Caswell Beach - surf spot statistics

Caswell Beach in the UK offers surf conditions that vary significantly throughout the year, with the best surfing months typically being during autumn and winter. The data shows that from October to February, the swell quality and size are more favorable for surfers, with ground swell percentages peaking in December (43%) and January (49%). These months also have larger mean swell sizes, averaging 1.0–1.2 meters, which is more suitable for intermediate and advanced surfers. Wind conditions, however, are consistently poor throughout the year, with bad wind conditions dominating 89–93% of the time, making clean surf sessions rare. The worst months for surfing are from May to September, when ground swells drop sharply (2–10%), and swell sizes diminish to 0.6–0.7 meters, often resulting in weak, wind-affected waves. Wind swells become more dominant during this period, but they provide less consistent and lower-quality surf. Overall, the prime window for good waves at Caswell Beach is late autumn through early winter, particularly November to January, when ground swells are more frequent and wave heights are more substantial—despite the challenging wind conditions that require careful timing for the best sessions.

**Surf Conditions at Caswell Beach in April:** April at Caswell Beach offers a mix of surf opportunities, though conditions are generally modest. The average swell height is 0.7m with a decent period of 9.1s, providing some rideable waves, albeit smaller and less powerful. The swell direction is predominantly from the WSW (27.7% of waves in the 0-0.5m range, 26.4% in 0.5-1m), which often aligns well with the beach’s orientation to produce clean, workable waves, particularly when winds cooperate. However, larger swells (over 1.5m) are rare, only occurring around 11.3% of the time. Wind conditions are crucial here—only 11% of the time is the wind ideal (light offshore or cross-offshore). The most common wind directions are W and WSW, often blowing in the 10-30kph range (onshore or cross-shore), which can create choppy or less clean conditions. While there are occasional cleaner days with lighter winds from the NE or ENE, stronger onshore winds (20-30kph+) are frequent, limiting optimal sessions. For surfers, April is a mixed month—small but ridable waves when the wind aligns, but expect frequent onshore bumps. Best bets are early mornings when winds are lighter or during brief periods of offshore flow. Advanced surfers may find some punch in the occasional WSW swell over 1m, but overall, it’s best suited for logging or smaller-wave boards. Keep an eye on wind forecasts for those elusive clean sessions.
