The Lowdown
Alright, let me take a look at what we’ve got for the next couple of weeks. Honestly, opening up the charts, my heart sank a little. There’s a real slow start here. For the first few days, from now through Friday the 31st of July and into Saturday the 1st of August, we’re looking at tiny, weak waves. We’re talking about knee-high slop at best, with a combined energy barely registering (41-30), and a short period swell that’s just not holding any juice. The wind is all over the place, but it’s not making it any better. It’s a flat spell, plain and simple. You’re better off waiting at home.
But then, hold onto your board, because Sunday morning, the 2nd of August, that’s when things start to wake up. The swell picks up out of the ESE, and while it’s still small, pushing 2 ft, the period jumps to a very long 16 seconds. That’s proper groundswell energy. The combined energy leaps to 246 (moderate), and we’ve got a light offshore breeze from the NW blowing clean. It’s not going to be huge, but it’ll be lined up and glassy. That’s a real nice session for the early crew.
Now, the real stand-out, the one you’ve been waiting for, is Cape Toi. This is a reef break, and it’s tricky—it’s inconsistent, and it only works when the conditions are just right. But when it lines up, it’s magic. The best window is looking like Sunday morning, the 2nd of August. We’ve got that clean 2 ft, 16-second ESE groundswell, with a light offshore. That’s a recipe for some smooth, lined-up waves that will hold up nicely on the reef. The crowd profile says “sometimes” here, so you might have a few others out, but it’s a big enough spot. That’s your pick of the whole forecast.
The surf builds through the next week, but so does the wind. By Monday the 3rd and Tuesday the 4th, the swell is pushing 5 ft to 8 ft, with that long period, but the wind turns cross-shore and starts to get a bit messy. The energy is strong (1394-6160), but the quality drops. It’s not going to be clean.
Then things get wild. From Wednesday the 5th of August through the weekend, the swell goes absolutely nuclear. We’re talking 16 ft to 34 ft of ESE groundswell, with very long periods around 18-19 seconds. The combined energy is enormous (16211-63652). But before you get too excited, this is way too big for Cape Toi. The reef will be a washing machine. The wind is a strong cross-shore, and the data says it’s “too big for this break.” Unless you’re a big-wave tow-in crew, you’re staying on the beach. For a regular paddle surfer, that’s a no-go zone. It’s more of a kite-surfing spectacle than a surf session.
The rest of the second week, from the 8th of August onwards, the swell drops back down to 4 ft to 8 ft, but the wind stays onshore from the east, making it choppy and blown out. The energy is still there (1410-615), but the quality is poor. There are a few mornings, like the 14th of August, with a light cross-offshore breeze, but the swell is short and weak. It’s a frustrating end to the forecast.
So, bottom line: Sunday morning, the 2nd of August, at Cape Toi. That’s your moment. Don’t sleep on it.

Information about the Cape Toi Surf forecast
The above surf forecast table for Cape Toi provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cape Toi can be found by selecting the local surf guide option on the grey menu. Our Cape Toi 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 (Cape Toi) 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 Cape Toi 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.
Cape Toi is 15 km (9 miles) from Kushima. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Kushima. Kushima has rooms for a wide range of budgets as well as car hire and transport links.
