The Lowdown
Alright, this is Rusty. Let’s break down what Suruga Bay is offering up.
The standout moment is right at the start. Sunday morning, August 9th, is looking like the best shot we’ve got. There’s a clean 3ft swell from the SSW with a 10-second period, and the wind is glassy out of the ESE at just 3 mph. The water is a warm 80°F, about average for the time of year. Combined wave energy is sitting at a moderate 440, so there’s some real push behind it. This is a great beginner-friendly window with clean, glassy conditions.
After that, it turns rough. From Sunday afternoon through the first week, it’s mostly onshore or cross-onshore winds, chop, and poor conditions. The swell hangs around 2ft to 3ft, but the wind just messes it up. The combined energy drops into the low hundreds and even below 100 at times.
The second week doesn’t offer much relief. There’s a flicker on Wednesday, August 19th, with a morning bump to 4ft from the east, a 9-second period, and a light cross-shore breeze. Combined energy climbs to 267. But it’s only marginal. There’s also a chance on Friday, August 21st, with a glassy morning and a small 2ft S swell, but again, it’s very ordinary.
If you’re picking one day, make it this Sunday, August 9th. The rest of the 16-day window is mostly a write-off with blown-out or weak surf. For a break that’s usually very consistent, this is a quiet stretch. But things can always shift.
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.
