The Lowdown
Alright, Rusty here, let’s have a look at what’s coming our way.
First off, the honest truth: we’re in for a tough stretch. For the next week and a half, there’s really nothing to get excited about. The surf is small, the wind is messy, and most days are straight-up poor. From Tuesday the 8th through to the 20th, it’s a long, flat, and choppy grind. There are a few swells, but they’re married to onshore or cross-shore winds that ruin any chance of a decent wave. The water temperature is about average for this time of year over at Suruga Bay, but that’s about the only thing that’s cooperating.
The highlight of the whole forecast is the morning of Monday the 21st of September. That’s our standout. Suruga Bay is the only break on report, and it finally shows some life. We’ve got a 4ft swell from the SE, with a solid 16-second period. That’s proper groundswell energy, and it’s packing a combined energy of 912 (moderate wave energy). The wind is light and cross-offshore from the NNE, which should keep the surface clean. This is the best window we’ve got, and it’s worth marking on the calendar. The swell size is small enough for beginners, but the long period will give it some shape at this breakwater setup.
Tuesday the 22nd keeps the energy going, but it’s a bigger step up. The swell pushes to 6ft from the SSE, still with a long 16-second period, and the combined energy jumps to 2026 (strong wave energy). That’s a lot of water moving around. The wind is light and cross-shore from the NE in the morning, so it might be clean enough for experienced surfers, but at that size, it’s not for the faint-hearted. The crowd profile is marked as “sometimes”, so you might have some company, but it’s not a zoo.
Into Wednesday the 23rd, the swell maxes out at 8ft from the SSE, with a 17-second period and a combined energy of 3185 (very strong wave energy). That’s big, powerful swell, and only for experts. The wind is a gentle cross-shore from the NE, which could make it manageable, but it’s a serious step up. The direction is a match for the optimum swell direction for the break, so the waves should have some decent lines.
Bottom line: this is a long wait for a short window. The 21st morning is the clear winner if you’re patient. The 22nd and 23rd are for the big-wave crew only. The rest of the 16 days is a write-off. Stay tuned, forecasts can change, but right now, it’s a quiet spell.
Rusty.

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.
