In Topic: gauging wind speed
01 March 2012 - 10:21 AM
I have an anemometer, but it no longer registers correctly. So, I am thrust back on my own rules of thumb. These work mainly on a beach, as you will see.
a. Do I feel wind on my back when I walk downwind? If so, the wind is 4-5 mph or more. If not, it is less than my walking speed and an ultra-light is suggested.
b. Walking upwind, does the wind feel stronger than when standing still? If so, it is probably less than 10 mph - I cannot feel the difference between say 8 and 12 mph easily.
c. On the beach, is the sand moving? Dry sand starts moving around 12 mph - break out the mid-vent.
d. If the whole sand surface seems to be moving, 18 mph and up - full vent weather.
e. You definitely will know when the wind is 20 mph and up. Little dunes and valleys start building around everything on the surface of the sand.
On grassy fields, if the surface starts moving, I would probably start praying and running like heck.
Actually, the real velocity of the wind is less important than whether it is ultra-light, normal, or vented kite weather. (The figures above are what I think I remember when the anemometer was working - I was quite accurate for a while, but now I'm probably quite far off the actual MPH.)
So, on the low end, I use the feel of the wind relative to my walking speed, and on the medium and high end, the movement of the surface of the dry sand. Wet sand (below the surf line) aught to stay in place.
