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.

September: Tropical Potential

September is the most promising month for quality surf at Mayport Poles, driven by the peak of Atlantic hurricane season. Average swell height rises to 0.7m, and the period jumps to 7.5s—the highest of the year. Swell direction shifts, with ENE (24.4%), E (32.9%), and ESE (26.4%) leading the way. There is a notable increase in the 1-1.5m and 1.5-2m categories, especially from the ENE. Ideal wind improves to 10%, with offshore flow from the west occasionally occurring behind cold fronts. However, onshore winds from the NE (13.5%) and ENE (14.1%) are still common, often ruining the wave quality when tropical swell arrives. The key is to catch the brief windows when a tropical system approaches from the southeast, bringing powerful long period swell, and a cold front clears the coast, shifting winds to the west. Those sessions can produce excellent, firing waves.
