Conditions at Mekakoz in September
September: The Atlantic Starts to Stretch
September is a game-changer at Mekakoz. The average swell height climbs back to 4ft (1.2m) and the period lengthens to 10.3s - a sign that the North Atlantic is waking up after a summer sleep. The direction is still heavily biased to the NW (51.8% of wave energy), with NNW (19.6%) and WNW (13%) filling out the picture. More importantly, the wind regime becomes markedly more favourable: ideal offshore flow from the S/SSW/SW/W sector occurs 36% of the time, the second-highest value of the year. As the Azores High begins to weaken and the first cold fronts push into the Bay of Biscay, we get the classic autumn recipe: fresh NW groundswell with post-frontal S/SW offshore winds. The ocean is still warm from a summer of sun - 20.4°C - and the air is a pleasant 19.5°C. This is the month when the transition from summer slop to serious surf really begins. Dust off your shortboard.
