The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Suruga Bay.
We’re looking at a pretty quiet start to the forecast period. The first few days are a write-off with tiny onshore chop, so don’t bother paddling out just yet. The real action starts to build from Monday morning, the 24th of August, when we get a nice clean pulse of groundswell.
The standout window is the morning of Monday the 24th. We’ve got a solid 3ft SSE swell rolling in with a very long period of 15 seconds – that’s a proper groundswell. The wind is glassy, dead calm, so the surface will be like a mirror. The water is sitting at 80°, which is pretty much bang on average for the time of year, so no wetsuit needed. The combined energy is a moderate 488, but the quality of the wave will be way better than that number suggests. This is the best chance for a clean, lined-up wave at Suruga Bay for the whole outlook. Just keep in mind, with a period that long, the sets might be a bit spread out, and it could be a bit straight on the beach, so look for a sandbank that’s working.
The swell builds through the middle of the week, but the wind gets messy. On Tuesday the 25th, we’re looking at a 8ft to 8ft S swell with a 15-second period – that’s serious energy (2339) and will be too big for beginners. The problem is a moderate cross-shore wind, which will chop it up. This is definitely expert-only territory.
By Wednesday the 26th, the swell drops back to 6ft, still with a long period, but the wind is still cross-shore and a bit lighter in the morning. It’s a better window for experienced surfers, but it’s not a standout.
After that, we see a steady drop in size and quality. The wind shifts around, and the surf becomes marginal with poor conditions through the rest of August and into September. There’s a couple of days with clean-ish cross-offshore wind, but the swell is too small and weak to really get excited about. The energy drops hard – into the 100s and 200s – and the wind ramps up, including a strong breeze and risk of thunderstorms on the 6th of September. That’s a day to stay well clear of the water.
The last week of the outlook is a bit of a bust. The swell is small and the wind is mostly onshore or cross-onshore, so it’s going to be a frustrating run of closeouts and wind chop. For the committed surfer, the Monday morning of the 24th is your only real call.
Stay patient, and keep an eye on the charts.
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.
