Conditions at North Point in September
September: Winter's Last Roar Meets the First Spring Light
September is a transition month with plenty of leftover sting. Average swell height is still a solid 8.5ft (2.6m), and wave periods are long at 13.2 seconds. The SW and WSW directions continue to deliver the bulk of the groundswell at 28.4% and 15.9% respectively, with W adding another 3.5%. There is still real power in the water, and enough west in the swell direction to hit North Point well.
Wind-wise, ideal conditions remain stuck at 17%, and westerly onshore winds are still prominent. Yet the spring shift is underway: E/SE direction frequency begins to grow again as high pressure systems nudge north, and precipitation eases to 2.52 mm/day. Air temperatures average just 14.4°C but are climbing, and water is still 17.3°C. September rewards patience, especially late in the month when cleaner autumn-like windows appear.
