Tsurigasaki Surfing Beach (Tokyo 2020) Surf Forecast and Surf Report

Right then, let’s have a look at what’s on the cards for Tsurigasaki Surfing Beach (Tokyo 2020). Honestly, the next week and a half is a bit of a write-off for decent paddling waves. There’s a lot of small, wind-affected slop, or complete flat spells, and I wouldn’t bother getting wet really until we get into the second week of August.

The trouble is the local wind. For the last few days of July and into the first few days of August, it's mostly cross-on or onshore, with a mix of easterly and northeasterly breezes making a mess of any small swell that does show up. The water temp is sitting at 79°F, which is about average for this time of year (anomaly of just 0.4°), so at least you won't be cold while you're sitting there waiting for a wave.

There’s a real gap through the end of July and the first day of August. The best you can hope for is Sunday afternoon the 26th – a tiny 3ft easterly swell with a short 7-second period giving weak energy (192). The wind is a light cross-off from the south, so the surface would be clean, but it’s inconsistent and likely barely breaking. You’d be scratching for scraps. Saturday the 1st of August offers a similar story with a tiny 2ft SSE swell.

The real story here is the massive swell that builds from the 3rd of August onwards. It’s a long-period groundswell, with periods hitting 15-17 seconds, but the real issue is the size. By the 5th of August, you’re looking at 10ft onshore Wednesday morning, blowing up to 12ft by the afternoon with a moderate onshore breeze. This is way too big for a beach break like this, and the wind is poor, so for a surfer it’s a write-off. The combined energy is massive (over 5500 and climbing), but it’s all for nothing with the conditions.

By the 8th of August, we’re seeing a 28ft swell from the SE with a period of 16 seconds and a light offshore wind. That sounds wild, but that’s triple-overhead plus and excessively dangerous for a beach break, even for experts. It’s a monster and not recommended for anyone on a paddle board. The kite surfers might be frothing at the setup though, because the wind looks clean and off-shore on the 8th morning.

The only decent window I can see for a proper surf is the 10th of August. The swell drops right back to a manageable 5ft from the ESE, with a nice 12-13 second period. It’s still not huge, but with a clean cross-off wind from the SSW, the conditions will be glassy and fun. The combined energy is moderate (618-648). It’s not the biggest, but it’ll be the cleanest and most user-friendly wave of the whole 16-day run. For that day, a morning session looks like the standout.

Alright, keep your eyes on that 10th for a chance at some clean lines. The rest of it is a write-off for us paddle surfers. Rusty.
