The Lowdown
Alright, let’s get into it. Suruga Bay is a breakwater spot that’s very consistent and beginner-friendly, usually holding up best with a SE swell direction. Thing is, the next week and a half is pretty much a write-off for any decent surf. We’ve got a solid run of poor conditions from the 31st of August all the way through to the 7th of September. Swell heights are tiny, mostly between 1.0ft and 3ft, with short periods and weak energy (22 to 204). The winds are never working in our favour either – cross, cross-on, or onshore pretty much the whole time. It’s a flat, bumpy stretch with no real hope.
There’s a gap of almost a week before we see anything with potential. Things start to look up on the afternoon of Monday the 7th of September. We’ve got a 3ft swell from the S, with a 12-second period, and a light west wind going cross-offshore. The combined energy jumps to 428 (moderate). The report says, “expect good surf conditions,” so that’s the first real window. It’s not huge, but it’s clean.
Tuesday the 8th of September keeps things interesting. The morning is a bit marginal with a 4ft S swell and a light cross-on breeze, but the afternoon looks magic. The wind drops to glassy, and we’ve got a 4ft S swell with a 9-second period and 232 energy. It’s clean, small, and perfect for the beginners this spot is known for. The water temp is about average for the time of year, nothing unusual.
Now, the standout. Tuesday the 15th of September morning is a beast. A massive 15ft groundswell from the SSE, 13-second period, and a moderate NE cross-shore breeze. The energy reading is 7246, which is very strong. But here’s the thing – the guidance says it’s predicted to be too big for this break. The score is high, but only for experts, and even then, it’s going to be a wild, powerful beast. If you’re not a seasoned charger, stay well clear.
The best overall bet is that glassy Tuesday afternoon session. Clean, small, fun, and no crowds mentioned. For the brave, Monday the 7th afternoon is also a solid option.

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.
