The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for the local stretch.

So, we're looking at a bit of a mixed bag for the next couple of weeks. The first solid week is a bit of a write-off thanks to messy winds and funky conditions, but there's a glimmer of something cleaner towards the end of the second week. The main event here is Tsurigasaki Surfing Beach (Tokyo 2020). Water temp is sitting at 81°, which is about average for this time of year, so no need for a thick wetsuit.

The first few days are a real struggle. From Wednesday the 12th through to the weekend, we've got onshore and cross-onshore winds making a mess of things. Swell heights range from 4 ft to 8 ft, but with the wind state, it's just choppy and poor. The energy on Sunday the 16th afternoon is a massive 2696, but with a 16 mph onshore wind, that's a washing machine, not a surf session. That's expert-only territory, and even then, it's not pretty.

We get a small window of something more manageable from Tuesday the 18th. The swell drops right down to 3 ft from the ENE with a period of 8 seconds, but the wind swings light and clean. The combined energy is a weak 191, so it's small and weak, but at least it's surfable. Wednesday the 19th is similar with a 3 ft SSE swell and clean conditions. It's all very ordinary, but you can get a few if you're desperate.

Now, Thursday the 20th is a real standout. The swell is tiny, only 2 ft from the SSE, but the wind goes glassy. That's a major positive. The water will be like a mirror. The energy is a very weak 119, so you'll be on a longboard just enjoying the glide. For a true surfer, that glassy morning is the best of the whole first week. Friday the 21st morning also has a nice offshore wind (WSW 9 mph) with a 3 ft swell, but that's a short period of 7 seconds.

The second week starts with a bit of a nothing-burger. A big wind event on Saturday the 22nd brings 6 ft of messy NE swell, but it's cross-shore and lumpy. Not worth it. Then it goes flat and small again until the end of the month.

The real highlight of the entire forecast comes on Thursday the 27th of August. We get a morning of glassy conditions again, with a 6 ft swell from the ENE. That's a solid size, and the glassy wind will make it super clean. The energy is a moderate 391. The period is a short 7 seconds, so it'll be a bit lumpy and not the most powerful, but for clean, shoulder-high waves with no wind, you can't complain. The afternoon gets a bit cross-shore, but that morning is the best bet for the whole 16 days.

So, to sum it up: the first week is mostly a bust. The best surf is the glassy morning of Thursday the 20th August for a longboard, and the absolute standout is the glassy morning of Thursday the 27th August for some proper waves.
Rusty.
