This is the most inaccurate weather site
I checked against other sources which are in agreement and the differences between those and this site are way too large , wind off by 20 kts and temp by 11 C .
It isn't. Windy is forecast..not actually weather. And forecast is forecast..
I just checked every stat and screen I could for San Diego, the area I live in, and all of them were correct, spot on. So respectively, I disagree with you. If there is some place with bad data, you should document it, take some screen shots and post them here for the programmers to check out.
