Tadado seasonal overview
Best Surf Season (September - October)
The transition months of September and October are where Tadado truly comes alive. As the North Pacific high retreats and the first strong cold fronts dive south from Siberia, the Aleutian low begins to stir, but more importantly, the lingering tropical typhoon activity in the western Pacific still pumps long-period S and SSW swells toward the Japanese archipelago. At the same time, the seasonal wind shift to the N-NE offshore quadrant begins, grooming those south swells into clean, hollow lines. The combination of powerful 8-10s period swell from the south and offshore winds from the north creates the most consistent windows of quality surf all year. You can still score S/SSW groundswell in October, although the window slowly narrows.
Fair Surf Season (March - June & November)
Spring and early summer offer a decent run of rideable south swells, but the trade-off is a less reliable wind regime. Migrating frontal systems and developing thermal troughs bring a mix of offshore N-NE winds and onshore S-SW winds; when the two align, Tadado offers fun, rippable waves. November is another fair-weather month with plenty of offshore NE wind, but by then the tropical south swell engine is shutting down, leaving mostly short-period cross-shore energy. Consistency is moderate, and the size is generally in the fun-sized to solid range, but you'll need to pick your windows carefully.
Low Surf Season (December - February & July - August)
The dead of winter and the heart of summer are Tadado's slowest periods for different reasons. From December to February, the northwest monsoon blows hard from offshore, but the dominant swell direction is from W-NW, which is swallowed by the south-facing coastline; the beach remains small and virtually flat for days on end. In July and August, the opposite problem occurs: plenty of S/SSW swell is on offer, but the same southerly/southwesterly winds that push it also blow directly onshore, leaving the surface chopped and often stormy. Unless a typhoon tracks ideally and draws in offshore NE flow, these months are best left for longboards and low expectations.
