The Lowdown

Alright, mates, Rusty here. Let’s break down this next stretch.

We kick things off with a bit of a thump, but it’s not for the faint-hearted. The water’s at 80°, which is a touch cooler than normal for this time of year, so you might feel it.

Saturday morning, August 8th, is the first real call. Omaezaki is seeing a clean 7ft of south swell, with a period of 11 seconds. There’s some serious power behind it, and the light east cross-off breeze is going to keep the surfaces clean. The combined energy is a solid 1169, so there’s plenty of push. This is one for the experienced crew – that size is too much for beginners. The swell direction from the south is spot-on for this break. It’s fairly consistent, so you’ll get waves, but it’s not a session to be taken lightly.

The rest of the weekend and into the start of next week is a bit of a letdown. Sunday and Monday mornings still have some clean, rideable surf in the 5ft to 6ft range, but the winds are more variable, and afternoons get chopped. Monday morning, August 10th, is worth a look though – it’s glassy with a 6ft south-southwest swell and a 12-second period. That’s a nice, clean window before the wind gets on it. The energy is still strong at 1315, but Saturday’s call is the better one.

Then it turns poor. From Tuesday afternoon through the whole of the following week, the swell drops and the wind gets messy. There are a couple of mornings with offshore winds, like Friday and Saturday, the 14th and 15th, but the swell is down to 3ft or less. It’s clean, but it’s small and weak – okay for a longboard if you’re keen, but nothing to get excited about. The energy readings are in the low hundreds, which tells you it’s gutless. This stretch is a write-off for real waves.

There’s a gap there where it’s just flat and boring, and you might be thinking of storing the board. But hold on.

Thursday morning, August 20th, the ocean wakes up again. We’ve got a fresh pulse of 7ft south swell, with a period of 9 seconds. The period is a bit short, so it won’t have the same grunt as a long-period groundswell, but the energy reading is 775, which is moderate. The wind is light and offshore, so it should be clean and lined up. This is looking like the other standout of the window. Again, it’s a good size, so not for the learners, but for the experienced, this is the one to mark on the calendar.

After that, it fades out. The winds turn onshore and the energy drops away into the weekend. There’s a faint glimmer on Sunday morning, the 23rd, with an easterly swell and a long 12-second period, but it’s only 2ft. Long period and clean, but too small to get the heart racing.

So, the two standouts are Saturday morning, August 8th and Thursday morning, August 20th. Both have similar size, from the south, and with clean winds. The first one has a bit more period and energy, making it the pick of the bunch. The second is a little less certain being further out, but it looks promising. Everything else in between is pretty average, so pick your moments.

Remember, when it’s over 5ft, it’s not for the beginners, and when it’s over 8ft, it’s only for the experts. Stay safe out there.

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.
