The Lowdown
Alright folks, Rusty here. Let's get into it for Suruga Bay. It's been a quiet stretch, but there's some serious potential brewing out there if you're willing to wait for the right moment.
The next week is a bit of a write-off, to be honest. We've got a gap of several days with nothing worth paddling out for. From Friday the 21st through Sunday the 23rd, it's just poor conditions – weak, short-period swell and cross-shore winds chopping everything up. You're looking at tiny 2ft to 2ft waves with combined energy that's barely a whisper (between 69 and 119). Not worth wetting the wetsuit for.
Monday 24th sees a shift, a pulse of longer-period swell starts to show, but it's still messy. The morning has 4ft from the SSE with a long 17-second period, moderate wave energy (1265), but the wind is onshore. It's a marginal call at best.
Now, Tuesday the 25th is the first real standout. Tuesday morning at Suruga Bay is where you want to be. We’re looking at a solid 8ft groundswell from the south, an impressive 15-second period, and the total wave energy is pumping at 3220. But the kicker? The wind is glassy. Flat calm. For a breakwater spot, that offshore-optimum SE direction is a dream, and this south swell lines up nicely. This is going to be *clean*. Paddling out will be easier with those long gaps between sets, and the shape should be excellent. That said, at 8ft, this is expert territory, so don't send the beginners out. The water temp is sitting at 80°, a bit colder than normal for this time of year, so you won't need a steamer but maybe a light spring suit if you're feeling it.
Wednesday the 26th morning keeps the quality going with another glassy session, 7ft from the south and a 13-second period. Still solid, still clean, still for experienced surfers.
We then get a bit of a lull again until we hit Thursday, September 3rd. Mark this one, folks. Thursday morning is looking exceptional. We've got a pumping 10ft groundswell from the ESE, with a massive 19-second period. The combined energy is through the roof at 5579. And again, the wind is glassy. The guidance says it's for expert surfers, and at 10ft, that's a no-brainer. The direction is a little off the optimum for the break, but with that kind of period and energy, it's going to push through and produce some serious, powerful lines. This is the big one. The afternoon gets even bigger at 12ft but with light onshore wind, making it a bit too much and a bit blown out for this break.
That's the story. A couple of standouts for the experts in the coming weeks, but a long, slow start.
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.
