not to mention the inevitable gusts that will knock you off your feet. I've spent many nights in the obs and have been on the deck in 100+ - needless to say, I was unable to join the century club. One year I was on an overnight trip and the winds were 110+ in the morning and we had to wait it out to descend - we started out when it was down to around 90 as measured on top of the tower and as soon as we started descending down through the parking lot you could feel the speed dropping dramatically.

This question also depends upon one's definition of a hike. If someone considers a 15 minute walk around the parking lot a hike, then sure, 90mph is possible. But...if someone claims to have climbed UP from Lion Head to the Obs deck fighting a 90mph headwind all the way, then they are most definitely lying (or maybe just delusional).

Just gauging wind conditions for a summit attempt, President's Day weekend. We're going with IMCS guides. Trip report to follow.

Thanks for the info on the summit anemometer; still, we will be taking no chances.

I've been in pretty high winds on both Mount Pierce and Eisenhower. Walking was difficult, to say the least. With each footstep, once I lifted my foot off the ground the wind did it's best to blow me off balance and send me skidding down the icy trail. With my back to the wind each gust felt as though someone was literally trying to tackle me and take me to the ground. How high were these winds? I'd say 40- 45 MPH with 50-55 gusts, no more.

Somewhere there is a "rule of thumb" guide to judging wind speed. "At 5-10 mph leaves begin to dance. At 10-20 mph bare branches will bend...", and so on. I can't remember it all. Is this posted somewhere on the MWO website? I thought that's where I originally saw it.

Probably thinking of the Beaufort Scale (http://en.wikipedia.org/wiki/Beaufort_scale)

ahh. the wind aint blowin' till ya reach lions head,then it still ain't blowin' 90 m.p.h. strong but not 90 m.p.h. after lionshead in the garden you're in the lee . not until ya git to the top was it crankin'! people panic at lions head cause it's a little windy and they're afeared it'll be constant to the top, but they're mistakin'. same goes for edmunds col,people get there and the wind is a howlin',they panic and turn around instead of headin' up to jefferson. all ya hafta do is walk a little farther and the wind dies down. i've seen it happen many many times in both places.:D

Yep, that's the one. Very useful. It,s also true what Poster Boy says, many times you can stay in the lee and out of the worst winds.
