The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' in Suruga Bay.
Right off the bat, I gotta be straight with you – the next week and a half is a tough one. We've got a stubborn stretch of small, poor-quality surf that's gonna leave us waiting. From Wednesday the 9th all the way through to Monday the 21st, it's a real desert. The waves are tiny, often under 3 ft, and the wind is mostly cross or cross-on, which is just trashing what little shape there is. There's a brief moment on the morning of Tuesday the 15th where the wind goes a little offshore and the water cleans up, but the swell is only 2 ft, so it's knee-high slop at best. Honestly, not worth paddling out for any of it.
The wait is long, but it looks like it might be worth it. The real spark in this forecast comes right at the end. On Tuesday, September 22nd, we start to see a pulse of energy. The swell direction swings around to the south with a very long period of 16 seconds (243), which is a classic groundswell signal. But it's still small, so that's more of a teaser.
The standout is undeniably Wednesday, September 23rd and Thursday, September 24th. A proper south swell fills in. On Wednesday morning, we're looking at 7 ft at 16 seconds, and by Thursday the 24th it's pushing 10 ft at 17 seconds. That's a deep, powerful, long-period groundswell – the kind that carries a ton of energy (5480 combined). The wind is cross-shore from the NE, but it's a moderate to gentle breeze, which should keep the surface reasonably clean. This is a big swell, over 8 ft, so this is for experienced surfers only. The sets will be long and powerful, with plenty of time between them to get back out. Being a breakwater setup, that long period should wrap in nicely, giving some proper, hollow lines. The water temp is about average for this time of year, so you'll be fine in a spring suit or shorty.
This is the one to circle on the calendar. It's a long way out, so keep an eye on the charts, but if this holds, Suruga Bay is going to have some serious muscle.
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.
