The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Suruga Bay over the next couple of weeks. Gotta be straight with you – it's a bit of a mixed bag, and we've got a long wait for anything worth paddling out for.
For the first week, from now through to the 23rd of August, it's basically flat. We're looking at tiny, weak dribbles of swell, none of it breaking past knee-high. The wind is mostly onshore or cross-onshore, making a mess of any ripple that shows up. The combined swell energy is barely registering, often below 100, which is as weak as it gets. Honestly, there's nothing doing. You're better off finding something else to do.
Now, things start to get interesting from Monday the 24th. A serious groundswell builds in. Early in the week, the surf at Suruga Bay turns on with a punch, but it's not for everyone. Monday afternoon sees a solid 5 ft swell from the SSE, with a period of 17 seconds. That's a long-period groundswell, which means proper energy and good shape, but it's prone to closing out here. The combined energy is a massive 1625. However, the wind is a cross-shore breeze, which will keep the faces bumpy. This is more of a promise of what's to come.
The real standout of the entire forecast is Wednesday, 26th August. The morning session at Suruga Bay (Suruga-Bay) looks like our best bet. We're talking a 8 ft swell from the south, powered by a deep 14-second period. The combined swell energy pumps at 2124. But the kicker is the wind: light ESE at just 3 mph, which is a light cross-onshore, but essentially glassy with only small wind ripples. That's about as clean as it gets for a surf this size. Just be aware, at 8 ft, this is serious, expert-level wave height. Beginners, stay on the beach for this one. The water temp is sitting at 81°, which is about average for this time of year, so you'll be fine in boardshorts.
The energy hangs around for a few days, but the wind quality goes downhill. Thursday the 27th sees a similar 8 ft swell, but the onshore wind from the SE will chop it up. By Friday the 28th, we’ve got a massive 10 ft swell from the south, with combined energy over 2134. That's a beast of a wave and will be way too big for most. The wind is light cross-onshore, so it’ll be messy but powerful. This would be a spectacle to watch rather than surf for 99% of us.
As we roll into the second week, the swell drops off. The weekend of the 30th and 31st starts to fade. Then, on Monday the 1st of September, the forecast shows a huge spike. Monday morning predicts an enormous 15 ft swell from the SE, with an unbelievable combined energy of 11048. The notes say it's "too big for this break," and that's no joke. That's a death wish. By Tuesday the 2nd, it's still a chunky 8 ft but the wind is questionable.
So, if you've got the skills and the bottle, Wednesday morning, 26th August is your window. For everyone else, you might find a sneaky corner on the 24th or 25th, but don't expect perfection. The rest of the run is either flat, too small, or too big and blown out.
Keep your eyes on the horizon.
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.
