The Lowdown
Sunday, August 2nd – The swell is small, only 0.6m from the ESE with a long 16-second period, but the wind is a cross-onshore mess. Combined energy is weak (179). It’s a no-go. This carries into Monday the 3rd and Tuesday the 4th. The swell builds to 1.2m and then 1.8m, but it stays choppy and bumpy.
Wednesday, August 5th – The swell pumps up to 2.5m from the SE, and the energy jumps to moderate-strong (3296), but the wind is a fresh 30 km/h cross-shore. Lumpy, ugly surf. Thursday the 6th is the real kicker: we see a massive 4.0m SSE groundswell, with a very strong energy reading (9491), and the wind is cross-shore. This is big, powerful stuff, but at this break, for a beginner spot, it’s just too big, and the conditions are a mess. *Not* for the faint of heart.
The pattern of big, windy swell continues right through to Sunday, August 10th. The swell drops a touch to 2.0m from the SSW on Monday the 10th, but we’re still dealing with lumpy cross-chop. There’s a window on Tuesday, August 11th that might catch your eye. The swell is 1.7m from the SSW, and the wind finally eases to a light 10 km/h cross-shore. The energy is moderate (1373). The conditions improve, making it a marginal call, but compared to the rest of the week, it’s the first time you might consider a session. Wednesday the 12th morning also has that light cross-shore wind with a 1.3m swell, but it’s still a bit lumpy.
From Thursday, August 13th onwards, it all fades. The swell drops below 1m, and by the weekend of the 15th, we’re looking at tiny 0.5m leftovers with strong, messy winds. A stormy period with risk of thunderstorms kicks in around the 14th and 15th, making it a write-off.
So, the standout window is a very narrow one. If you’re itching, Tuesday morning, August 11th is your best bet. The swell is a solid 1.7m from the SSW, and with that light cross-shore breeze, it’ll be the cleanest we see for a while. It’s a spot that’s very consistent, but don’t expect perfection. The rest of the month looks grim until the energy returns.
Stay patient, mate.

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.
