The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at the Cape Toi forecast for the next couple of weeks.
Right off the bat, Tuesday morning, August 11, is the only real moment for a wave in the first week. Cape Toi is a reef setup, exposed to the east, and it loves that NE groundswell. We’ve got a clean 5 ft from the east, with a 12-second period that gives the waves some proper push. The water’s sitting at 84°, right on the money for this time of year. The combined swell energy is a solid 555 (moderate wave energy), and the wind is glassy, light from the NNW. The waves will have that glazed, clean face you dream about. If you’re an intermediate surfer, this is the standout session. The spot is inconsistent, but when it fires like this, it’s special. Crowds can show up sometimes, so don’t sleep in.
From Tuesday afternoon through the rest of the week, it’s a write-off. The wind swings onshore and cross-on, the energy drops, and the waves get short and messy. Thursday and Friday are particularly weak, with energy in the 80 to 152 range. Not worth paddling out.
The weekend of August 16 and 17 isn’t much better. The swell sticks around 3 ft to 5 ft, but the wind is cross-on or onshore from the east and southeast. The wave faces are chopped and messy. No real clean windows.
Then there’s a long gap of nothing really surfable until Tuesday morning, August 25. That’s over a week of waiting. But when it comes, it comes big. Tuesday morning shows a 7 ft swell from the southeast with a 13-second period. The combined energy jumps to 1803 (strong wave energy). That’s a solid, powerful groundswell heading into the reef. Wind is light from the south, cross-on, so it won’t be glassy, but there’ll be raw power. The afternoon pushes it to 10 ft with a 14-second period and huge energy of 2848. That’s expert territory – only for the experienced crew. The wind goes onshore, so expect some chop on the bigger sets.
Before that, Saturday morning, August 22, offers a brief tease: a glassy, calm morning with a weak 3 ft southeast swell, energy of 158. Surfable but ordinary. Not a standout.
So, the honest call: Tuesday morning, August 11 is the cleanest, most fun wave on offer. If you’ve got the skill and nerve, the huge swell on August 25 will be a memorable, heavy session for experts.
Signing off,
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.
