Mayport Poles - surf spot statistics

Best Surf Season (October - March)

The North Atlantic winter pattern drives a slight uptick in wave energy at Mayport Poles during these months, with average swell heights hovering around 0.6-0.7m and periods stretching into the 7-second range. This is when the Atlantic low-pressure tracks become more active, spinning up cold fronts that push swell from the ENE through ESE—directions that align well with the east-facing beach. While the heights are modest, the combination of slightly longer period and a higher chance of offshore winds from the west (WNW, NW, W) during post-frontal setups can produce clean, rideable conditions. November and December offer the highest percentage of ideal wind (17%), making those months the prime window for scoring fun-sized waves when the stars align.

Fair Surf Season (April - May, September)

Spring and early fall serve as transitional periods. April sees the tail end of winter swell but with a drop in period (6.5s) and ideal wind (12%). Swell becomes increasingly dominated by E and ESE, which is okay for direction but often accompanied by onshore winds from the same quadrants as the Bermuda High builds. September stands out with the highest average period (7.5s) and a bump in swell height (0.7m), thanks to early-season tropical systems and the onset of Atlantic storm activity. However, ideal wind sits at only 10%, and the prevailing easterly flow makes clean conditions a gamble. Still, when a tropical system or cold front aligns, the quality can be surprisingly good.

Low Surf Season (June - August)

Summer is the most challenging time at Mayport Poles. Average swell heights drop to 0.5m, periods hover around 6.1-6.8s, and the percentage of ideal wind plummets to just 6-7%. The dominant swell direction shifts strongly to ESE and SE, which, while technically in the optimal swell window, rarely produce enough energy to overcome the persistent onshore trade winds. The Bermuda High locks in a steady E to SE flow, meaning the wind is almost always blowing directly into the beach. Wave quality is often choppy and messy, making it a time for small-wave gear and low expectations. The rare exception is a tropical system that tracks favorably, sending pulses of longer-period swell ahead of its approach.

July: Peak Summer Slump

July is the lowest point of the year for surf quality. Average swell height is 0.5m, with a period of 6.6s. The swell is overwhelmingly from the ESE (41.4%) and SE (32.9%), with nearly all waves under 0.5m. Only a tiny fraction reaches 1m. Ideal wind remains at a dismal 7%. The wind pattern is dominated by SW (15.0%), SSW (13.0%), and WSW (12.0%)—all onshore for this east-facing beach. The persistent flow from the south and southwest, often associated with the western edge of the Bermuda High, creates constant messy conditions. There is virtually no chance of decent surf unless a tropical storm or hurricane tracks close enough to generate strong, longer-period swell from the east or southeast. Even then, the wind is likely to be onshore. July is a month for flat spells and low expectations.
