The Lowdown
Alright, Rusty here again. Let’s go over Cape Toi in feet and miles per hour – same story, just different numbers.
There’s a big dry spell at the start with pretty much nothing worth talking about for nearly two weeks. From Thursday the 13th of August through the middle of the following week, it’s all tiny junk, weak energy, or blown out. The combined swell energy is low to moderate, around 80 to 400, but nothing lines up. Water’s 83°F, right around normal for this time of year.
The one bright spot is Sunday the 23rd of August. Swell will build from the ESE at 5 to 6 feet, with a period of 15 seconds – that’s a proper long-period groundswell. Combined energy hits 1330, so there’s some serious weight behind it. Wind is moderate cross-shore from the ENE at 16 mph, putting some chop on the face. For a reef that likes a NE swell, this ESE angle isn’t perfect, but the power and length will still produce some good ones. The break is inconsistent and sometimes crowded, so you’ll have to be patient and maybe share waves. Not for beginners.
Monday the 24th of August pushes even bigger – 8 feet to just over 8 feet from the ESE, with periods of 14-15 seconds. Combined energy goes huge at 2381 to 2521. But the wind picks up to a fresh to strong cross-shore from the NE and ENE at 22-25 mph, making it lumpy and cross-chop city. That’s expert-only territory.
After that, Tuesday through Thursday turns nasty – near gale winds onshore, blowing everything out. By Friday the 28th, it’s tiny and weak again.
If you kite, those big windy days from the 24th might be your jam. For surf, Sunday the 23rd is your best shot – promising, but it’s a long way out, so stay flexible.
Rusty.

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.
