The Lowdown

Alright, this is Rusty. Let's have a look at what we’ve got for the shores here over the next couple of weeks.

Right off the bat, I gotta be straight with you – the first week looks pretty grim. From today, Thursday the 13th, right through until the morning of Wednesday the 19th, the surf is going to be a total write-off. We’re talking tiny, weak swells with cross-shore and onshore winds messing up anything that tries to form. You’ll be sitting there watching a lake for days. The good news is, things shift towards the end of the window, but you’re gonna have to be patient.

We start to see a little pulse of life on the morning of Thursday the 20th at Suruga Bay. The swell is a weak little 3 ft from the S, and the period is only 8 seconds, so it's a windswell, not a groundswell. The combined wave energy is a very modest 122 (weak to moderate). What makes this a tiny glimmer of hope is the glassy conditions—that “slight air” with the wind variable – so the surface should be clean, even if the waves themselves are weak. The water temp is a warm 81°, which feels normal for this time of year. It’s a spot for beginners anyway, given the low swell.

Then there’s a real stand-out on the horizon, but it’s way out there. Come Sunday, the 23rd of August, and into Monday the 24th, a serious groundswell is forecast to push in. The morning of the 24th shows 5 ft of swell from the SSE with a period of 15 seconds. That’s a proper long-period groundswell. The combined energy (1238) is strong. The wind is light and cross-onshore from the ENE, which is okay but not perfect. By the afternoon, it jumps to 6 ft from the SSE with a 16-second period, and the energy is very strong (1703). That’s big for this break. However, that period is so long it might make the waves a bit fat and shut down on a beach break setup. It points towards the optimum SE direction for Suruga Bay, which is a good sign. Because the swell is over 5 ft but under 8 ft, it's getting into intermediate territory, and you might want to leave the beginner boards at home. Given it’s two weeks out, treat this as a promising possibility, not a guarantee. Crowds are sometimes an issue here, so there might be a few of us out there if it fires.

After that pulse, it fades back down pretty fast into the end of the month. The morning of Tuesday the 25th still has a solid 6 ft from the SE with a 15-second period (energy at 1268). The wind is light and onshore from the ESE, which will keep the surface a bit bumpy. It's still that same long-period groundswell, so expect those long lulls between sets, but the paddling out should be easier.

So, to sum it up: the first week is a dead loss. The second week has two windows to look at. The glassy morning of the 20th might give you a fun, weak wave if you just need to get wet. Your main target, the one that could be something special, is the long-period groundswell arriving around the 24th and 25th. Keep your fingers crossed and check back closer to the time.

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.
