The Lowdown
Alright folks, Rusty here. Let's have a look at what Omaezaki is serving up over the next couple of weeks.
The opening call is a bit of a teaser. Monday the 10th of August has the best surf of the whole period, but it’s a short window. We get a solid 5ft SSW swell wrapping in with an 11-second period, and the wind is absolutely glassy. The water is sitting at 80°, which is about 2° cooler than average for this time of year, so nothing too unusual, just a touch fresh. The combined wave energy is pumping at (1248), so there’s plenty of push. That Monday morning is the standout for experienced surfers – it’s clean, powerful, and the conditions are mint. Don’t expect it to be empty, though; crowds are sometimes an issue here.
After that morning, it’s a pretty quick drop-off. Monday afternoon gets messy with a cross-onshore breeze, and from Tuesday the 11th through to Thursday the 14th, we’re looking at a mix of cross-shore chop, onshore wind, and only small, weak swell. There’s a little spike on Wednesday the 12th morning with a fresh offshore wind and a clean 3ft wave, but the swell energy is weak at (413) and the size is pretty small. Thursday the 13th looks better with a glassy morning and a clean 3ft SSW swell, but again, it’s not going to set the world on fire. The energy is low at (301-324).
Friday the 14th through Sunday the 16th is more of the same: small, inconsistent waves in the 3ft to 4ft range, with the odd clean morning but mostly average conditions. The combined energy stays low to moderate, peaking around (414) on Saturday morning. The wind is mostly light and offshore or glassy on the mornings, but the swell just doesn’t have much grunt.
Then we hit a real lull. From Monday the 17th of August right through to Sunday the 23rd, it’s a long, flat run. The swell drops to 2ft to 3ft, with energy numbers falling into the double and low triple digits. There’s a few clean mornings, like Tuesday the 18th and Friday the 21st with glassy conditions, but the waves are tiny. Not worth paddling out for.
The last couple of days, Monday the 24th and Tuesday the 25th, see a bit of a lift in swell period – we get a 13-second groundswell on the 24th morning, but it’s coming from the wrong direction (E) with a weak 2ft and a cross-onshore wind. Tuesday the 25th afternoon has a 4ft SE swell with a 12-second period and a combined energy of (502), but it’s blown out by a 30 km/h onshore wind. That’s kite-surfing weather, not paddle surfing.
Overall, the one true standout is Monday the 10th of August, first light. After that, it’s a whole lot of waiting. Keep an eye on the forecast, because a run this blank tends to break eventually.
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.
