The Lowdown
Hey, Rusty here. Let’s talk about what’s happening in Suruga Bay over the next couple of weeks.
Right now? Nothing. Zero surf to speak of. You’re looking at a blank spell that stretches all the way to at least the 15th of September. That’s about five days of tiny, weak waves that aren’t worth suiting up for. The water is about 81°F, which is normal for this time of year. The first chance to paddle out on a real wave doesn't come until Tuesday morning the 15th, and even then it's just a weak 2ft SSE groundswell.
The one to circle on your calendar is the big swell arriving for the weekend of the 19th. That’s the standout. If you’re an experienced surfer, Saturday the 19th is your day. We get a solid 7ft SSE groundswell in the morning with a very long 16-second period (combined energy 2235). The wind is light and cross-offshore, keeping things clean. By the afternoon, it bumps up to 8ft from the SSE with a light offshore NNW breeze. That is the pick of the forecast.
Sunday the 20th is even bigger. We’re looking at a 10ft south swell in the morning, glassy conditions with no wind. By the afternoon, it’s still 10ft from the south with light cross-offshore winds. Remember, that’s a long-period groundswell (15-16 seconds), and it’s going to be heavy. This is for experts only. With that period and direction, it might not wrap in perfectly at a breakwater setup, so keep your eyes open.
Monday the 21st just gets enormous with a 13ft swell, which is too big to surf here. After that, the 23rd brings strong winds from a storm that will blow the lines out. It’s a short, powerful window but a good one if you’re after heavy, clean groundswell.

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.
