The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s on the menu for Suruga Bay over the next couple of weeks.
Straight up, it’s a tough start. The first recommendation we get is for Thursday morning, the 6th of August, but it’s a real struggle. We’ve got a solid 8ft swell from the SSE, with a period of 14 seconds, and a massive 2318 combined energy. That’s a lot of power. But the wind is a cross-onshore from the ENE at 12 mph, making it choppy and poor. The afternoon is even worse, with onshore winds. That pattern of messy, onshore wind sticks around for days. The weekend of the 9th and 10th sees the swell drop a touch, but it’s still cross-on, and the consistency is questionable. The best of this first week, and it’s not saying much, is the Sunday morning the 9th, with a 7ft SSW swell at 15 seconds and 1888 energy. The wind is lighter, but still cross-on. It’s marginal at best. The water temp is about average for the time of year, nothing special.
The whole first week is a write-off for a proper session. The wind just won’t play ball. The swell drops right off into the second week, with heights falling below 3ft after the 12th.
Now, here’s the one true standout. You have to wait, but it’s worth noting. On Thursday, the 20th of August, we finally get a break in the gloom. The afternoon session shows a glassy surface with the wind from the NNE at just 3 mph. The swell is a small 5ft, but it’s from the east with a short period of 8 seconds. The combined energy is 443. The report says "expect good surf conditions". That’s the one. It’s the only window of truly clean, glassy conditions in the entire 16-day forecast. It’s not a big swell, but it’ll be the most fun you’ll have.
Before that, on the morning of the 18th, there’s a hint of a cross-offshore wind and clean conditions, but the swell is only 2ft, so it’s barely worth paddling for.
So, to sum it up: the first week is a blown-out mess. The second week has a flat spell. But if you’re patient, that Thursday afternoon on the 20th of August is your best bet. It’s the only time the bay looks like it will deliver clean, rideable waves.
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.
