The Lowdown
Alright folks, this is Rusty. Let's have a look at what's on the menu for Omaezaki over the next couple of weeks.
First thing you notice is there's a real struggle bus to start. The opening days of the outlook are pretty flat and messy. Monday the 17th through Tuesday the 18th, we're looking at tiny waves around the 2 ft to 3 ft, coming from the east with a short period, and the wind is a cross-offshore breeze. The combined energy is weak to moderate, and the water temp is sitting at 80°, which is about average for this time of year. Honestly, it's a tough run for a paddle. The swell is just too small and weak to get excited about. There's a glassy moment on the morning of Friday the 21st, but the swell is still tiny and from the SSW, so not really worth the drive.
We then hit a bit of a dead zone from Saturday the 22nd through to Monday the 25th. The wind swings onshore, gusting from the southwest, and the conditions are just poor. The swell tries to pick up, but it's blown out and messy. Not a good look.
Now, hang on, because things get interesting. There's a big pulse of long-period groundswell heading our way. Tuesday the 25th afternoon sees the first real energy pushing in from the SSE, with a 15-second period. The combined energy jumps, but the wind is onshore, so it's a write-off. Wednesday the 26th gets bigger, with 7 ft to 8 ft SSE swell, but again, the wind is onshore or cross-onshore, so it's not clean.
The standout window is the morning of Thursday the 27th of August. The stars align. We've got a solid 8 ft swell from the SSE, but the key is the wind swings to a light easterly, giving us a clean cross-offshore breeze. The combined energy is strong, and the period is a very long 15 seconds. This is the one to circle on the calendar. Omaezaki is a beach and reef setup, and with this long-period groundswell and a clean wind, it's going to be firing. This is going to be a proper session for experienced surfers only, as the size is over 8 ft. The water is still warm, and the crowds are likely to be around, so get there early.
The end of the run gets a bit wild. Friday the 28th through to the 1st of September, the swell is predicted to get massive, with heights over 10 ft and up to 15 ft. The combined energy is through the roof. The wind is clean, but the problem is the swell is simply too big for this break. It's a "watch from the shore" kind of situation unless you're on a very, very big board. The conditions are there, but the power is too much.
So, the bottom line: the first week is a washout. The second week has a massive, clean swell on the 27th of August that is the real deal for experienced surfers, but it gets too big after that.
Rusty, signing off.

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.
