Taito - surf spot statistics

Best Surf Season (October - March)

The winter half-year delivers the most consistent swell at Taito. As the Aleutian Low strengthens and cold fronts push across the North Pacific, we see a marked increase in long-period groundswell from the NE through E quadrants. The average wave period climbs above 9 seconds, often peaking in the 9.5s range during January and December, producing punchy to powerful waves. While the predominant winds blow from the N and NE – onshore for this ENE-facing beach – the percentage of optimal offshore flow from SSW through W remains low (16–20%). However, when a high-pressure system sets up over the Sea of Japan, light to moderate westerlies can align perfectly with the incoming NE swell, turning Taito into a clean, hollow peak. The average swell height hovers around 1.2–1.4 m, meaning waves are consistently in the fun-sized to solid range. The key is patience: waiting for those windows of offshore wind often yields the best surf of the year.

Fair Surf Season (April & September)

April and September represent transitional months where the swell source shifts. In April, the North Pacific storm track becomes less active; swell heights drop slightly to 1.3 m and period shortens to 8.6s. The dominant swell direction rotates to E and SE, with a notable increase in ESE swell (17.6%). This means more waves wrap around from the south, offering rideable but less powerful surf. Offshore wind odds improve to 24% in April, with frequent light to moderate SSW and SW winds creating clean conditions. September sees a return of better-defined E/ENE swell (13.8% ENE, 25.2% E) as early autumn storms begin to form, and the average period recovers to 9.1s. However, onshore NE winds still dominate (19.3% of the time), limiting clean surf to around 22% of the month. Both months offer decent chances for fun, rippable waves when the wind cooperates, making them a bridge between the low and high seasons.

Low Surf Season (May - August)

From May through August, Taito experiences its weakest surf conditions. The summer monsoon and stable subtropical high-pressure systems prevail, pushing the dominant swell direction to the SE and SSE quadrants. This orientation is far from optimal for the ENE-facing beach, resulting in small, weak waves that often wrap in with little power. Average swell height drops to 1.1–1.2 m, and period dips to 8.0–8.4s – borderline average to choppy. Although offshore wind odds peak during this period (29–37% from SSW/SW), the lack of groundswell from the N through E directions means the waves are often too small or messy. Summer days can deliver fun-sized, groveling conditions on a rare good swell, but generally, this is the time to explore other spots or enjoy the warm water with a longboard. The best bet is to watch for typhoon swells that can swing around from the east, though they are infrequent and often accompanied by strong onshore winds.

November: Winter's Preview

November continues the winter pattern with average swell of 1.2 m and a 9.1s period. The swell direction is more balanced: ENE (19.1%), E (20.7%), and ESE (16.8%) still dominate, but there is a notable increase in NE (8.5%) and even N/ NNE contributions. The period remains solid, providing punchy waves in the fun-to-pumping range. Wind patterns are similar to October: NE and NNE winds are frequent (32.1%), but offshore SW and WSW winds increase to 15.3% of the time. The arrival of stronger winter storms can push wave heights into the pumping category (1.5–2.5 m) from the NE, and when the wind shifts west, the conditions can be epic. The ideal wind percentage rises slightly to 19%, offering a few more clean days than October. November is a solid month for experienced surfers who can read the charts to catch those short but high-quality windows.
