The Lowdown
Alright, Rusty here. Let's get into it.
The next couple of days are a write-off for anything decent at Suruga Bay. We've got tiny, weak swell and cross or onshore winds messing things up. Saturday morning the 22nd might look surfable on paper, but trust me, it's ordinary – barely a push and the wind isn't helping. We have to wait it out through Sunday the 23rd as well.
Monday morning the 24th is where things finally turn. The wind goes glassy, and a new long-period groundswell pushes in from the SSE, around 4ft. The period is a very long 18 seconds, and the combined wave energy is a solid 856, so there's real power behind it. This long period stuff can be a bit straight at a beach setup, but for a breakwater like Suruga Bay, it should wrap in nicely. That’s your standout session.
We get a bit cleaner on Tuesday morning the 25th, but the swell has built to 8ft from the S with a 15-second period. That's a lot of water moving around. Combined energy is well into four digits at 2612. That's big and powerful – experts only territory, and only if the tide and wind line up perfectly. The cross-shore wind will make it tricky. Not a day for the faint-hearted.
Wednesday the 26th is another good shout. The swell drops to a more manageable 6ft from the S, and we get glassy conditions in the morning. The period is still a solid 13 seconds. It's got some grunt (1203 energy), but the conditions are set to be excellent for experienced surfers. The afternoon looks clean too with a light cross-offshore breeze.
After that, the swell fades out. We drift into smaller, more inconsistent waves for the rest of the week and into the start of September. There are a few knee-high mornings with clean conditions, but nothing worth getting excited about.
Looking ahead to the first weekend of September, the 5th and 6th, we see a bit of a pulse. Saturday morning the 5th is clean with light winds and a small 3ft SSW swell. Then by Sunday morning the 6th, we're back up to 5ft from the S with a 13-second period and a combined energy of 1149. The wind is light cross-shore, so it's worth keeping an eye on for a potentially fun, punchy session, but it's still a week and a half out, so don't set your watch by 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.
