The Lowdown
Alright, Rusty here with a look at what’s coming up for Suruga Bay.
To be honest, the next 16 days look like a bit of a struggle for decent waves. We’ve got a real mixed bag of conditions, with very few moments where everything lines up. The standout session is clearly going to be Wednesday morning, August 26th. We’ve got a clean 5ft swell rolling in from the S, with a long 11-second period pushing moderate wave energy (507). The wind is a light WSW cross-offshore, which should leave the surface glassy and clean. It’s a beginner-friendly break, so expect some company – it’s a spot that *sometimes* gets busy. Water temp is sitting at 81°, pretty much spot on average for this time of year.
After that, the options fade fast. Tuesday the 25th has some size with 6ft swell from the SSE, but the crosswind and marginal conditions mean it’s not going to be pretty. The wave energy is strong (1588) but it’s messy.
Wednesday afternoon sees the swell bump up to 6ft from the SSW, but a fresh 30 km/h cross-offshore wind keeps it clean. However, conditions are still marked as marginal, so it’s not a guarantee of quality.
From Thursday the 27th onwards, we hit a real dry spell. The swell drops below 3ft, the wind turns cross or onshore, and the pulse in the water weakens fast. By Friday the 29th, energy is down to just 95 and 36, with tiny, weak waves. This flat spell stretches out for days.
There is a faint flicker on Tuesday morning, September 1st, with a 4ft S swell and 12-second period (379 energy), but the wind is light cross-onshore, so it’s a marginal look at best. After that, it’s more of the same – small, messy, and uninspiring right through to September 9th. The wave periods get short and the energy stays low, with the biggest bump being a sloppy 4ft from the SW with a weak 6-second period on September 9th.
Bottom line: Wednesday morning, August 26th is the only real window for a clean surf in this 16-day outlook. After that, you’re looking at a long wait with very little on offer.

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.
