The Lowdown

Right, let’s have a look at what’s on offer for Suruga Bay. Straight up, I’ve gotta be honest with you, the first week or so is pretty grim. There’s a big fat gap of nothing worth paddling out for from now through the rest of August and into the first few days of September. The wind is all over the place, mostly cross-onshore, and the swell is tiny – we’re talking knee-high slop at best. The wave energy is weak, barely hitting 60 or 70 (62), and that’s not enough to get excited about. You’d be better off staying home and waxing your board.

Come Wednesday morning, the 2nd of September, we get a little window. The swell is a pathetic 2 ft from the South with a period of 8 seconds, but the wind goes glassy. That’s the only thing saving it – it’ll be clean, but the waves are going to be weak and gutless. The wave energy is still feeble (66). I wouldn’t call it a session, more of a paddle to wet your hair.

The outlook doesn’t get much better until the 4th of September, Friday morning. We finally see a bump in energy, with the combined swell energy hitting 249, which is at least moderate. The swell is 3 ft from the South with a 11-second period, which is a proper groundswell. The issue? The wind is onshore, and the forecast is marginal. It’s a tease.

Now, the real talk starts on the 6th of September, Sunday morning. The swell jumps to 5 ft from the South, with a period of 15 seconds – that’s a very long-period groundswell. The combined energy rockets up to 1063, which is strong. But here’s the kicker: the wind is a fresh cross-shore at 19 mph, and it’s lumpy. This is a classic example of a swell that’s too big for the conditions. For a beach break like Suruga Bay, that long period will make it break too straight, and the wind will chop it up. It’s more interesting for kite surfers than paddle surfers, honestly.

The standout session, if you can call it that, looks like the 9th of September, Wednesday afternoon. The swell is 8 ft from the South with a 15-second period, and the combined energy is a massive 3705 – very strong. The wind is a gentle cross-shore at 9 mph, which is manageable. But with a swell that size, over 8 ft, it’s expert-only territory. The water temperature is about 82°F, which is basically normal for this time of year, so no worries there.

The 11th of September, Friday morning, is a write-off. The swell is 18 ft from the SSW with a 12-second period, and the energy is an insane 8420. The wind is a fresh cross-shore at 22 mph. The forecast actually says it’s too big for this break, and I agree. That’s a death wish. The afternoon is slightly better, with a 10 ft swell and a cross-offshore wind, making it clean, but it’s still a massive swell.

After that, the 12th and 13th of September look like a total washout, with near-gale-force winds and tiny, messy swell. The 14th of September is flat.

So, what’s the call? The best on offer is the 9th of September, Wednesday afternoon, at Suruga Bay. It’s a big, powerful groundswell from the South, with a very long period, and the wind is light enough to keep it semi-clean. But it’s only for experts. If you’re a beginner, stay away. The second-best might be the 7th of September, Monday afternoon, with a 4 ft swell from the South at 14 seconds, and a light cross-shore wind. It’s marginal, but it’s the most consistent option for the average surfer.

Overall, it’s a frustrating 16 days. The first week is dead, and the second week is either too big, too windy, or both. Keep an eye on the forecasts, but don’t hold your breath.

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.
