The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Suruga Bay over the next couple of weeks.
First up, the water temp is sitting at a nice 81°F, which is pretty much bang on average for this time of year – no surprises there, just comfortable tropical warmth.
Right now, we’re in a bit of a flat spell. The first surfable wave doesn't show up until Tuesday the 15th, and even then it’s ordinary – just 2ft from SSE. The wind’s glassy, which is nice, but the energy is weak (53). It’ll get you wet, but don’t expect much. We’ve got a stretch of poor surf and mostly cross-shore winds hanging around from Wednesday through to Friday, so honestly, the breakwater isn’t offering anything decent.
The first real glimmer comes on Saturday the 20th morning. The wind is clean with a light cross-off breeze, and we’ve got 3ft of SE swell. Still not pumping, but enough to be rideable for beginners. The energy is moderate (566), so it’ll have a bit more push than what we’ve seen.
Now, here’s where it gets interesting for the more experienced crew. The standout window kicks off on the morning of Sunday the 21st September. We’re looking at a solid 10ft of S swell, with a period of 13 seconds – that’s proper groundswell. The combined energy is strong (3295). The wind is a bit tricky, coming cross-shore from the NE at 9 mph, but the swell has size and power. However, at over 8ft, this is experts-only territory.
The next big one to circle is Sunday the 27th September. The morning session looks excellent – clean with a light cross-off breeze, and a meaty 8ft S swell rolling in with a 14-second period. The energy is very strong (2656). This is a proper groundswell and the conditions are set to be clean. The water will still be warm. This is likely the best morning of the whole outlook for experienced surfers who can handle the size.
Looking further out, Monday the 28th September morning has a massive 10ft SSW swell with a *very long* 16-second period and an enormous energy reading (5286). The wind is light, but the size is staggering. For a breakwater setup, that is going to be huge, powerful, and potentially unruly – definitely only for the brave and the skilled.
For a final pick: for the intermediate and advanced crew, lock in the morning of Sunday the 27th September. For the beginners, your best bet is the cleaner morning sessions around Saturday the 20th September when the swell is manageable.
Rusty, signing off.

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.
