Not a bad idea. Where are the windsocks?

Bob, its not really fair to call ikite misinformation. Its the only place where you can see all sensors at 1 glance. By the way, web cams won't show the kind of conditions you're describing. Sea breezes rarely are strong enough to cause whitecaps. I agree that a better array of sensors on the beach would be better but until then, ikite shows me all the sensors on one page and im not even a member. Best sensor for sea breezez is Clearwater.

In fact a good sea breeze will almost always produce white caps, factors such as depth of water and current considered. White caps will start on the water in breezes that you can not even ride in, 7- 10 kts. But don't take my word for it, check out the oldest system for determining wind speeds with out any tools or meters (over 200 years in use).
http://en.wikipedia.org/wiki/Beaufort_scale At beaufort 3 white caps are seen on the water and we usually need beaufort 4 before we can enjoy our sport. Keep in mind the location of the Clearwater sensor is out on the pier. It is located about 3/4 of the way out, in between two roofed structures. One to the east of it and one to the west of it. These both have hip roofs on them. The proxcimity to these roofs can result in a disturbed flow to the sensor on east and west winds and a venturi effect on north and south winds. Hense the numbers you get on east and west are usually less than actual and the numbers you see on north and south winds are usually greater than acutal. Keeping this in mind the Clearwater sensor is very helpful in our area, right now it is our best sensor untill they get Howard Park up and running again. The Howard park sensor was the best indicator of a sea breeze that I have found. Clifford C. Clavin, Jr.

In terms of a good sea breeze rarely causing a whitecap... never heard that argument. Hard to discuss a web cam's value if you actually believe that assumption. Glad you like iKite.

Its true, I kite does blow, big ones! Can't tell you how many times I have been burned by imight...
I pay attention to wind direction on the sensors and usually the trendline on the forecast. unless its holding steady at 20+ and its obviously blowing outside I give them 0 weight. Wind is wind too so if there are white caps it doesn't matter if its a seabreeze or not, it should be enough to ride  Quote:

You didn't offend me, HR. I did a quick check though, to make sure I wasn't coming from left field in my assumptions about white caps.
"Full on whitecaps" does not appear to be a classification in the Beaufort scale. Numerous whitecaps is a classification though, and 14 knots is easily enough to produce them. Scattered whitecaps appear to start fairly shy of 17 knots (like 10 or so). It's just a chart with numbers on it, though. Prolly best to watch the birds, not the water surface (via cam or live) for sure. http://www.spc.noaa.gov/faq/tornado/beaufort.html And yes, I can be sarcastic.
