The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s on offer.
Alright, straight up – this is a tough run for Suruga Bay. We’ve got a solid pulse of swell kicking off the first few days, but the wind is just not playing ball. There’s a bit of a wait for the really clean stuff.
We start on Thursday, 6th August, with a serious amount of energy in the water – the combined swell energy is a hefty 2371, which is strong. That’s a 8ft swell from the SSE with a 14-second period, a proper groundswell. But the wind is a cross-on from the ENE at 12 mph, making it choppy. The water temp is 81°, which is about average for the time of year. For a beginner spot, this is already too big and messy, and the afternoon goes onshore, completely killing it.
Friday the 7th is more of the same, with a 8ft S swell, but still cross-on wind. The energy drops a little but remains strong. By Saturday morning, the swell drops to 6ft from the SSW, but the wind is still cross-on, making it only marginal.
Now, here’s where it gets interesting. The real standout for the whole forecast is Monday morning, 10th August. The wind goes glassy, flat calm, with a light ENE breeze of 3 mph. The swell is small, only 3ft from the SW with a 12-second period, but the combined energy is moderate (474). That glassy wind will make for some clean, glassy little waves. It’s not big, but it’s the best quality you’ll see. The break is a breakwater, so that long-period groundswell should line up nicely.
Tuesday morning, 11th August, also sees glassy conditions with a 3ft SSW swell, and again, it’s the cleanest option. The surf is small, but the conditions are perfect.
Wednesday morning, 12th August, is another glassy morning with a 4ft SSW swell. The energy is moderate (333). This is another great window for a small-wave session.
After that, the swell fades away. From Thursday afternoon, 13th August, through to the end of the forecast on 21st August, the surf is mostly poor or very small, with a lot of onshore and cross-shore winds. There are a few glassy moments, like on Tuesday morning, 18th August, but the swell is tiny (1ft) and the energy is weak (61). Not worth a drive.
The best surf on offer is without a doubt the glassy mornings of Monday 10th, Tuesday 11th, and Wednesday 12th August. The waves are small, but the conditions will be perfect. If you’ve got a grovel board, that’s your window.
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.
