Conditions at Maceda in September
September: First Hints of Autumn
September is when the Atlantic starts showing signs of life again. Average swell height climbs back to 1.1m (3-4ft) and period lengthens to 10.4s, signaling the return of more organized groundswell. WNW and NW share the limelight at 42.0% and 39.3% respectively, so the favored westerly window is well represented. Ideal offshore wind frequency rises to 24%, and the thermal NNW tendency begins to break down a little. Air temperature averages 19.2°C, water is still warm at 17.1°C, and precipitation starts to increase slightly. Early-season Atlantic lows can throw some clean, punchy WNW swells that hold well, especially when the wind goes light easterly in the morning. Maceda starts to get interesting again - the board size slowly creeps up.
