The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Suruga Bay.
Right now, it’s a bit of a slow start. The surf is tiny and the energy is weak. Wednesday the 19th and Thursday the 20th are basically flat with ankle-biters, poor conditions, and the swell energy is next to nothing. We’ve got a bit of a wait ahead. Friday the 21st and Saturday the 22nd see a small bump, but it’s still small and messy with cross-onshore winds, so nothing to get excited about. Sunday morning the 23rd has a brief moment of glassy conditions with a slight increase to 2ft, but it’s still ordinary.
The real change starts rolling in on Monday the 24th. Monday morning looks clean with glassy conditions, a 2ft SE swell, and a long period of 16 seconds. The combined energy jumps to 402 (moderate energy). That’s a promising start, but the real standout is Wednesday the 26th. Wednesday afternoon we’ve got a solid 10ft S swell with a 15-second period, combined energy hitting 3848 (very strong), and crucially, a light cross-offshore wind from the NE keeping things clean. That’s excellent surf for experienced surfers only – this is too big for beginners.
Thursday the 27th and Friday the 28th are a mixed bag with heavy rain and strong winds, though Friday afternoon sees a massive 12ft S swell with 11-second period and energy of 4774, but it’s too big for this break and the wind is cross-onshore. The rest of the period into early September has marginal conditions with a mix of average swells and onshore winds, so nothing to get too excited about. The water temperature is sitting at 80°F, which is a bit colder than normal for this time of year.
Best bet: mark your calendar for Wednesday the 26th afternoon. The combination of size, period, and clean winds makes it the best of the run.
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.
