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.
