September: The North Wind Takes Over
September marks a quality regression at the Superbank. Average period drops to 7.8s and ideal wind hits just 38%, while the swell average remains 3ft (0.9m). Swell directions diversify: E 21%, ESE 17%, SE 15%, but NNE jumps to 13% and NE/ENE are also present, meaning more short-period easterly and northeasterly slop. The biggest feature is the wind field: NNW is dominant at 21%, with N and NNE adding another 11% - the worst quadrant for a north-facing bank. Southerly winds still appear but are less consistent. Water temp hovers near 20.5C, so this is a classic 'pick your morning glass-off' shoulder-season month.
