The Lowdown
Alright, let’s get into it. The next couple of weeks are a real mixed bag for Omaezaki. We’ve got a slow start, but a solid run of groundswell and clean winds is shaping up if you can be patient. There’s a major pulse of energy rolling in, but it’s going to get a bit too wild for this spot by the time it peaks.
Right now, the surf is small and a bit ordinary. Sunday morning the 23rd has some knee-high waves at 3 ft from the SSW, period a short 8 seconds. The combined energy is weak (174), and it’s a little clean but nothing to get excited about. The water’s sitting at 80°, which is just a touch cooler than average for this time of year – not a big deal.
The real standout is Monday morning the 24th. That’s your call-to-action. Omaezaki is a beach and reef setup, and we’ve got a glassy, clean morning with a 3 ft SSE swell but a super long 18-second period. That’s proper groundswell, with combined energy surging to 1079 (moderate energy). For a beginner-friendly break like this, that long period will create nice, lined-up waves. The glassy wind makes it a winner for experienced surfers who know how to handle a long-period swell at a spot like this – it can make the waves stand up a bit steeper.
Tuesday the 25th and Wednesday the 26th see the swell building to 8 ft and 8 ft, but the wind is onshore and messy. The energy is strong (2588 and 1986), but the conditions are marginal. It’s too big and choppy for a good session here.
Thursday morning the 27th is another highlight. The swell drops to a clean 5 ft from the SW, with a moderate 11-second period and glassy conditions. Combined energy sits at 766, and it’s shaping up for very good surf. This is your second-best window.
The swell drops off into the end of the month, with Friday the 28th being a write-off. Saturday the 29th and Sunday the 30th have some small, clean waves in the 3 ft to 4 ft range, with offshore NE winds on Saturday afternoon and Sunday morning. The energy is low (around 311-360), but the conditions are clean for a longboard or a fun board.
Then we hit the first week of September, and it gets interesting again. Tuesday the 1st and Wednesday the 2nd bring back a solid 6 ft to 7 ft S swell, with 13-14 second periods and offshore to cross-off winds. The combined energy jumps to 1254-2137 (moderate to strong). This is excellent surf for experienced surfers – the waves will have push and shape.
Thursday the 3rd has an 8 ft SSW swell with a 14-15 second period, energy up to 3457. The winds are cross-off and clean, but it’s getting toward the upper limit for comfort at this break.
Friday the 4th is a big red flag for this spot. The swell hits 10 ft to 12 ft from the SSW, with 14-second periods and very strong offshore winds (22-25 mph). The energy is massive (4085-6435). The data says the wind and tide are favorable, but the swell is predicted to be too big for Omaezaki. This is expert-only territory, and even then, it’s a beast. After that, Saturday and Sunday the 5th and 6th are blown out by strong winds and storms, with the swell dropping fast.
Monday the 7th brings it back down to a clean 4 ft to 5 ft from the SSW, with offshore winds and a moderate 11-second period. Combined energy around 572-641. It’s clean again and a good way to ease back in after the big swell.
Overall, the best on offer is Monday the 24th of August for the glassy, long-period groundswell, and then Tuesday and Wednesday the 1st and 2nd of September for the bigger, cleaner S swell. The 4th of September is a monster, but it’s just too much for this break.

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.
