The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming down the pipe for Suruga Bay.
The next week and a half or so is a proper struggle. The bay is mostly under the pump with poor quality, onshore winds and just not enough energy to get excited about. There’s a gap right out of the gate with nothing worth chasing for the first five days, from Sunday August 9th right through Thursday August 14th. The swell is small, the wind is messy, and you’d be better off doing something else. It’s not until Friday August 14th morning that we see a glimmer, but it's still ordinary with just 2ft of SSW swell and glassy conditions – surfable if you’re desperate, but hardly a standout. Saturday August 15th morning is more of the same glassy calm, but again weak with 2ft. Monday August 17th morning offers another glassy window but the swell is dropping to just 2ft.
The real standouts don't arrive until the second week. Keep your eyes on the morning of Saturday August 22nd, but it's still a tricky call. The swell jumps up to 5ft from the S with a long 13-second period – that’s proper groundswell energy (677 combined energy), but the cross-shore wind and questionable tide could mess with the shape. The afternoon picks up even more size, 6ft from the SSW, period 12 seconds, and a whopping 1082 in energy – that’s strong stuff. It is going to be too big for beginners and only suited to experienced surfers. The wind is onshore though, so it’s going to be hard work at the beach break.
Then Sunday August 23rd is the best bet across the whole outlook. The morning and afternoon both show 5-5ft of SSW swell, period 12 seconds, and for the first time, clean conditions with a light cross-offshore wind from the west. The energy sits at 701 and 628 – solid, powerful. That’s the session to pencil in. The swell direction is from the SSW which matches the optimum SE direction for the break about as close as we'll get. This is a point break and reef setup, so that long period swell will really stand up and wrap in, giving you proper shaped waves. It’s a rare moment of quality.
So overall, it’s a long flat stretch to start, then a big pulse late in the window. The standout is definitely Sunday August 23rd, with Saturday August 22nd being a close second if you’re an expert after big, raw energy.
Catch you out there.

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.
