The Lowdown

Alright crew, Rusty here. Let’s chew the fat on what Suruga Bay is serving up for the next couple of weeks.

First things first, it’s a dead start. The next few days are flat and ugly – small, weak slop and crappy wind. But don’t lose hope, there’s a proper pulse of energy lined up for the tail end of next week that’s got some teeth. You just gotta wait.

From Thursday the 20th through the weekend, it’s a total washout. We’re talking ankle-slapping 1ft to 2ft SSW junk with cross-shore breezes wrecking any hope of a wave. The combined energy is puny, barely hitting 30 to 103. Save your energy. There’s a fleeting chance on Sunday the 23rd morning with a light 3 mph wind, but it’s still just 2ft of garbage. Not worth wetting a wetsuit.

Now, Monday the 24th brings a shift – the swell jumps to 5ft from the SSE with a long 16-second period. That’s real groundswell energy, and the combined energy is strong, sitting between 1278 and 2059. However, the wind is still messy – cross-shore or cross-on – and the report tags it as marginal. If you’re aching for a paddle, it’s a maybe, but keep the expectations low.

Tuesday the 25th is the golden child, no debate. Early morning, everything clicks. The swell is a meaty 10ft from the S with that same long 16-second period, pumping out a massive 4979 combined energy. And the wind? Glassy. Dead calm, clean as a mirror. For experienced surfers, this is the session to mark on the calendar. The wind stays light into the afternoon, but the swell pushes to 12ft, which starts to get a bit overwhelming for this spot. Tuesday morning is the peak of the whole 16-day forecast. One heads-up: crowds are common at Suruga Bay, so expect to share the peak.

After that high point, Wednesday the 26th turns ugly fast. The swell holds at 10ft from the S, but the wind swings onshore from the NE and kicks up to 15-18 mph, bringing rain. The combined energy is still high (3538 – 3038) but the surface gets lumpy and messy. By Thursday the 27th, it’s a full-on blowout with 25-28 mph easterly winds and massive 13ft swell. That setup is more for kite surfers than paddle surfers – too much wind and chaos.

Friday the 28th offers a bit of relief with cleaner conditions as the wind swings offshore from the W, but the swell drops to 8ft and the period shortens to 9 seconds. It’s clean but not the quality of Tuesday morning. From Saturday the 29th onward, it’s a slow fade. The swell eases from 5ft down to a pathetic 2ft by the 4th of September, with persistent cross-shore and cross-onshore winds keeping things average. There’s a bit of long-period energy (12 seconds) in early September, but it’s small and messy. No more highlights.

Water temp is sitting around 80°F, which is a touch cooler than usual for this time of year – nothing wild, but you might notice it.

Bottom line: Do not waste your time until Tuesday the 25th. That morning is the real deal – big, clean groundswell with glassy conditions. After that, it’s all downhill. The second week is a write-off.

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.
