A very detailed look at how complicated wind readings and forecasts are.

I like the girl, I thought her accent was Canadian, but must be American, non distinctive.
I can go to sleep now , knowing this.

Very distinctive - likely either Canadian or Minnesota just from the voice. The local maps used are for Toronto which is indeed, their home. :) The "ou" sound, like "out" is a key. 0:06

Great video. This should foster a lot of local discussion.

The other problem is that anemometers all seem to vary. I've had several over the (40!) years and they have all given different readings. I only really use them to determine if there is enough wind for my biggest kit or too much for my smallest.
I recently replaced my Skywatch which I have had for years with a Kestrel. With the Skywatch I know I can plane from 19 mph up on my Moo 66L & 4.7 and use my 3.4 up to about 32 mph. The Kestrel give lower reading and I can plane in 17 mph (not tested the upper limits yet) Which is more accurate? No idea.

So if equipment used by the forecasters has similar differences no wonder forecasts are always crap!

Several references have been made about her Nationality. Since she is wearing a tuque, aka a knitted winter hat, or beanie, a clear indicator that she is Canadian. The lack
of any visible Maple Leaf tattoos, and total absence Of any Tim Horton cups or donuts both lead me to suspect she is American.

Despite her entrancing accent and easy manner I sped through the latter half. Whilst she said forecast models are instantaneous windspeed not sure that is bad as I assume models as well as having spacial resolution have temporal i.e. they might run models every 5 minutes so that would give a 5 min average which they call instantaneous. Some forecast also give gusts. In my local beach you get half way between the forecast average and the gusts 90% of time which is OK if you know that. On another beach I get the average 50% and gusts 50%, again OK if you know that. So you leanrn what forecasts actually mean by experience, and if somewhere new as the locals. As for hand held meters I don't believe any of them, but again they can be handy at a new beach if alone and you have calibrated i.e. says 20 knots but really it is 15,
