Conditions at Llangennith in April
April: Shoulder Season Grinds into Gear
April marks the shift toward smaller but more user-friendly surf. Average swell height drops to 3ft (0.9m) and average period falls to 9.0s, so Llangennith trades power for accessibility. WSW remains the dominant swell direction at 39.3%, with W at 21.6% and SW at 7.6%, but the bulk of the energy falls in the 2-3ft (0.5-1m) range. There are still days with 5-6ft (1.5-2m) swell, but they are less frequent. The positive spin is the wind: ideal offshore flow sits at 10% and the NE-ENE-E-ESE wind directions combine for 26.5%, the highest offshore share of the year. Spring highs are more common, making for cleaner conditions and more manageable surface texture. Water temperature is still fresh at 9.8°C and air averages 9.0°C, but spring sunshine and lighter winds make this a much more pleasant time to paddle out, especially on a longboard when the swell is small.
