The Lowdown
G’day, Rusty here. Let’s cut through the noise and talk about what Omaezaki’s got on offer for the next couple of weeks. To be straight with you, the opening act is a big, powerful beast, but it’s a case of too much of a good thing. We’ve got a solid stretch of surf, but you’re going to need to pick your moments.
The first few days are all about size and energy. The swell arrives with a serious punch, and it’s not messing around. The energy readings are way up there in the four-digit range (4791 at its peak on Sunday morning), so think strong to very strong. This is not a time for the faint-hearted or the learning crew. Anything over 8.2ft is expert territory, and we’re seeing 9.8ft to 11.5ft on offer through the early sessions.
Thursday, August 6th kicks things off with a solid 9.8ft SSE swell pushing through at 13 seconds. It's clean, with a cross-off breeze, but that size is just too much for the break. The wave comment says it all—too big for this spot. Same story for the afternoon, when it bumps up to 11.5ft. The energy is building (4055), and while the wind is workable, this is a pass unless you’re a proper charger with a death wish.
Friday, August 7th is more of the same. Still 9.8ft and clean in the morning, with the swell rotating a bit more to the south. The energy drops slightly but remains strong (3203). The afternoon backs off a touch but remains 9.8ft. The message is consistent: this is expert-only territory, and even then, it might be just a bit unruly for the setup.
We get a small reprieve on Saturday, August 8th. The swell drops to 8.2ft in the morning, which is still big, but the morning is clean under a light ENE breeze. The energy has dropped to 2557, which is still moderate to strong. However, the forecast rating is poor, so the quality might not be there. The afternoon sees it pick back up to 9.8ft with a cross-shore wind, which chops things up, so that’s a no-go.
Sunday, August 9th is the peak of this run. The swell holds at 9.8ft from the SSW, but the period extends to 15-16 seconds. This is a proper groundswell, and the energy is huge—hitting 5452 on the Sunday afternoon. It's a lot of water moving around. The wind is okay, but it’s still just too big for Omaezaki to be truly fun. This is a “watch from the cliff” kind of day.
Now, here’s where things get interesting.
Monday, August 10th, morning is your standout. The swell is still a respectable 8.2ft from the SSW at 14 seconds, but the wind goes almost dead—just a slight air—and the wave comment is a clear “excellent surf conditions for experienced surfers.” The energy is still hefty at 3014. This is the window where the size is enough to be meaty, but the conditions will be clean, and there’s actually a score attached to it. This is your best bet in this entire stretch for a real session. The afternoon looks to go a bit cross-on and the quality drops off, so get on it early.
After that, the swell starts to fade. Tuesday, August 11th sees the wind swing onshore from the southwest, and the surf quality goes to poor. The energy is dropping (1664 in the arvo), and it’s just a messy day. Don’t bother.
Wednesday, August 12th, morning brings a new, cleaner window. The swell drops to 6.2ft from the SSW, and with a light ENE cross-off breeze, it’s another “excellent” call. It’s not as big as Monday, but it’s still fun and punchy for a good surfer. The energy is moderate (1117), and the conditions are clean. Another good option.
From the middle of the second week, things get smaller and more inconsistent. Thursday, August 13th and Friday, August 14th are small to average, with

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.
