The Lowdown
Alright, let’s talk about Suruga Bay. I’ve been looking at the charts and, honestly, for the next ten days or so, it’s a bit of a tough watch. The swell is tiny and the wind just won’t play ball. We’ve got a long stretch here from the 17th of July all the way through to the 26th where the surf is just not worth paddling out for. It’s flat, it’s messy, and the energy is weak. You’re looking at combined swell energy as low as 15 (weak) up to maybe 299 (moderate) on the 26th, but even then the conditions are poor. It’s a real dry spell.
Then, things start to get interesting around the 27th of July. A big, long-period groundswell from the south rolls in with a period of 14 seconds and combined energy hitting 2727 (strong). That’s a proper swell. The catch? It’s pushing 8ft to 8ft. That’s expert territory, and the wind is cross-shore, which will leave it a bit lumpy. The break is a breakwater setup, and with that long period, it might be a bit too straight for a beach break, but here it could hold some lines. Expect crowds, as it’s sometimes crowded.
The water temp is sitting at 78° which is about normal for this time of year, so no wetsuit worries.
The standout here is Monday the 27th of July, early. You’ve got a solid 8ft S swell with a 14-second period and light cross-shore wind. It’s big, it’s powerful, and the energy is huge (2727). This is not for the faint-hearted, but if you’re an expert, that’s your window. Tuesday the 28th is similar in size, but the wind gets worse. Wednesday the 29th holds the size but the wind is onshore.
After that, it drops off again. The 31st of July has another 10ft pulse, but it’s short period (9 seconds) and onshore wind, so it’s a mess. The first of August sees a drop back to small, poor surf.
So, the one true standout is Monday the 27th of July morning. It’s big, powerful, and your best chance for a real wave. Get on it if you’ve got the skill.

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.
