June: Windswell Season Arrives
June at Rhossili is about learning to love the small stuff. Average swell height is 0.8m (2.6ft) and average period drops to 7.9s, as summer's short-period windswell takes control. The swell direction is still overwhelmingly WSW (46.2%) and W (25.4%), but the vast majority of that energy falls under 1m, making it marginal for the open beach. Wind patterns are the biggest challenge: W/SW winds are now firmly onshore and pick up through the day, with WSW and W winds combining for over 27% of the observations. Onshore sea breezes and weak Atlantic high pressure keep most days soft and lumpy. Ideal offshore flow has dropped to 7%. With water temperatures at 15.0°C and air temperatures around 14.2°C, summer rubber is on, but patience is just as important as board choice. Early mornings and the occasional weak North Atlantic front offer the best odds for groomed, waist-to-chest-high waves.
