The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Omaezaki over the next couple of weeks.
Right off the bat, we’ve got a real quiet spell. The first recommendation isn’t until Monday the 24th, so that’s a solid four or five days of flat to pretty ordinary conditions. The early mornings around the 20th and 21st are tiny, with a bit of swell but it’s just not doing anything for us. Thursday the 20th morning is glassy, but the swell is only 1ft from the SE with a combined energy of just 51 – weak stuff. The wind is glassy, which is a tease, but there’s nothing to ride.
Friday the 21st and Saturday the 22nd see a bit more energy pick up, with swell heights around 3ft to 3ft from the SSW, but the wind is onshore or cross-onshore, and the periods are short at 9 seconds. The combined energy creeps up to 162 and 225 (still moderate), but the surf quality is poor. It’s just not worth paddling out for.
Sunday the 23rd is similar – a bit of swell, but it’s messy. The morning has a 3ft SSW swell with 8-second period and onshore wind. The afternoon sees a longer period swell of 14 seconds from the SE, but it’s only 2ft and cross-onshore again. Not the one.
Now, here’s the first real standout. Monday the 24th. The morning is looking special. Omaezaki (Japan) will see a solid 7ft swell from the SSE with a very long period of 17 seconds. That’s proper groundswell. The combined energy is a very strong 2646, and the wind is glassy – dead calm. This is going to be clean, powerful, and lined up. The water temperature is 79°, which is a bit colder than normal for this time of year, but nothing crazy. This swell is best for experienced surfers, though – 7ft with that period is pushing it for beginners. The long period can make the waves break a bit straight at a beach break, but Omaezaki is a beach and reef setup, so the reef points should handle it well. The afternoon is still good, but the wind goes cross-onshore, so hit the morning session.
Tuesday the 25th and Wednesday the 26th are for experts only. The swell is huge – 13ft to 15ft from the SSE and S, with periods around 15-16 seconds and combined energy readings of 7606, 7059, 5307. That’s massive energy. The wind is cross-offshore and clean, so the waves will be beautiful, but this is way too big for the average surfer. This is a big-wave session for the groms and the chargers. If you’re not a pro, stay on the beach and watch.
Thursday the 27th is still huge, but the wind turns cross-onshore and lumpy, making it a mess. Friday the 28th drops down to 6ft, but the wind is still cross-onshore and choppy, so the quality drops right off.
The end of the month and into September has some small, clean windows. Saturday the 29th morning is glassy again, with a 4ft SSW swell, but the period is just 9 seconds and combined energy is 310 (weak). It’s surfable, but nothing special. Sunday the 30th and Monday the 31st have a small 4ft to 5ft easterly swell with offshore winds, making for clean, small waves. The period is short at 6 seconds, so the waves will be a bit weak and crumbly. Good for a longboard or a foiler.
The first week of September is small and clean but ordinary. The wind stays offshore or cross-offshore, but the swell is tiny – 2ft to 3ft. The best of that period is Wednesday the 3rd, with a 4ft SSE swell and 11-second period, combined energy of 668 (moderate), but the wind is a fresh 19 mph offshore, which makes it clean but hard to paddle into. Thursday the 4th is a write-off: strong offshore winds up to 34 mph make it clean but impossible to paddle into, and the swell is all over the place.
Best on offer: Absolutely Monday the 24th morning. That 7ft SSE groundswell with glassy conditions is the clear winner. Get there early. The big stuff on the 25th and 26th is for the hardcore crew only.
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.
