The Lowdown
Alright, this is Rusty checking in with the outlook for the Omaezaki area. The water temp is sitting at 81°, which is pretty much bang on normal for this time of year, so no surprises there.
The next 16 days are a real mixed bag with plenty of onshore junk to sift through. We've got a big gap of ordinary conditions right out of the gate before anything decent really shows up.
The first few days are a write-off, honestly. Saturday the 15th through to the end of the following week is mostly cross-off breezes with small, weak swell. The wave energy is low, sitting between 42 and 377 (weak to moderate), and the swell heights are struggling to hit 5 ft. It's clean enough for a paddle, but you'll be scratching for anything with a pulse. The Tuesday morning of the 18th has a brief moment of offshore wind from the ENE with a 2 ft swell, but it's tiny and the energy is only 124, so the outlook is very ordinary.
The first real standout comes on Tuesday, August 25th. This is a solid window. The swell picks up to 7 ft in the morning and 6 ft in the afternoon, coming from the ESE with a nice 13-second period (groundswell). The combined energy jumps to 1399 and 1171 (strong to very strong). The wind is a light cross-off breeze from the ENE and E, keeping things clean. This is proper surf for experienced surfers—it's a bit heavy for beginners. The optimum swell direction is from the south, so this ESE swell is a touch off, but the size and clean conditions make it the best on offer by a long way.
Wednesday the 26th and Thursday the 27th are still rideable with 5 ft and 3 ft from the ESE and E, but the wind is a bit stronger and the scores drop off. The energy is moderate (816 and 354).
Then look ahead to Sunday, August 30th. The morning session is a very promising sleeper. We've got a 4 ft ESE swell with a very long 18-second period. The combined energy is 980 (strong). The wind is a light offshore from the ENE. This is a big, clean groundswell that will wrap in nicely. Keep in mind that a long period like 18 seconds can make the waves a bit too lined up for a beach break, but Omaezaki is a mix of beach and reef, so the points and reefs should fire. The afternoon gets a bit cross-onshore, so hit it early.
Overall, the pick of the fortnight is clearly Tuesday, August 25th, with Sunday the 30th as a solid backup for the early morning session.

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.
