The Lowdown
Alright, let’s get into it. The outlook for Suruga Bay is a bit of a mixed bag over the next couple of weeks. We’ve got some solid swell on the way, but the wind is going to be a real issue for much of the period, keeping things on the messy side. The water temp is sitting at 82°F, which is pretty much bang on average for this time of year, so no surprises there.
The first real chance for a wave comes in on Wednesday morning, August 5th, with a 7ft SE swell, but it’s a bit of a letdown. The wind is a cross-shore NE breeze at 16 mph, and the combined energy is moderate (2382). The conditions are marginal, with a cross-chop making it rough. This isn’t the day to get excited.
Thursday, August 6th, the swell pushes up a bit to 8ft from the SSE, but the wind switches to a cross-on ENE breeze. The energy is a bit stronger (2312), but the chop is still there, making it a tough paddle. By the afternoon, the wind goes fully onshore, and the conditions drop to zero. Not worth it.
Friday, August 7th, sees the biggest swell of the early window, a 10ft S swell with a 14-second period. That’s solid groundswell, and the energy is strong (3455). But the wind is a cross-on E breeze at 12 mph, and the report says it’s marginal. The afternoon turns into a full-on onshore mess with 19 mph winds. This one is a real tease – the swell is there, but the wind is going to ruin it. If you’re an expert and you can handle some chop, it might be worth a look, but it’s not the clean, lined-up wave you’re hoping for.
The weekend and into the next week, we see a drop in size. Swells hover around 6ft to 7ft from the SSW, but the wind pattern stays stubborn. Mornings offer cross-shore winds, which are the best of a bad lot, but the afternoons are consistently blown out. The energy drops from moderate to low as we go, hitting around 1287 by Tuesday, August 11th.
Now, there is one standout. On the morning of Thursday, August 13th, we get a rare moment of magic. The swell is a modest 4ft from the SSW, with an 11-second period, and the combined energy is low (429). But the wind is dead calm – glassy conditions. The report says “expect good surf conditions.” For this break, that’s the best on offer in the whole 16-day window. It’s a small, clean wave, perfect for a beginner or someone wanting a longboard, and the calm wind means it’ll be smooth as butter. The crowds are “sometimes” an issue here, so it might be a bit busy, but for a session like that, you won’t care.
After that, it’s a long dry spell. From Friday, August 14th, right through to the end of the outlook on Thursday, August 20th, the surf is poor. Swells drop to under 3ft, periods shorten, and the wind stays onshore or cross-on. The energy readings are all under 1000, often in the low hundreds. There’s nothing to recommend. Even the bigger 4ft swell on the 18th and 20th is ruined by onshore winds.
So, to wrap it up: the whole period is a struggle with wind, but keep your eyes on the morning of Thursday, August 13th. That glassy session with the 4ft SSW swell is the only true standout. For the rest of it, you’re better off waiting for the next forecast update.

Information about the Suruga Bay Surf forecast
The above surf forecast table for Suruga Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Suruga Bay can be found by selecting the local surf guide option on the grey menu. Our Suruga Bay 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 (Suruga Bay) 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 Suruga Bay 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.
Suruga Bay is 6 km (4 miles) from the city of Sagara. If you plan a holiday in Shizuoka, look for hotels and other accommodation in Sagara. Sagara has rooms for a wide range of budgets as well as car hire and transport links.
