Tywyn - surf spot statistics

Tywyn, located on the west coast of the UK, is a surf spot heavily influenced by Atlantic swells and prevailing winds. The best conditions for surfing are typically found in the autumn and winter months, when ground swells are more consistent and swell sizes are larger. The prime months are from October through February, with November to February offering the highest likelihood of good swell and manageable wind conditions. During this period, ground swell percentages peak (28-34%), mean swell sizes range from 1.3m to 1.5m, and wind conditions, though often challenging (bad winds 82-91%), still see occasional favorable days (9-18%). Winter months bring powerful swells, but strong onshore winds frequently create messy conditions. Spring and summer (April-September) see a significant drop in ground swells (2-23%) and smaller waves (0.6-0.8m), with wind conditions worsening (bad winds 80-97%). The worst time to surf is mid-summer (June-August), when swell energy is minimal, and onshore winds dominate. October and March can offer a balance, with decent swell (17-34%) and slightly improved wind odds (14-18% good winds). Surfers should target the colder months for bigger, cleaner waves, but be prepared for frequent wind-related challenges.

October at this spot offers moderate surf conditions with an average swell height of 1.1m and a decent period of 8.3s, suggesting relatively clean and organized waves when the swell is up. The best swell direction comes from the SW and WSW, contributing the highest percentage of waves in the 0.5m–2.5m range, with some bigger sets reaching overhead. However, the frequency of larger waves (over 2.5m) is low, making it more suitable for intermediate surfers rather than big-wave riders. Wind conditions are only favorable 14% of the time, with lighter winds (0–20kph) being more common from the south and southwest directions. Stronger winds (20–40kph) from the south and southwest can occasionally disrupt conditions, but the spot's exposure allows for some surfable days if winds stay moderate. Overall, October delivers workable waves with the potential for good sessions when wind and swell align, though consistency is moderate and conditions can be variable.
