Llangennith - surf spot statistics

Llangennith in the UK offers varied surf conditions throughout the year, with the best months generally being autumn and winter when ground swells dominate and wave quality improves. From January to February, ground swells are most frequent (around 52-53%), with mean swell sizes around 1.3-1.4m. However, wind conditions are poor (87-89% unfavorable), often creating choppy surf. March sees a slight drop in ground swells (40%) and smaller waves (1.1m), maintaining challenging winds. Spring (April-June) brings weaker conditions, with ground swells dropping significantly (8-24%) and wind swells taking over. Swell size averages a modest 0.7-0.8m, and wind quality remains poor (87-91% unfavorable). Summer (July-August) is the least favorable, with minimal ground swells (3%), tiny waves (0.7m), and very poor winds (95% unfavorable). September marks a transition, with a slight uptick in ground swells (11%) but still subpar winds. October-December sees improving conditions, with ground swells increasing (23-46%), swell sizes growing (1.1-1.3m), though wind quality remains an issue (90% unfavorable). The prime window for surfers is late autumn to early winter (October-December), when ground swells return and wave heights increase, despite persistent wind challenges. January-February also provides solid swells but similarly tricky winds. For the cleanest and most powerful waves, advanced surfers should target the winter months, while summer offers only small, wind-affected conditions suitable for beginners or longboarders.

March at Llangennith offers surfable conditions but with some variability. The average swell height is 1.1m with a solid 10.0s period, providing decent energy for intermediate to advanced surfers. The most consistent swell direction is WSW (19.52% of waves in the 0.5-1m range, 12.31% in the 1-1.5m range), followed by SW, which also contributes larger waves (8.23% in the 1-1.5m range, 5.54% in the 1.5-2m range). However, the surf is often smaller, with nearly 60% of waves under 1m. Clean offshore winds are less frequent, with only 12% of conditions being ideal, while onshore winds (mostly SW, WSW, and W) can create choppier surf. Expect a mix of rideable days, but patience and timing are key—wait for WSW/SW swells with lighter winds for the best sessions.
