Global wind map points the way to good surf conditions

I saw this image on a Clean Tech blog about the potential of offshore wind farms. As we all know, more wind = more swell and less coastal wind = more glassy conditions.

A few points to make:

1) Check out the southern Indian Ocean vs. the southern Pacific Ocean in the bottom "Northern Summer" image. Higher wind intensity in the southern Indian Ocean = relatively more swell for Indo and West Oz.

2) Check out how dead the North Pacific is in Northern Summer and how the Southern Hemisphere is still pretty lively during Northern Winter. This is why the North Shore is dead flat in summer but exposed places in Chile, Peru, Oz, South Africa, and Indo have surf year round.

3) Check out how calm the wind is off Angola in Northern Summer. It's one of the biggest purple spots on the map and would be receiving significant southern hemi swell at that time of year.

4) Check out the crazy intense wind off the horn of Africa in Northern Summer - Wow, what the hell?
