September: Maximum Period, Maximum Power
September pushes the average period to 12.9s - the highest of the year - while the average height stays solid at 5.6ft (1.7m). Ideal wind drops slightly to 24 percent, but the quality of the swell more than compensates. SW energy refocuses to 45 percent, WSW to 21 percent, SSW to 7 percent and W to 7 percent; that gives a cleaner, more southerly alignment for Express Point than the peak winter months. Lots of waves arrive at 5-6.5ft (1.5-2m) and 6.5-8ft (2-2.5m), with occasional XL bombs for the brave. The wind regime is still mostly offshore - NNW at 16 percent, NW at 9 percent, WNW at 10.5 percent - but W and WSW winds are more common than in June and July, so pick your days. Water temperature remains cold at 13.1°C. In short: the longest, most powerful lines of the season start showing up just as spring kicks in.
