The Lowdown
Alright folks, Rusty here with a look at the next 16 days for Suruga Bay. I've got the charts open, and honestly, it's a bit of a slow burner.
Right off the bat, the best window is this Monday morning, the 10th of August. We’ve got a nice 3 ft SW groundswell rolling in at a quality 11 second period. The water is sitting at 81°, bang on average for this time of year. But the real story is the wind – or lack of it. Glassy conditions, dead calm. That makes for a super clean morning at the breakwater. The combined energy is moderate at 392, so there's enough push to have some fun on a longboard or a funshape. It’s very consistent here and being a beginner-friendly break, Monday morning is your standout. Just a heads up, it can get busy here sometimes, so grab it while it's clean.
Things go downhill pretty fast after that. Monday afternoon the wind swings cross-shore and picks up to 9 mph from the SSW, turning it into a bit of a bumpy mess. Then from Tuesday the 11th right through to the end of the weekend on the 16th, it’s a pretty grim run. We’re looking at a mix of onshore slop, cross-chop, and dropping swell energy with mostly poor conditions. You'll see the combined energy drop from the low 200s down to around 100 (130 to 146 range), which is weak to moderate. Very ordinary.
There are a couple of tiny windows where it cleans up. Saturday the 15th morning has a clean, light cross-offshore wind from the NNE, but with only 1 ft of swell and very weak energy at 129, it's barely going to break. Similarly, Sunday the 23rd morning looks glassy, but again, we're talking about 2 ft of weak energy (80). Not much to get excited about.
Looking a little further out, there is a flicker of hope around the start of the second week. Late on Saturday the 22nd, we get glassy conditions again with a 2 ft S swell and a period of 9 seconds, with combined energy just creeping back up to 100. It’s surfable but very ordinary. After that, it's back to poor conditions with very weak energy readings in the 50s and low 80s. Swell direction wants to be from the SE for optimum shape, and while we see a bit of SE wind on the 18th morning under glass, the swell period drops to a dismal 4 seconds and the energy falls to just 39.
So, the bottom line: Monday morning is the clear winner. If you can’t get out then, there’s a long, quiet stretch ahead with only a few clean but extremely small windows. For this area, a quiet run like this isn't totally unusual.
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.
