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.

Caswell Beach in February typically offers surfable conditions, though with some variability. The average swell height is 1.1m with a decent period of 10.5s, suggesting moderately clean and rideable waves, particularly when the swell direction aligns favorably. The predominant swell directions come from WSW (23.5% of waves in the 0.5-1m range and 16.3% in the 1-1.5m range), which often produces the best waves for this spot. SW swells also contribute, but with slightly more power (3.5% in the 1-1.5m range and 2.8% in the 1.5-2m range). Smaller swells from other directions are less consistent or impactful. Wind quality is a limiting factor—only 11% of the time are conditions ideal (likely light offshore or cross-offshore winds). The most common wind directions are from the SW and WSW, which can be onshore, creating choppy conditions. However, when winds shift W or WNW, the surf can clean up. Expect a mix of smaller, weaker days and occasional punchier sessions, but overall, persistence and timing are key to scoring good waves here in February.
