Stockton - surf spot statistics

Best Surf Season (October - March)

The North Atlantic roars to life during these months, and Stockton begins to see a marked uptick in both average swell height and period as strong extratropical storms march across the basin. With the south-facing orientation, the optimal swell directions from the S, SSW, SSE, and even SE become more prevalent. At the same time, the dominant high pressure builds in, delivering a higher frequency of offshore winds from N, NNW, NW, and NNE. This combination produces the most consistent and rideable waves of the year, with average heights hovering around 0.7m and periods often reaching the punchy 6-9s range. While truly firing days are rare due to the generally small size, when a low pressure sets up perfectly, we can see long period S swells wrapping in under sunny skies and light offshore breezes, creating fun, rippable conditions.

Fair Surf Season (April - May & September)

As the winter pattern fades, April and May offer a transitional mix. The swell window remains open to southern hemi swells, but the average height drops to 0.5-0.6m and periods lag around 6.6-6.7s. Offshore wind frequency decreases, and onshore southerlies become more common, especially in May. September sees a modest revival as early autumn lows begin to spin up, bringing average heights back to 0.6m and the highest average period of the year at 8.0s. However, the wind becomes a bigger factor, with ideal offshore conditions only 9% of the time. During these shoulder months, you have to pick your windows carefully to find clean, waist-high surf.

Low Surf Season (June - August)

Summer is the doldrums at Stockton. The North Atlantic settles down, and the dominant swell is from the SE, SSE, and S, but almost exclusively under 0.5m. The average height drops to 0.4m with periods up to 7.3s, but the combination of small, weak swell and frequent onshore winds from the S, SSW, and SW makes for choppy, messy conditions. Offshore wind is a rare commodity, clocking in at only 2-4% of the time. The few rideable days come from a stray tropical storm or a brief northerly wind event, but generally it's a time for groveling on micro-swell or enjoying other water activities. The surf is simply too small and wind-affected to produce quality waves.

May: Small and Challenging

May is a tough month at Stockton. The average swell height drops further to 0.5m, with a period of 6.7s. The swell direction is overwhelmingly from the SE, SSE, and S (49.9% combined, but almost entirely under 0.5m). The wind pattern turns unfavorable, with ideal offshore wind only 5% of the time. Onshore winds from the S, SSW, and SW dominate at 27.2%, and the strongest winds come from the SSW and SW, which are directly onshore for this beach. The NW and WNW offshore winds are weaker and less frequent at 13.4%. Waves are mostly micro, and the few 0.5-1m waves that show from the south are often blown out. It's a month for groveling with a high-performance shortboard, or accepting that the ocean is best used for swimming. Wait for a storm track that swings far enough south to send some long-period energy, but keep expectations low.
