The Lowdown
Alright, Rusty here. Let's break down what's on the table for the coming weeks.
To be honest, the next week or so is looking pretty grim. From Saturday the 15th right through to Friday the 21st, we're staring at a wall of poor surf conditions. The water is sitting at 81.5°F, which is pretty much normal for this time of year – nothing unusual there. But the swell is tiny, weak, and the wind is just a mess, mostly cross-onshore or onshore. You're looking at combined wave energy mostly under 100 (149 max), which is just weak energy. Kites might have a bit more fun than surfers during this stretch because the waves are tiny and chopped up.
There's a real gap here, about a week of nothing special. We do get a tiny flicker of hope on Saturday the 22nd with a 3.6ft SSW swell, but it's still too messy to call it good. Then, finally, the real news comes on Monday the 24th.
That Monday morning is the standout. Suruga Bay (Suruga-Bay) is looking like the place to be. We've got a clean 4.3ft SE groundswell rolling in with a very long period of 16 seconds. That's proper energy – the combined energy hits 987 (moderate to strong). The wind is a light cross-offshore from the WSW, which is going to keep those waves clean and lined up. This is a beginner-friendly break, but with that long period, it might be a bit too straight for the beach, but the quality is there. This is the best session on offer, no question.
Monday afternoon drops off a bit, and Tuesday the 25th morning is still okay with a 3.3ft ESE swell, but the wind shifts around. After that, the surf starts to fade again into the following week with smaller, less energetic swells and a return to poor conditions. The 30th of August has a quick pulse of long-period energy (18 seconds, 327 energy) but it's too small and cross-on to be a real recommendation.
So, in short, the first week is a write-off. The one clear highlight is the Monday morning of the 24th. Mark it.

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.
