How to determine wind speeds for windchill effect?

[Kevin Rooney]

Sine you are looking for just an approximation of the wind and do not need something NIST traceable, I'd suggest a Dwyer Wind Meter . I have one I use for reporting the lake winds for sampling, it works great and won't break the bank. I found one on Ebay, that's going cheap. I found mine for $0.25 at a lawn sale (where else!), and so long as you keep it clean it'll function well. It's good from 0 to about 66 mph and does not need batteries.

I bought one of these several years ago at the Museum on the summit of Washington - about $13 if I recall. Have yet to actually use it though ...
