Perranporth - surf spot statistics

Perranporth in the United Kingdom offers surf conditions that vary significantly throughout the year, with the best months generally falling within the autumn and winter seasons. The peak surf months are from October to February, when ground swell dominates, providing higher-quality, more consistent waves. During these months, ground swell frequencies range between 50% and 80%, with mean swell sizes reaching 1.5m to 2.0m, ideal for experienced surfers. However, wind conditions during this period are often unfavorable, with bad winds (onshore or cross-shore) occurring 85% to 90% of the time, which can create messy wave faces. November through January sees the largest swells, averaging around 1.7m to 2.0m, but surfers must contend with strong onshore winds that frequently degrade surface conditions. Spring and summer, particularly from April to August, see a shift to wind swells dominating, reaching up to 77% in July, but with smaller wave heights averaging just 1.0m to 1.2m. While wind conditions are slightly less harsh than in winter, with bad winds still occurring 83% to 88% of the time, the overall surf quality drops due to the lack of powerful ground swell. September and March serve as transitional months, offering a mix of ground and wind swells, though swell size remains modest, around 1.2m to 1.6m. For surfers seeking the best balance between swell size and consistency, October stands out—it combines a solid 50% ground swell frequency, moderate 1.5m waves, and slightly better wind conditions compared to deeper winter months. However, those willing to brave harsh winds for bigger waves will find December and January the most rewarding, despite the frequent onshore blow. Overall, Perranporth is most reliable for surf in late autumn and winter, but surfers must be prepared for challenging wind conditions year-round.

November at Perranporth offers a mix of surfable conditions, though with some variability. The average swell height is 1.7m with a decent period of 11.0s, suggesting well-formed, rideable waves when conditions align. The most dominant swell directions are W, WNW, and WSW, providing consistent energy for the break. However, the majority of waves fall in the 0.5-2.5m range, with larger sets (over 2.5m) being relatively rare. Wind conditions are less favorable, with only 10% of days offering ideal offshore winds. The predominant winds come from the SW, WSW, and W, often bringing onshore or cross-shore breezes that can create choppy or less clean surf, especially at higher speeds (20-50kph). Surfers should watch for windows when winds shift lighter and more northerly for cleaner faces. While the swell is fairly consistent, wind quality limits the number of truly high-quality days—best suited for those comfortable with less-than-perfect conditions or willing to wait for the right tides and wind shifts.
