Conditions at Troia in November
November: Consistent Power and a Favorable Wind Shift
November delivers the full winter menu. Average swell height rises to 5.5ft (1.7m) and period reaches 11.9s, with plenty of 5-6.5ft (1.5-2m) and 6.5-8ft (2-2.5m) waves in the mix. Swell directions are spread across NW (30.4%), WNW (30.0%) and W (10.9%), with WSW/SW contributing another 6.0%; combined with W, the optimal window now makes up around 18% of all wave energy. The surf at Troia starts to look like an Atlantic point/bay hybrid: long walls, occasional peaky sections, and plenty of power.
The wind pattern is the real star. Ideal conditions sit at 43%, and the offshore NNE/NE/ENE/E quadrant totals around 28% - one of the strongest offshore wind months of the year. NNW is still present (17.4%) but no longer dominates. This combination of active low-pressure tracks and frequent easterly flows over Iberia means consistent, clean, surfable days. Air temps cool to 13.9°C, water is 16.8°C, and rainfall averages 2.82mm/day - those rains bring runoff, but they also bring the swell. November is a serious surf month.
