It averages 5.3 m/s year around here. That's about 10.3 knots or 11.8 mph, just at the threshold for a useful wind generator, but they are too tall for local height ordinances.

Apparently the rules are looser in Kennebunkport.

That map is notoriously inacurate, and ignores local geographic anomolies.
It's for very broad generalisations only.
