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.

July at Llangennith offers generally small but rideable conditions for surfers, with an average swell height of 0.7m and a decent period of 7.7s, providing some energy despite the modest size. The dominant swell direction is from the WSW (27.5% of waves under 0.5m, 34.1% between 0.5-1m), which aligns reasonably well with the beach’s orientation, though larger swells (1m+) from this direction are less frequent. SW swells also contribute, particularly in the 0.5-2m range, adding occasional punchier sets. Wind conditions are less favorable, with only 5% of days offering ideal offshore or light cross-shore winds. The prevailing wind direction is WSW to W, often blowing in the 10-30kph range (onshore or sideshore), which can create chop and reduce wave quality. Stronger winds (>20kph) occur around 15-20% of the time, further limiting clean surf opportunities. For advanced surfers, patience and timing are key—early mornings or rare wind shifts may provide brief windows of cleaner waves, but expect mostly small, slightly messy conditions with occasional fun peaks when swell and wind align.
