The Lowdown
Alright, let’s get into it. The long-range picture for Omaezaki (beach and reef) is a real mixed bag. We’re looking at a promising run of solid swell from around Monday the 7th, but it’s followed by a dry spell that stretches all the way from the middle of the month to the end of the outlook. The first few days are small and wind-affected, so it’s a case of waiting for the good stuff to arrive.
Saturday morning, the 5th, kicks off with a small 4 ft SSW swell, but it’s bumpy with a moderate breeze. The break is fairly consistent overall, and the crowd can be around sometimes. The water temperature is about average for this time of year.
Sunday the 6th is a write-off. The swell drops to 1 ft with a howling near-gale offshore. You’d be fighting the wind just to stand up, not worth it.
Then Monday the 7th is where it starts to get interesting. Monday morning brings a 8 ft S swell with a 10-second period and moderate offshore wind. The combined energy is strong (1759), so you’ll feel the power. This is clean and punchy, but at this size it’s for experienced surfers only. Monday afternoon pushes up to 10 ft, which is too big for this setup, so the morning is the pick.
Tuesday the 8th keeps the energy high. The morning session has a 8 ft SSE swell, light offshore breeze, and combined energy of 1346. Again, this is for experienced crew only, but the conditions are excellent.
Wednesday the 9th offers a slight drop in size to 7 ft from the S, but the real treat is the glassy conditions in the morning. Light wind, clean surfaces, and moderate energy (700) – this is a window for the stronger paddlers.
The swell begins to ease through Thursday and Friday, with the 10th and 11th seeing 5 ft to 7 ft, but the wind turns cross-shore or onshore, making it messy. The energy drops to moderate levels.
By Saturday the 12th, the swell has dropped to 2 ft from the ESE, but the period jumps to 14 seconds. That’s a very long-period groundswell – it’ll be clean and glassy, but those waves will be very lined up and straight. Omaezaki being a beach and reef, it might not be the best fit for that kind of swell. Still, a calm morning makes it a goer for a log.
Sunday the 13th has a glassy start with a 5 ft E swell, but the period is short at 7 seconds, so it’ll be a bit weak and crumbly.
Monday the 14th is the last real standout. Morning sees a 6 ft E swell with a light offshore breeze and clean conditions. Combined energy is 897, so moderate but solid. The afternoon holds up with 4 ft from the ESE and a 10-second period, still clean. This is the best of the second week for a regular surfer.
From Tuesday the 15th onward, it’s a slow fade. The swell drops below 3 ft, and the wind turns onshore or glassy but with tiny, weak waves. The energy readings fall into the low hundreds, then to double digits. From the 17th to the 20th, it’s a flat spell with no real surf to recommend – just poor conditions day after day. That’s a long gap of nearly a week with nothing going for it.
For the best surf in the whole period, I’d call Monday morning the 7th as the standout. That 8 ft S swell, moderate offshore wind, and serious energy is the pick of the lot. Tuesday morning the 8th is a close second. After that, Monday the 14th is your best bet in the second week, but it’s smaller and softer.
Signing off, 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.
