The Lowdown
Right, gather ‘round, folks. Rusty here with a look at what’s on the menu for Suruga Bay.
It’s been a pretty quiet start to the period, to be honest. The bay’s been flat and messy for days. Don’t get too excited until we get past the first week. We’re looking at a big gap of nothing worthwhile until we get to the 19th of September, with only tiny, weak, cross-shore slop that isn’t worth paddling out for.
The first real pulse of life shows up on Saturday the 19th. We get a bit of a bump, but the wind is a cross-shore mess and the conditions are described as marginal. It’s not the one. The swell builds through the day with a combined energy of 866, but it’s still not clean.
Now, Sunday the 20th of September is where we finally get a standout. For the morning, the bay (Suruga Bay) turns it on. We’re looking at a solid 7ft swell out of the SSE, and crucially, the wind is light and cross-offshore, giving us *clean* lines. The period is a long 14 seconds, a proper groundswell, and the combined energy is pumping at 2392. This is excellent surf, but the size puts it firmly in the experienced surfer’s territory. The water temp is about 80°, which is pretty normal for this time of year. Crowds are sometimes an issue here, so you might have to share.
After that Sunday high, Monday the 21st sees the swell peak around 10ft from the south, but the wind is back to a lumpy cross-shore, making it a messy, tricky paddle. The energy is huge at 3595, but it’s not going to be pretty. Tuesday the 22nd gets blown out completely by a near-gale cross-onshore, pushing a massive 15ft swell. That’s a hard pass for surfing, but if you’re into kites, that setup might be your jam.
The swell drops off a cliff after that. From Wednesday the 23rd right through to the end of the month, it’s back to tiny, weak dribble with poor winds. There’s a slight tickle on the 27th and 28th of September with some 4ft to 7ft swell, but it’s plagued by lumpy cross-shore breezes. Not recommended.
So, to sum it up: hold out for the morning of Sunday the 20th. That’s your clean, powerful window. The rest is either too small, too windy, or just a complete mess.
Stay stoked, and I’ll see you in the water.
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.
