The Lowdown
Okay, folks, let's be real. Suruga Bay is looking pretty damn lean for the next two weeks. We're talking a long stretch of small, junky surf. From now until the 26th, there is a lot of nothing on the table. You'd be hard-pressed to find a wave with any push, and most mornings are just bumpy and cross. The swell energy is weak, with combined energy readings mostly in the double digits, barely hitting the 100s on a good day, like on the 14th (103) or the 15th (122). It's just weak, disorganized slop.
Now, there is a light at the end of the tunnel, and it's the afternoon of Wednesday the 26th. That's the standout. The swell jumps to 5ft, coming from the SSE, with a period of 12 seconds. The energy will be strong, hitting 805, which is a massive jump from what we've been seeing. This is the one. It's still got a bit of onshore wind, but there's real power in this swell. The morning of that same day is also worth a look, seeing a bump to 3ft with a similar long-period SSE swell, but the afternoon has the size.
For that afternoon, keep your eyes on Suruga Bay. It's a breakwater setup and it's very consistent, which is good. The swell is coming from the SSE, which isn't the perfect SE angle, but it's close enough to get some waves breaking. At 5ft, this is getting too big for the beginners, but it's not a monster. It'll have some serious push.
Water temp is 82°, which is about normal for this time of year, nothing special.
So, the plan is simple: the next two weeks are for tuning your board and watching the cams. Then, mark your calendar for the 26th. That afternoon looks like our one real shot at some proper waves. It's a promise, not a certainty, but it's all we've got.

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.
