The Lowdown
Alright, let me break it down for Suruga Bay. We’ve got a long stretch ahead, and to be honest, it starts off pretty flat and frustrating.
Your first real chance to get wet is Thursday morning, September 3rd. The swell is tiny, only about 2ft from the south with a short 8-second period. The combined energy is weak (85), so it’s barely moving. The wind is glassy though, so the surface will be clean, but it’s really only a beginner longboard wave. Not a standout by any means.
Friday morning the 4th is a touch better. You get 3ft from the south, a slightly longer 10-second period, and moderate energy (163). The glassy morning conditions will make it look nice, but the waves are still small.
Then it gets grim. From Saturday, September 5th all the way through the middle of the month, the wind turns nasty – mostly cross-shore or onshore, often blowing hard. The wave heights jump around, but the quality is consistently poor. Saturday the 5th brings 5ft of short-period, wind-blown mess, and it only gets uglier. There’s a big spike on Wednesday, September 9th, with a solid 10ft swell from the south carrying strong energy (2446), but it’s hammered by cross-onshore winds and storm risk. That’s not for paddling; that setup looks more interesting for kite surfing. This poor run will last over a week.
Finally, we see some hope near the end. On Thursday morning, September 17th, there’s a clean 3ft swell from the SSE, but with a very long 15-second period. The energy is strong (490). The wind is cross-offshore and clean. This is a true groundswell, and for Suruga Bay, that long period can mean better shaped waves, though it might make things break a bit straight. It’s a promising but less certain long-range call.
But the real standout is Friday morning, September 18th. The swell is 6ft from the SSE, still with that excellent 15-second period. The combined energy jumps to (1537), which is strong. The wind is light and cross-shore, which is as good as it gets here. This is the best wave of the whole outlook. It’s a proper size for a fun session, with real power from that long period. It’s worth the wait.
For this area, a long run of poor conditions like this isn’t unusual. Keep your eyes on that Friday the 18th – it’s the only true highlight.

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.
