The Lowdown

Alright folks, Rusty here with a look at the surf ahead for Suruga Bay. Gotta be straight with you—this is a classic tale of two halves. The next week and a half is pretty flat and messy, but if you can wait, there’s a serious pulse of energy lining up for the final weekend and into the next week. Hold tight.

The first real action worth paddling out for is on Tuesday morning, September 8th. We’ve got a clean 5ft south swell rolling in with a 9-second period, producing moderate wave energy (443). The wind is glassy out of the east at just 3 mph, so conditions will be smooth. The water temp is sitting at 81°, which is pretty much bang on average for this time of year, so don’t stress about a wetsuit. This is the only real highlight for days, and it’s a short window.

After that, things fall apart quickly. From Tuesday afternoon right through to Saturday, September 19th, it’s a long, grim stretch of weak, wind-affected waves. Swell drops below 3ft, periods get short and periods of onshore and cross-shore winds dominate, leaving the bay choppy and uninviting. There’s a run of ten days where you’re better off doing something else.

But then everything changes. Sunday, September 20th kicks off a proper late-season groundswell event. Sunday morning brings glassy conditions with a 3ft swell, but don’t let the size fool you—the period is a massive 21 seconds, and the energy is strong (843). By Monday, September 21st, it gets serious. The swell jumps to 7ft out of the southeast with an 18-second period, absolutely cranking (3384 energy). The wind is light cross-offshore in the morning and glassy calm by Monday afternoon. This is excellent, powerful surf, but at over 8ft combined with that long period, this is strictly for experienced surfers—this break will be thumping. The deep water groundswell will unload with authority. Expect a crowd, as this spot does get busy when it’s on. This is the true standout of the whole outlook.

Tuesday, September 22nd hangs in there with a solid 6ft swell and glassy conditions in the morning from the west. Still plenty of grunt (1808 energy) and a long 16-second period for more great waves, but again, that size is in the expert zone.

That’s the window. By Wednesday, September 23rd, it fades back into small, wind-blown junk. So, if you’re in Suruga Bay, save your energy for that September 20th to 22nd window—the Monday the 21st is the day to circle on the calendar.

Stay sharp, keep an eye on the sky.
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.
