The Lowdown
Alright, let’s get into it. We’re looking at Suruga Bay. The surf kicks off this Saturday morning, the 8th of August. There’s a solid swell arriving, but it’s a bit of a mixed bag as we go through the period.
The standout session is hands down Saturday morning, August 8th at Suruga Bay. We’ve got a 5ft south swell rolling in with an 11-second period, which is proper groundswell. The wind is glassy, just a light easterly, which means the surface will be clean. The combined energy is moderate, sitting at 663, and the water is a warm 80°, which is about average for this time of year. This is beginner-friendly in size, but the quality will be there for everyone. Expect some crowds, though, as it’s a spot that can get busy.
The afternoon on Saturday sees the wind swing cross-onshore and the surf quality drops off fast. Sunday is small and messy, with only 3ft and onshore winds.
Monday morning, August 10th, offers a brief window. The swell drops to 3ft from the SW, but the wind goes glassy again with a light SE breeze. The period is a solid 12 seconds, so the waves will have some shape. The energy is moderate at 435. It’s a mellow option, better for the longboard or a fun log.
From Tuesday, August 11th, through to Friday, August 21st, the surf is mostly poor. We get a lot of cross-shore and cross-onshore winds, with chop and lumpy conditions. The swell stays small, between 2ft and 3ft, and the energy drops off significantly. There’s a long stretch of very ordinary days here.
There’s a flicker of hope on Saturday morning, August 22nd. The swell bumps up to 4ft from the SSW, with a 10-second period. The energy climbs back to 269. But the wind is a moderate cross-shore from the NE, so it’ll be bumpy. Not the best, but it’s the biggest swell we’ve seen in a while.
The rest of the window into the 23rd stays small and unappealing.
Bottom line: The call is for Saturday morning, August 8th. That’s the one to clear your schedule for. After that, it’s a long wait for any real quality.

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.
