The Lowdown
G’day, Rusty here. Let’s have a look at what’s coming down the pipe for Cape Toi reef. This is a pretty wild forecast, so strap in. The water is sitting at 85°F, which is about 2°F warmer than usual for this time of year – definitely feeling that tropical bath.
Right off the bat, Sunday morning the 2nd of August is your first real option. We’ve got a clean 2ft swell coming out of the ESE with a very long 16-second period pushing some moderate wave energy (320). The wind is light and offshore from the NW, so it’ll be glassy and lined up. This is a rare little gem before the chaos hits. Expect some good, clean reef waves. It’ll be inconsistent, so you’ll be waiting between sets, and crowds are possible.
After Sunday midday, the wheels start to come off. The wind swings onshore, and we get into a messy, choppy pattern that lasts right through Monday, Tuesday, and most of the following week. The swell builds, but the wind is all cross or cross-onshore, meaning bumpy, blown-out conditions. Not worth paddling out for a proper surf.
Now, the standout event is on Wednesday the 5th of August, and this one’s for experts only. We’re looking at a massive 16ft to 20ft swell from the E with an 18-second period pumping some seriously heavy energy (15,322 to 21,813). The wind is cross-shore from the NE, so it won’t be glassy, but the sheer size and power will make for some heavy, critical reef waves at Cape Toi. This is big, raw ocean energy. If you aren’t a seasoned charger, stay on the sand. The combination of huge swell and cross-wind means it’ll be a battle, but the wave quality for the brave will be there.
Thursday the 6th of August pushes things even further. Swell hits 26ft to 28ft, with periods around 17-18 seconds and energy readings through the roof (40,269 to 48,191). Again, near gale force winds blowing cross-shore. This is a wild, dangerous setup. Only the most experienced local chargers should even think about it.
After that, from Friday the 7th through to the second week, it’s a write-off. The wind stays strong and onshore, the swell gets chopped up, and conditions are poor. There’s a brief window around Wednesday the 12th of August where the wind drops a little and we get a 6ft swell with a longer 12-second period, but it’s still cross-shore and only marginal. The rest is just onshore junk.
So, to sum it up: Sunday morning the 2nd is your clean, fun-sized window for the everyday surfer. The 5th and 6th of August are for the big-wave crew only. Everything else is a wait-and-see.
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.
