I bought an anemometer, used it once or twice, now I'm not even sure where I stashed it anymore.
These days I consult the local forecast, and UAV forecast. I know that windspeed will always increase with altitude. Combine this with a little common sense (ya, I know....) and you're good to go, or not.
