The Lowdown
Alright folks, Rusty here with the long-range outlook for Suruga Bay. Let’s get into it.
The next week and a half is mostly a waiting game. We’ve got a long gap of small, messy conditions before things finally crank up. The first real window isn’t until around Thursday the 3rd of September, when a pulse of new southerly swell starts to fill in. But even that is just a teaser.
Saturday morning the 29th is glassy and tiny, with a weak 2ft SSW swell. It’s surfable for a beginner, but honestly, it’s pretty ordinary. The energy is weak (53) and the 6-second period means it’s just wind chop. The water is a warm 82°, which is about average for this time of year.
The whole first half of the week – through to Wednesday the 2nd – is basically a write-off. Tiny waves, onshore winds, and that combined energy barely cracks 100. We’re talking knee-high slop at best. There’s a five-day stretch of almost nothing worth paddling for.
Thursday the 3rd brings a pulse: a 4ft south swell in the morning, building to 5ft by the afternoon. The period jumps to 10-12 seconds, and the combined energy gets into moderate territory (334 to 623). But it’s cross-on shore, so it’ll be lumpy.
The standout – and I mean the real highlight – is Friday the 4th. This is the one. Overnight the wind goes glassy, and that southerly swell pumps up to a solid 8ft in the morning, hitting 10ft by the afternoon with a clean 10-second period. The combined energy skyrockets (1169 to 2863). For experienced surfers, this is excellent. You’ll want to be on it early before the rain sets in. This is an experts-only session – that 10ft is legit and not for the faint of heart. The swell is coming from the SSW, which matches the optimum direction for Suruga Bay perfectly.
After that peak, Saturday the 5th gets hammered by a fresh 30 km/h cross-shore wind. The waves drop back to 4ft and it’s all chop. Sunday the 6th is even smaller and still windy.
Then, Monday the 7th offers another window. The morning is glassy with a 6ft south swell and a very long 12-second period. The energy jumps back up (945). This will have some real push and shape. The afternoon gets a little messy with cross-on wind as it builds to 8ft, but that morning session should be great.
Things get wild and too big for this break from Tuesday the 8th through the 9th, with 15ft to 12ft southerly swell. That’s way too much for Suruga Bay, and the finder notes say as much.
After that, it drops back into mediocrity. A new SSE groundswell shows up on Sunday the 13th with an 8ft swell and a 14-second period, but it’s cross-on and the forecast is marginal. It’s too far out to get excited about, but worth keeping an eye on.
So, bottom line: This is a tale of one perfect day. Lock in Friday the 4th of September – that morning glassy 8ft SSW swell is your best chance for a proper session. Monday the 7th morning is the backup. Everything else is either too small, too windy, or way too big.
Rusty, signing off.

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.
