The Lowdown
Alright, Rusty here. Let's talk about what's shaping up for Suruga Bay.
We're in a quiet patch right now, no doubt about it. The first week or so is pretty flat or just messy. From Saturday the 12th right through the middle of the week, there's barely anything to get excited about. Tiny waves and nothing clean enough to recommend. You're basically looking at a gap of about six days with very little worth paddling out for.
Things start to get a bit more interesting towards the end. On Friday the 18th, a big groundswell arrives with a very long 17-second period, but it's blown out by a fresh cross-onshore wind. That combined swell energy is strong, but the wind kills it. The break is a bit exposed here, and the wind is just tearing it up.
Now, the standout window begins on Wednesday the 23rd. The swell is massive, hitting 15 ft from the SSW with a 13-second period. It's too big for most, but for the experts, the wind goes clean offshore from the west. The energy is insane. That afternoon is for the big-wave crew only.
Looking further ahead, Thursday the 24th morning offers a bit more sanity. Clean, glassy conditions with a 5 ft SE groundswell (16-second period). That combined swell energy is still strong. The wind is dead calm, so it’ll be some of the cleanest, most lined-up waves of the entire period. It's a solid option for experienced surfers.
Then on Friday the 25th, another glassy morning with a bigger 7 ft SSE swell, again with a very long 16-second period. Wind is nil, making for pristine conditions, but that swell size pushes it into expert territory. The energy is very strong.
There's potential on Saturday the 26th, but the swell from the SSE is huge at 12 ft with a 17-second period. The combined energy is extreme. It's just too big for Suruga Bay to be a friendly wave for the majority, even with moderate cross-shore wind.
Overall, the best bet for clean surf that most advanced surfers can handle is the morning of the 24th. The glassy wind and solid groundswell are a rare combo here. For the absolute charger, the 23rd afternoon is the one, but that's a whole different level.
Stay patient, wait for that glass-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.
