The wind is just fine in March, no worries there. I've been there during the Jan-March period and the wind was consistent with everything I read (15-20+knots everyday). There's no waves during the summer, only wind. Winter offers both. Chris, I'll be there for the month of March, no worries there either!
"January – March: on average about 80% of the days great wind. Sometimes light (14 – 19 knots), sometimes strong (20 – 25 knots). Great waves!! (also spots with flat water for those who don’t like waves) (also waves every day during the rest of the year, but the most days with higher ones from Dec - March)"
