Yesterday was a classic example how your sensors have been fairly inaccurated. At Coyote for over 30 minutes your sensors were reading 20+ mph... In reality it was probably 12 on the water. I saw numerous people rig small based on your sensor readings, shaking there heads and going out. They all ended up swimming or slogging in.

Hi Willy,

Thanks for the feedback. While we strive to provide the most accurate wind data possible, quite often sensor readings will not reflect exactly whats on the water. Our sensors are a *good indication* of what its doing on the water, but nothing beats being there and using old fashioned methods like looking for whitecaps, checking what size sails other people are rigging, etc. The sensors should help you decide where to go, but once youre at the beach, your eyes are the best sensor.

Beyond that, each individual sensor location generates its own quirks - for the details on a particular sensor, click on the local info link on the left-hand side of any current wind webpage. Within that page there is a sensor notes section describing more-or-less how to use that particular sensor. Coyotes local info page is <a href=http://www.iwindsurf.com/windandwhere.iws?regionID=11&geographicalAreaID=28&siteID=211&Isection=Local+Info>here</a>

I knew people who drove to the water and rigged based on TV or NOAA FORECASTS, even though they KNEW our forecasts (Rocky Mountain states)were sometimes off by an entire DECIMAL POINT, let alone a measly 10-20-30 mph.

EYES, guys ... EYES. The meters tells ya whether to crank up the van; its yer EYES what tells ya what to rig.
