The Lowdown
Righto, let’s have a look at what’s on the cards for Suruga Bay. This is a breakwater setup that’s very consistent and beginner-friendly, with an optimum swell direction from the southeast. The water temp is sitting at 82°, which is pretty much spot on for this time of year – feels like a warm bath, no need for a wetsuit.
The next week and a half is a bit of a write-off, to be honest. We’ve got a long stretch of nothing but poor surf conditions from Friday the 28th of August all the way through most of the first week of September. The waves are small, the wind is mostly cross or onshore, and the energy is weak. The combined swell energy hangs around 42 to 73 (weak) for most of that time, barely enough to get a wobbly pop. There’s a slight pulse on the 1st of September, with energy climbing to 148 (moderate), but it’s still cross-on wind and messy. It stays like this, with energy building to 324–346 (moderate) by the 2nd and 3rd, but the wind is still onshore or cross, so the quality is just not there.
The first real glimmer of hope comes on the morning of Friday the 4th of September. It’s glassy, with a 4ft south swell at 10 seconds, and the combined energy jumps to 301 (moderate). The wind is light and glassy – that’s the standout window for clean, fun waves. It’s not huge, but it’ll be clean and rideable, maybe the pick of the fortnight for a beginner wanting a nice, uncrowded paddle.
After that, it’s back to marginal conditions through the weekend and into the start of the week, with cross-shore winds and bumpy surf. The energy stays around 184–330 (moderate), but the wind just won’t cooperate.
Now, the real promise shows up in the second week. On the morning of Friday the 11th of September, the swell direction swings to southeast and the period jumps to 15 seconds – a proper groundswell. The combined energy rockets to 845 (strong), but the wind is a moderate cross-shore, so it’s going to be a bit choppy. Still, the size is there. By the afternoon of the 11th, the swell is 5ft from the southeast at 19 seconds (very long period), and the energy is 2386 (very strong). This is a serious swell, but it’s onshore winds, so it’ll be lumpy. For the experienced crew, this is when the bay could light up, but it’s not clean.
The biggest call is Saturday the 12th of September. Morning and afternoon both show a solid 10ft swell from the southeast, with a period of 17–18 seconds (very long period) and energy hitting 4594–4834 (very strong). That’s a huge, powerful groundswell. The wind is a gentle cross-onshore, so it’ll be bumpy, but for experts only. This is a big, powerful ocean, and at a breakwater, it’ll be a beast. The long period makes it best for a point or reef, but here it’s a breakwater, so expect it to wall up and close out in places. Definitely not for beginners. If you’re a kiter, this setup might be more interesting than paddle surfing, given the size and wind.
So, to sum it up: the best clean surf is the morning of Friday the 4th of September – glassy, 4ft, and fun. The big, powerful, expert-only swell hits on the 12th of September, but it’s bumpy and huge. Patient beginners will want to wait for that Friday the 4th morning.

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.
