The Lowdown
Alright, crew, Rusty here. Let's break down this forecast.
The opening stretch is pretty lackluster. We've got some small, weak, short-period swell, but there's just no power behind it. You'll see some waves, but they'll be soft and unappealing. It's a good time to check your gear and wait.
The first real chance comes on the morning of Friday, August 21st. It's a small 0.8m SSW swell, but the wind is dead glassy. That's a huge plus for Omaezaki, a spot that can get a bit rough. It's not big, but it might be the only clean wave you'll find for a few days. The energy, at 166, is still weak, though.
The 22nd and 23rd are not worth your time. The swell from the SSW builds a bit, but it's straight onshore, which will tear it apart. Ordinary conditions, for sure.
Then it starts to fire. The morning of Monday, August 24th, a new, long-period SE groundswell starts to fill in. By the afternoon, it's pushing 1.6m at 16 seconds, with the energy jumping to 1417. The cross-onshore wind is a bit of a downer, but the power is there. Now, the morning of Tuesday, August 25th is the one to circle. The swell has built to a solid 2.4m, and the wind swings offshore from the ENE. Energy is a strong 2969. This is a proper, powerful swell. This is for experienced surfers only. The SSE direction is ideal. This is a standout day.
The swell doesn't stop there. Wednesday the 26th brings 3.0m to 3.5m waves with energy readings up at 5981. That is a ton of water, but it's just way too big for Omaezaki. You'd be in survival mode, not surfing. A definite no-go.
The 27th and 28th are a total washout. The huge swell is still running, but the wind is howling, making it pure chaos. You couldn't even get out. This would be better for the kite surfers.
By Sunday the 30th, it's still too big at 3.0m. But then, the morning of Monday, August 31st, the swell backs down to a much more manageable 2.4m. The wind is glassy, and the energy is still strong at 2408. This is another excellent window for the experienced crew. Clean, powerful, and rideable.
For the first few days of September, there are a couple of promising mornings. September 1st has a 2.4m ESE swell with a clean offshore wind, and September 2nd looks similar with a 2.5m SSW swell and offshore wind. These are longer-range calls, so they're promising but not set in stone. The water is about average for this time of year at 27°.
If you're picking your battles, make it the morning of Tuesday, August 25th, and the morning of Monday, August 31st. Those are your best shots at real, clean, powerful surf. Everything else is either too small, blown out, or just too dangerous.
Rusty, out.

Information about the Omaezaki Surf forecast
The above surf forecast table for Omaezaki provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Omaezaki can be found by selecting the local surf guide option on the grey menu. Our Omaezaki surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Omaezaki) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Omaezaki may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
