The Lowdown
G’day, Rusty here. Let’s have a look at what Suruga Bay is serving up over the next couple of weeks. Right now, we’re in a flat spell. There’s nothing worth paddling out for from Wednesday the 19th through to Sunday the 23rd of August. Those first few days are tiny, messy, and the wind is all wrong – just small wind ripples and chop. A real nothing burger.
Monday the 24th sees a pulse of long-period groundswell start to show, with a 15-second period from the SE. The combined energy is moderate (359). The wind is light and onshore, though, so it’s not clean. Still, it’s a hint that something is building. Tuesday the 25th is where things get interesting. We’ve got a solid 4ft swell from the SSE, with a long 14-second period. The combined energy jumps to strong (1178). The morning has light cross-onshore winds, keeping it a bit lumpy, but the size and power are there. For a beginner-friendly spot like this, that’s pushing the upper limit for a comfortable session, but the consistency is very consistent here, so there’ll be waves.
The real standout is Thursday the 3rd of September. After a run of big, messy surf that’s simply too large for this break, we finally get a sweet spot. The morning has a clean 7ft swell from the SSW, with a 13-second period. The combined energy is very strong (1559). But the magic is the wind – light cross-offshore from the NNE. That means clean, lined-up waves. This is the best on offer across the whole outlook. It’s big enough to be fun for experienced surfers, but at a breakwater setup, that longer period should help it reel off nicely. Crowds are possible here sometimes, so get in early.
A quick note on the water: it’s sitting at 81°, which is about average for this time of year – no surprises there.
Before that, the swell runs huge from Wednesday the 26th through to the end of the month, with combined energy readings over 4000 and waves up to 13ft. That’s expert-only territory, and the wind is often onshore or cross-onshore, making it a sloppy, powerful mess. Honestly, that setup looks more interesting for kite surfing than paddle surfing. Avoid it unless you’re a pro and don’t mind the chop.
So, to sum it up: the first week is flat or poor. Tuesday the 25th is a decent warm-up, but Thursday the 3rd of September is the one to circle on your calendar. Clean, solid, and with that offshore tick – that’s your session.
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.
