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.

February at Llangennith offers surfable conditions with an average swell height of 1.3m and a solid period of 10.6s, indicating consistent, well-organized waves. The majority of swell comes from the WSW (peaking in the 0.5-2.5m range), which aligns well with the beach orientation, producing clean, rideable waves. SW-WSW directions dominate, with 12-17% of swells in the 1-2.5m range—ideal for intermediate to advanced surfers. Wind conditions are less favorable, with only 13% of days offering ideal offshore/light winds (mostly from ENE-E). Strong onshore winds (SW-WSW) are common, reaching 20-40kph in ~20% of cases, which can create choppy conditions. Smaller days (0.5-1.5m) are frequent (~60% of the time), while overhead waves (2m+) occur ~15% of the month. Expect a mix of clean, mid-sized sessions when winds cooperate and rougher days when SW winds prevail. Winter wetsuits (5mm+) are essential. Overall, February delivers decent surf—best suited for those ready to chase the cleaner wind windows.
