The Lowdown
Alright, Rusty here. Let’s have a look at what Suruga Bay’s got cookin’ for the next couple weeks. Gotta be honest with ya, this one starts off slow… real slow. We’re lookin’ at a pretty flat, wind-chopped scene for the first stretch, and it’s a bit of a heartbreaker because this spot can be magic. Water temp’s sittin’ around 80°, which is bang on average for this time of year, so the wettie choice is easy.
We’ve got a solid gap of nearly no surf worth paddlin’ out for from now, through to about Friday the 19th of September. It’s mostly small, cross-shore junk in the 1ft to 2ft range with weak energy (as low as 23), and a fair bit of rain and lumpy wind. Nothin’ to write home about.
Come Saturday the 19th, things start to wake up. A pulse of swell pushes in at 4ft from the SE with a moderate 14-second period. Combined energy jumps to 658, so you can feel some push. But that NE wind is still blowin’ 16 mph, cross-shore, so it’s gonna be a bit lumpy. This is more of a “keep an eye on it” situation.
Through Sunday the 20th into Monday the 21st, the swell builds proper. We’re lookin’ at 6ft to 8ft from the SSE and S, period holding at 13 to 14 seconds, and energy goin’ from 2036 right up to 3117. That’s solid, moderate-to-strong energy. But again, that NE wind is a menace, 16 to 19 mph cross-shore. The wave comment calls it marginal. For a beginner spot, this is gettin’ big and messy. This is not the day for a learner.
Now, here’s the standout… and it’s a big one, but you gotta know what you’re doin’. On Tuesday the 22nd of September, the forecast throws a monster at Suruga Bay. We’re talkin’ a 23ft to 28ft swell from the S, with a long, powerful 15 to 16-second period. Energy readings are insane: 31,557 to 35,095. That is very strong energy. This is expert-only territory. The wind is still cross-shore from the ENE at 19 to 25 mph, so it’s not gonna be glassy. The report says the swell is just too big for this break. If you’re a seasoned charger and you know this place handles big water, maybe you paddle out, but for 99% of us, this is a watch-from-the-cliff day. It’s also more than a week away, so keep tabs.
After that spitfire, things drop off quick. Wednesday the 23rd sees clean conditions from a WSW wind, but the swell crashes to 4ft to 5ft with short period (8 to 9 seconds) and low energy (245 to 421). It’s clean, but weak. Not much grunt.
Then we hit another dry spell. From Thursday the 24th right through Saturday the 27th, it’s back to small, weak junk. Mostly 2ft to 4ft, short period, energy under 150. Wind is light but variable, mostly cross or cross-on. Nothin’ to get excited about.
But hold on… Sunday the 27th of September morning has a little glimmer. A glassy, windless morning with small 4ft swell from the S at 13 seconds. Energy is 464, so it’s moderate. The report says “expect good surf conditions.” That’s a nice, clean, small-wave window for the longboard or a fun fish. Afternoon wind swings onshore, so make it a dawny.
Finally, the real gem of the outlook is Tuesday the 29th of September. Mark it. Morning session: glassy as a lake, calm wind, with a solid 6ft swell from the SSW, a nice 14-second period, and combined energy of 1,577. The report says “excellent surf conditions for experienced surfers.” That’s the pick of the period. Clean, powerful, and well-shaped. This is a dawn patrol special for the crew who know what they’re doin’. Wednesday the 30th holds similar size (7ft to 7ft, SSW, 15-second period) with clean conditions and a light offshore wind from the north in the afternoon. Also excellent.
So to sum it up: the first week is a write-off. The standout is the morning of Tuesday the 29th of September, with the morning of Wednesday the 30th as a close second. If you’re an expert and hungry, the 22nd is there, but it’s a beast. Keep the 27th morning on the radar for a small, clean session.
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.
