Conditions at Llangennith in June
June: Summer Doldrums and the Dawn Patrol Window
June brings the true doldrums. Average swell height stays at 2.5ft (0.8m), but the period shortens to 7.9s, which puts it in the marginal, choppy category a lot of the time. WSW still dominates at 46.2% and W at 25.4%, but virtually all of that swell is below 3ft (1m), and waves over 5ft (1.5m) are rare. The ideal offshore wind percentage drops to only 6%, and the NE-ENE-E-ESE wind share falls to 15.9%. Sea breezes and weak westerly gradients dominate the afternoons, often adding cross or onshore chop to already small surf. Water temperature climbs to 15.0°C and air averages 14.2°C, making it a pleasant beach day but not a serious surf destination. Early mornings are the only real chance to score clean waist-high peelers, and you will be relying on lingering W/SW swells rather than new Atlantic energy.
