The Lowdown
Right then mate, Rusty here, and let's have a proper look at what's cookin' for the Cape. I gotta be straight with ya, the next week and a half or so is lookin' pretty flat and ordinary. There's a real dry spell from now until around the 24th of August, a good ten days where you're honestly better off doin' something else. The swell's tiny, the wind's mostly cross or cross-onshore, and it's just choppy, messy, and not worth paddling out for. It's a bleak run.
Now, things get a bit more interestin' towards the back end of the outlook. The real standout here is Tuesday the 25th of August at Cape Toi. This is the one to circle on the calendar. Swell jumps to 4 ft from the ESE, but the magic is in the period – a very long 14 seconds. That's proper groundswell energy. The combined energy is strong at 690. And the wind? Glassy. Dead flat. The overhead conditions are going to be pristine. For a break that's on the reef and exposed, this incoming groundswell with clean, glassy conditions is a recipe for some memorable waves. It won't be one for the beginners though, that reef demands respect. The other morning on the 26th of August pushes up to 5.6 ft from the E with glassy winds again, but that's big, powerful stuff. That's expert territory, mate. The energy is very strong at 1078, so you'll feel the ocean breathing hard.
For the rest of the second week, there are a couple of smaller windows. The 24th morning has a clean 2 ft swell from the ESE with a very long 16-second period and offshore WNW wind, but it's small. The 27th of August cleans up again with glassy conditions and 4.3 ft from the East, offering some decent, clean if not standout, waves. The water temp is a balmy 82.8° , which is about average for this time of year, so a spring suit or just a rash vest will do ya fine for that glassy Tuesday.
Keep your eyes on that Tuesday the 25th. That's the one that's got the potential to be a session you'll talk about. The long-range call looks promising, but we know how that goes. For now, don't bother with the early stuff – it's a write-off.

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.
