Conditions at Brusand in September
September: First Atlantic Roar
September is one of the most underrated months at Brusand. The North Atlantic begins to re-awaken as the first strong extratropical cyclones of autumn deepen; average wave height jumps to 4.3ft (1.3m) and average period lengthens to 7.5s. The wave rose shows a healthier spread of energies: NW and WNW remain common at 16.5% and 14.7%, but the S-SSW/SW/WSW window grows to 32.4%, with SW and WSW each contributing 9.7%. This means Brusand's south-west exposure is more consistently in the firing line. The wind picture is still mixed - NNW winds dominate at 18.0%, with ESE and SE also strong - but the ideal N/NE offshore quadrant totals around 6.7%, yielding 16% clean conditions. Water temp is still a pleasant 15.1°C, air temp averages 12.8°C, and rainfall is moderate at 4.99mm/day. A September long-period SW groundswell with NE wind is a hidden gem: still warm, still strong, and not yet beaten up by winter.
