The Lowdown

Alright, surfers, Rusty here. Let’s get into it.

First up, I’ve gotta be straight with you – the next few days are a write-off. We’re looking at a real slow start, with nothing but tiny, wind-affected dribble for the first three days. Tuesday the 18th through Thursday the 20th, you’re better off doing something else. The swell’s barely there, and the wind is just junk.

Then, Friday the 21st morning, we get a little glimmer. The wind goes glassy at Suruga Bay, and we see a little bump of 2 ft from the south. The combined energy is weak (119), so it’s not going to be pumping, but for a beginner-friendly spot, that glassy surface is a major positive. It’s surfable, but very ordinary.

The real story starts to unfold from Monday the 24th. A serious groundswell is building. Monday morning we see 3 ft from the SE with a period of 16 seconds, and the energy is ramping up (369). That’s a long-period swell, which means it’s got shape and power, and it’s going to wrap in nicely. The afternoon sees that energy jump to 682, and the swell size stays around 3 ft. The winds are a bit messy, but this is the start of something.

Now, the standout. Tuesday, August 25th, is the day to circle. The morning session at Suruga Bay is looking clean with a light breeze from the east. The swell hits 6 ft from the SSE, riding that 16-second groundswell. The combined energy is a solid 1712, which means moderate, punchy waves. The water temp is 81°, which is about normal for this time of year (anomaly of -1°). This is a good size for most surfers, not too big, but with that long period, it’ll have proper push. The wind is light cross-onshore, but it’s manageable.

For the experts out there, keep an eye on Wednesday, August 26th, and Thursday, August 27th. The swell gets huge. Wednesday morning, we’re looking at 8 ft from the SSE, and the energy is 3162. By Thursday morning, it’s a solid 12 ft from the south with a massive energy reading of 6299. The wind is cross-shore, and the forecast is saying it’s just too big for this break. This is for the brave, the experienced, or the kamikaze only. The long period (16 seconds) will make it lineup, but it’s going to be a beast.

By Sunday, August 30th, the swell settles back to 8 ft, and then we get another beauty. Monday, August 31st, morning session is the best on offer for the second week. The wind is glassy, waves are 7 ft from the south with a 13-second period, and the energy is 1760. The conditions are excellent for experienced surfers. This is a big, clean, powerful day.

As we roll into September, the swell drops back to 4 ft to 6 ft, with mostly cross-shore winds. A long period from the ESE on the 1st (15 seconds) will still offer some fun lines, but it won’t match the quality of the 25th or the 31st.

So, to wrap it up: the first week is a dud until the 21st, but that’s just a teaser. The real standouts are Tuesday, August 25th morning for the first big, clean push, and Monday, August 31st morning for a glassy, powerful session. Get out there and earn it.

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.
