The Lowdown
G’day, Rusty here. I’ll be straight with you – the next week and a bit is a write-off for any decent surf. We’re staring down a long, flat spell with nothing worth paddling out for from now until around the middle of next week. Don’t bother checking the beach.
Things finally start looking up on Friday the 18th of September. That afternoon, Suruga Bay picks up a clean pulse of swell. We’re talking a 2ft wave from the SSE with a very long 16-second period – proper groundswell energy coming through. The wind goes light and cross-offshore, keeping the surface clean. The combined energy sits at 294 (moderate). It’s not huge, but after so many flat days, this is the first real sign of life. The water temp is a warm 81°, right on average for this time of year, so no surprises there.
Now, the real standout window is the weekend. Saturday the 19th of September sees the swell building fast. By the afternoon, we’ve got 7ft of SSE swell with a 16-second period, pumping out a massive 4128 combined energy (strong). The wind is cross-shore from the NE at 12 mph though, so it’ll have a bit of chop on it – not perfect, but there’s plenty of power. Sunday the 20th of September is the pick of the bunch for experienced surfers. The afternoon session brings 8ft of S swell, 15-second period, and the wind switches to a clean cross-offshore from the NNE at 9 mph. That’s 2562 combined energy (strong) and clean conditions. This one’s for the crew who know what they’re doing – anything over 7ft and this break can get intense.
A heads up: by Monday the 21st and Tuesday the 22nd, the swell goes big – over 10ft – and the wind turns gnarly, especially Tuesday when we see a fresh 22 mph cross-shore and onshore breeze. That’s expert-only territory, and honestly, conditions get messy. Wednesday the 23rd of September has a massive 21ft swell predicted, but the data says it’s too big for this spot – steer well clear, that’s more of a big-wave event for a different coast.
The 24th of September (Thursday) drops back down to a more manageable 6ft SSW swell with an 11-second period and light cross-offshore wind, giving us clean surf and 954 combined energy (moderate). A good option for those who missed the weekend.
So, the best on offer is Sunday afternoon the 20th of September: 8ft S swell, 15-second period, clean cross-offshore wind. That’s your standout. As a runner-up, Friday afternoon the 18th is a nice, clean warm-up. Crowds are listed as “sometimes” at Suruga Bay, so you might have some company, but it shouldn’t be a zoo.
Stay safe, read the conditions, and don’t even bother with the beach until next Friday.
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.
