The Lowdown
G’day, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty flat and ordinary for Suruga Bay. We’ve got a long stretch of small, messy, onshore slop ahead, so if you’re hanging for a wave, you’re going to need some patience. The first week is a write-off, honestly. There’s a lot of cross-shore chop, light onshore breezes, and barely enough swell to push a sea gull around.
The action, such as it is, doesn’t even start to show a pulse until the second week. We’ve got a real long period swell arriving on Monday the 24th of August, with chest to head high waves at 3.6ft – that’s the standout size-wise. The energy is there too, with a combined swell energy reading of 700. You can feel that in the water. But the wind is going to be a bit of a hassle, blowing cross-onshore and making things a little lumpy. It’s surfable, but not pretty.
Now, if you can hold out for the real gem, that’s Wednesday the 26th of August. The wind goes glassy in the morning, the swell is a clean 3ft from the ESE with a solid 13-second period, and the energy reading is a healthy 265. This is the one to point the car at. The direction is lined up nicely, it’ll have some push, and with no wind on it, the surface will be proper smooth. It’s still small for the experts, but it’s clean, and that’s a big win after this run of junk.
Beyond that, the end of the month just fades out again, so keep your expectations low. There’s a heap of days in a row with nothing on offer, so don’t get too excited about the long range.

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.
