The Lowdown
Alright folks, Rusty here with a look at what's coming our way.
To be straight up, the next week and a half is pretty flat for us. We’re looking at a big stretch of weak surf, with a real tease of some proper energy way out at the end. From now until around the 24th of August, you'll be lucky to find a ripple. The swell is tiny, mostly under 2ft, and the wind is all over the shop. There’s a few glassy moments, like Thursday morning the 20th of August, but with a 0.7ft swell, it's not worth paddling out for. Don't bother getting the wetsuit wet.
Now, the real story starts to build late in the month. The 25th of August shows a pulse of energy, but it's messy and cross-onshore. Keep watching though, because the 28th of August is the day. The morning of Friday, the 28th of August, is shaping up as our one true standout. After all that waiting, we’re looking at a solid 8ft swell from the S, with a long period of 16 seconds. This is proper groundswell energy, with a combined energy of 3103, and the wind is light and offshore from the NNE. The report calls for clean conditions. This is big, powerful stuff - over 8ft is for experienced surfers only. You’ll want to be on your game. Given the long period and solid size, Suruga Bay (Suruga Bay) will hold it best. It’s a breakwater set-up and it’s exposed. A swell from the S is close to the optimum SE direction. Crowds are sometimes an issue here, so get in early.
After that peak, the swell starts to drop but stays rideable through the weekend. The morning of the 29th of August has a 7ft SSW swell, but the wind swings cross-on. Still good for those who know what they’re doing, but that Friday morning is the gold.
So, a long, flat wait, then one very promising day for the experienced crew.

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.
