The Lowdown
Alright, folks, Rusty here. Let’s get straight into it for Suruga Bay.
Looks like the next week and a half is a bit of a mixed bag here. The first week is packing some serious size, but the wind is a real problem for most of it – we’re dealing with a lot of cross and cross-onshore winds that will keep things messy. There’s a lot of energy in the water, but the quality is going to be poor for paddle surfing until we get a break in the conditions.
The swell is coming in with a very long period at 17 seconds, which is a classic groundswell. That kind of period means better shaped waves, but at a beach break like Suruga Bay, it can make the waves break a bit too straight. The combined energy is massive – we’re talking values in the thousands (1740 on Tuesday morning, building to over 5000 by Sunday). That’s strong to very strong wave energy, but the wind is ruining it.
The water temp is sitting at 81°F with a tiny anomaly of 0.3°F, so it’s right on the money for this time of year – warm, comfortable.
The real standout here is the morning of Tuesday, August 11th. The wind drops to nothing – glassy conditions – and the swell is still a solid 6ft from the SSW at 14 seconds. The combined energy is 2283, which is still strong. The waves will be clean and powerful, but at this size, it’s getting into the territory for experienced surfers only. The crowd profile says "sometimes," so you might have a few heads out, but with conditions that good, it’ll be worth the paddle. The afternoon of the same day also looks glassy with a 5ft SSW swell, but the energy drops to 901, so it’s a bit weaker.
Before that, from Tuesday, August 4th through to Monday, August 10th, the surf is on the menu but the wind is consistently cross or cross-onshore from the ENE and ESE, with speeds between 9 and 19 mph. The swell height builds from 5ft up to 10ft, and the period is long (15 to 17 seconds), but the chop will be ugly. The comments are all "marginal" or "poor." This is really a kite surfer’s window – the wind is strong and the swell is there, but for a paddle board, it’s going to be a battle.
After the glassy Tuesday, things go downhill fast. From Wednesday, August 12th onwards, the swell drops below 4ft and the wind picks up again, mostly from the NE with moderate to fresh breezes. The combined energy falls to a few hundred, and the comments are all "poor" or "marginal." That’s a dead zone for quality surf. You’re looking at a gap of nearly a week with no real options from that point on.
So, to sum it up: the best bet is the morning of Tuesday, August 11th. It’s the only window where the wind cooperates with a decent swell. Before that, it’s a lot of energy with poor conditions, and after that, the surf fades out.
Stay stoked, 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.
