The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, we’ve got a rough start. Friday the 21st and Saturday the 22nd are a write-off. The wind is howling onshore and the surf is weak and messy. You’re better off doing something else.
We finally get a bit of life on Sunday the 23rd morning. Omaezaki will have some surfable waves, but it’s nothing to write home about with a weak 3ft SSW swell and a short period. The wind is cross-off, so it’s clean, but very ordinary. The wave energy is still low at 174.
Now, hang on to your boards, because Monday the 24th is where it gets good. A proper groundswell arrives. The morning sees a 6ft SSE swell with a very long period of 17 seconds. The wave energy is pumping at 2103. The wind is light and cross-off, making for excellent, clean conditions. The water is sitting at 79°, which is a bit colder than normal for this time of year, so you might want a spring suit. This is for experienced surfers as the size starts to get up there. The afternoon gets bigger but the wind turns cross-on, so the morning is the window.
The standout, and I mean the *real* standout, is Tuesday the 25th. The morning is glassy. Zero wind. A solid 10ft SSE swell rolling in with a 14-second period. The energy is massive at 3615. This is a big, powerful, clean swell. However, and this is a big however, 10ft is too big for this break. This is strictly for experts only. The afternoon is also 10ft but with a cross-shore wind, so the morning is the pick if you’ve got the skills.
Wednesday the 26th is still solid for the experienced crew. 8ft S swell in the morning dropping to 7ft from the SSW in the afternoon. Both have clean conditions with cross-off winds. The energy is still strong at 2228 and 1388.
After that, things get messy again. From Thursday the 27th right through to Saturday the 29th, we’ve got onshore winds, rain, and deteriorating surf. The swell is there but the conditions are poor. It’s a bit of a blank run.
We get a nice reprieve on Sunday the 30th. The wind swings offshore from the ENE. The swell is smaller at 3ft from the SE, but with a light offshore breeze in the morning, the conditions will be clean and very good. The afternoon is also clean with a light offshore. This is a great option for all levels.
Monday the 31st is also a good, clean option. Offshore winds again with a small 3ft to 3ft swell. Good for a longboard.
The first week of September looks a bit uncertain. Tuesday the 1st and Wednesday the 2nd have fresh offshore winds which will keep things clean, but the swell is small, and the conditions are described as marginal. The wind is strong, making it tricky.
The next real promise comes on Thursday the 3rd of September. A 5ft ESE swell with a very long 17-second period. The energy is strong at 1540. The wind is a moderate offshore, so it will be clean. A bit big for beginners though.
Then, Friday the 4th of September is another big one. A 10ft ESE swell with a 14-second period. The energy is massive at 3693. The wind is gentle offshore, so it will be clean. But again, this is 10ft. Too big for the break, and only for experts.
Saturday the 5th of September drops back to a more manageable 6ft from the E, but the wind is a fresh offshore, so it will be clean, but powerful.
Overall, the best windows are Monday the 24th morning and Tuesday the 25th morning for the experts, and Sunday the 30th and Monday the 31st for everyone else. Long range, Thursday the 3rd of September looks promising but is less certain.
Rusty.

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.
Omaezaki is 1 km (1 miles) from Oyama. If you plan a holiday in Shizuoka, look for hotels and other accommodation in Oyama. Oyama has rooms for a wide range of budgets as well as car hire and transport links.
