The Lowdown
Alright, Rusty here. Let's take a look at what's cookin' for Omaezaki.
Honestly, for the next week or so, it's pretty grim. We've got swell on the way, but the wind is gonna mess it up. You're looking at a whole lot of onshore and cross-onshore breeze smashing the waves flat and ugly from now through to at least the 28th of August. After that, it's just weak and small with not enough energy to get excited about. You'll be sitting there watching bumpy lines, not really worth paddling out for.
But, hold onto your board, because we have a window that looks far better. The standout action is slated for Monday the 7th of September through Tuesday the 8th. Omaezaki (Shizuoka) will finally get good. The water temp is bang on average for this time of year at 81°, so you won't need the thickest wetsuit. On Monday the 7th, expect clean conditions with a gentle offshore breeze from the NE in the morning, and a light breeze in the afternoon. We're looking at a solid 5ft to 6ft of swell from the SSE with a decent 12-second period. This generates moderate to strong wave energy (1095 to 1218) and the offshore wind will have those lines standing up beautifully. This is better for more experienced surfers as it's pushing over 5ft.
Then Tuesday the 8th cranks it up a notch. The morning sees a moderate offshore wind from the NE with swell building to 7ft from the SSE, and by the afternoon it's hitting 8ft from the SE. This is strong energy (1203 to 1562) and will create some excellent, powerful walls for those who know what they're doing. Remember, when the swell is over 8ft, it's getting into expert-only territory, but this is a fine size for a confident surfer on a point or reef setup. The combination of clean offshore/cross-off wind and a solid south groundswell makes this the best on offer.
Later in the window, Wednesday the 9th of September has a touch more size (up to 8ft from the S) and very long 13-second period, but early signs show the conditions might be a little more marginal. It'll still be clean, but the swell direction could make it a bit tricky at this beach and reef setup.
All in all, you've got to be patient. Suffer through the first week of wind, and you'll be rewarded with a classic late-summer pulse on the 7th and 8th. Keep an eye on it.
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.
