Conditions at Rhossili Bay in October
October: The Atlantic Roars Back to Life
The North Atlantic drama resumes in October, and Rhossili's average swell height jumps back up to 1.2m (3.9ft). The average period sits at 8.6s, but the first strong low-pressure systems are already capable of laying down powerful W/SW groundswell. The wave rose shows a solid increase in SW swell (12.3%) alongside WSW (35.3%), meaning more waves are pushing directly into the bay. The wind is the wildcard: SW and WSW winds remain prevalent, with onshore directions around 33% of the time, but E/SE winds also show a notable presence, which can keep the lineup glassy between fronts. Water temperature remains pleasant at 14.6°C and air temperatures average 12.8°C, so you can still get away with a lighter wetsuit. October is when the magic starts: the storms return, the nights draw in, and Rhossili transitions from summer mush to serious surf.
