The Lowdown
Alright gang, Rusty here. Let’s break down the surf for Suruga Bay over the next couple of weeks.
First thing I gotta tell you, the first week is a bit of a grind. There’s some swell around, but the wind is a real pain in the neck. For the first ten days or so, it’s mostly onshore and cross-shore breezes ruining what could be alright waves. The water is sitting at 81°F with an anomaly of -0.7°F, so it’s just about normal for the season, nothing special.
The first real chance to get a clean one is on Sunday morning, the 16th of August. We’ve got a clean, glassy feel with a light cross-offshore breeze from the WSW. The waves are small, around 2ft from the SSW with a 10-second period, and a combined energy of 153 (moderate). It’s not massive, but the conditions will be the best we’ve seen in a while. It’s a beginner-friendly spot, so if you just want to stretch your arms, that’s your morning.
Then it goes quiet again until the 19th of August. Wednesday morning, the 19th, we have a clean bump of 3ft from the SW, but the period is a short 5 seconds, so it’ll be a bit weak and messy. The energy is only 111 (moderate). Still, it’s clean and the wind is light and offshore, so it’s worth a look if you’re keen.
The one to really get excited about is the 22nd of August. Saturday morning sees a bump in size to 4ft from the SSW, with a 10-second period and a combined energy of 250 (moderate). The wind is light from the ESE, so it’s a little onshore, but there’s some juice. Remember, this is a breakwater, so the angle is a bit off from the optimum SE direction, but the size is the best of the run.
But hold onto your hat, because the real deal is the 25th into the 26th of August. Tuesday morning the 25th has a clean, cross-offshore wind from the WSW and a groundswell from the S with a *very long* 15-second period. The swell is only 2ft, but the energy is a punchy 228 (moderate). That’s a sign of a bigger pulse coming. Then Wednesday morning the 26th, that pulse arrives: 5ft from the S, with a 13-second period and a combined energy of 997 (strong). That’s the biggest energy reading of the whole forecast. The wind is cross-shore from the SW, which isn’t perfect, but this is a proper groundswell. For a beginner break, 5ft is getting serious, and that long period will make it surge, so it’s for the experienced crew only. This is the one to watch, but it’s a long way out, so don’t book the day off yet.
For the rest of the run, it’s mostly small, messy, or onshore. The 23rd of August has a glassy morning, but the waves are tiny at 2ft.
So, my picks: For the cleanest, most user-friendly waves, hit Sunday morning the 16th of August. But for the real power and size, the best bet is the window around Wednesday the 26th of August – that’s when the ocean is going to show its teeth.
This is Rusty, signing off.

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.
