The Lowdown
Alright folks, it’s Rusty here, and I’ve been staring at the charts for Omaezaki. Look, I’m not gonna lie to you – the next few days are pretty grim. We’ve got onshore winds and weak, short-period wind swell all through Friday and Saturday, with only around 3ft of slop and a combined energy reading of just 107 to 153 (weak). The water is sitting at 27°, which is about average for this time of year.
But hang on to your leashes, because everything changes on Sunday the 2nd of August. We get a complete reset. The wind goes glassy, dead calm, and a long-period groundswell arrives from the southeast. The swell is 4ft with a period of 16 seconds, and the energy jumps to 628 (moderate). That’s the standout morning of the whole forecast. The sets will be clean as a whistle, with long gaps between them making it easy to get out the back. With the swell direction coming from the southeast and the optimum for Omaezaki being from the south, it’s a solid match. Just be aware, this is a beach and reef setup, so that long period might make it a bit straight at the beach, but the reef sections should handle it beautifully. Crowds are possible here, so get there early.
The afternoon on Sunday gets a bit tricky with a cross-shore breeze, but the swell stays solid.
Monday the 3rd of August is a special one for the experienced crew. The swell builds to 6ft in the morning and 7ft in the afternoon, still from the southeast, with a period of 16 to 17 seconds. The wind is light offshore from the northeast, so it’s clean and lined up. The energy is strong, hitting 1647 and 2771. This is big, powerful, and excellent. Not one for the beginners though, as it’s over 5ft.
Now, from Tuesday the 4th of August through to Saturday the 8th, we get a monster swell. We’re talking 10ft up to 18ft, with energy readings from 5567 all the way up to 16627 (very strong). The wind is offshore or cross-offshore, so the conditions are clean. But here’s the catch – the swell is just too big for this break. The data says it’s too big. This is expert-only territory, and even then, the size and power will be overwhelming. It’s more interesting for kite surfing than paddle surfing for most of us.
After that, the swell drops back. Sunday the 9th of August has a messy 7ft swell with crossing winds, so it’s marginal. Monday the 10th and Tuesday the 11th offer a drop in size back to 5ft to 6ft, with clean offshore winds on the mornings. The energy is still present (1163 to 1516), and the period is still a long 12 seconds. These are decent, workable days, but not the standouts.
The final days from the 12th to the 15th of August see the swell fading further, down to 3ft to 5ft. The wind is offshore, but the energy is dropping (326 to 843). The period stays around 11 to 13 seconds, so the shape will be okay, but the size is small. The mornings look best.
So, to sum it up: the absolute best on offer is the glassy Sunday morning of the 2nd of August. For the bigger, more powerful stuff, the morning of Monday the 3rd of August is the pick for experienced surfers. Everything else is either too small, too big, or too messy.
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.
