The Lowdown

Alright, let’s talk about what’s coming up at Omaezaki. This beach-and-reef break is exposed from the south, and the best direction for the swell is out of the south, so we’ll be keeping an eye on that. Water temp is around 80°, which is just about average for this time of year—nothing wild.

The start of the period is rough. Tuesday the 11th is a complete loss with onshore wind and a messy 5ft east swell, period around 10 seconds. Wave energy is moderate (778), but it’s all chopped up. Wednesday the 12th has clean offshore wind from the ENE at 22 mph, but the swell is tiny at 3ft from the SSW, period 10 seconds. Energy drops to 265. It’s a longboard day at best. Thursday the 13th stays marginal with the same small 3ft SSW swell, clean but weak (energy 283).

Friday the 14th is the first real chance. Clean conditions with a light ENE offshore breeze, 3ft east swell, 10-second period, energy 357. It’s not pumping, but it’s surfable. Saturday the 15th is similar—3ft east swell, moderate offshore wind, clean—but still nothing to write home about.

Sunday the 16th is the first alert. Glassy morning with a light southerly breeze, 5ft east swell, period 10 seconds, combined energy of 702. That’s a solid, moderate energy wave with a clean face. The afternoon turns cross-onshore, so the morning is the go. Crowds can be a thing here sometimes, so get in early.

Monday the 17th morning stays glassy with a clean 3ft east swell, energy 266. Smaller but still okay. The afternoon drops to 2ft and goes poor.

Then we hit a dry run. Tuesday the 18th through Thursday the 20th are all poor or marginal, with onshore wind building and messy south and south-west swell. Energy stays moderate, but quality stinks.

Friday the 21st has a glassy morning again, 5ft SSW swell at 10 seconds, energy 420. Clean, but the afternoon goes to junk. Saturday the 22nd morning is glassy, but only 3ft.

Now, the real standout is Tuesday the 25th of August. The morning is glassy, calm, with a 5ft swell from the SSE at a long 13-second period. Combined energy is 921—strong. That’s a proper groundswell. Long-period stuff like this can run past beach breaks, but on a reef set-up like Omaezaki, it should line up nicely. That morning is your session. The afternoon gets messy with a cross-onshore, so be there early.

Wednesday the 26th the swell jumps to 7ft from the south, period 12 seconds, but it’s onshore and energy shoots to 1560. That’s expert territory. Afternoon hits 8ft (energy 2062) and is still onshore—a mess unless you’re very skilled.

Best bets: the morning of Sunday the 16th and definitely Tuesday morning the 25th of August. Don’t miss that Tuesday.

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.
