The Lowdown
Alright, this is Rusty, and I’ve got a look at the Cape Toi forecast. Let’s be straight with you – it’s a rough stretch for this reef break on the exposed coast. The overall pattern is a long, frustrating run of poor conditions, with only a couple of very brief windows that might get you a few waves.
We start off with a real mess. From Wednesday the 26th of August through to the start of September, it’s a write-off. The wind is mostly cross-onshore or onshore, and it’s strong. You’re looking at heavy, lumpy, and choppy surf, with waves around 0.7 ft to 7 ft, but the quality is just not there. The combined wave energy is weak to moderate at best, hitting 938 during the early part, but it’s all blown out. The water temperature is about average for the time of year, but that’s the only good news.
The only real standout in this whole outlook is a freak event on the 3rd of September. It’s still a week away, so keep that in mind, but it’s the closest thing to a proper session. The morning shows a solid 16 ft swell from the SE, with a long period of 11 seconds, giving the place a massive 5608 combined energy rating. That’s a lot of water moving. The wind is a moderate cross-shore, which is workable, but this swell is going to be huge. Cape Toi can handle it, but if you’re not an expert, stay well away. This is for advanced surfers only. The afternoon looks cleaner, but the wave data is missing, so it’s a gamble.
Before that, you get a tiny, glassy window on Sunday morning the 30th of August. Swell is a pathetic 2 ft from the east, with a period of 12 seconds and a combined energy of just 96. It’s not much, but the wind is glassy, and that’s a huge positive. You’ll be on a longboard, scratching for knee-high runners, but it’s the only clean surf you’ll see in the first week. The break is inconsistent at the best of times, so that window is a real lottery.
After the 3rd of September, it falls apart again. The wind swings back to strong cross-onshore, and the swell turns into a messy, blown-out mix of wind swell and leftover groundswell. The 7th of September brings another massive swell of 18 ft from the east, but it’s accompanied by a fresh cross-onshore wind, making it dangerous and unrideable. The combined energy of 8233 is intimidating, but it’s a total loss for paddle surfing.
So, to sum it up: Cape Toi has a long, lean forecast. The only real hope is the 3rd of September for the big-swell crew, or the 30th of August for the desperate and the longboarders. Everything else is either too small, too blown out, or too big with bad wind. It’s a tough outlook.
Stay safe, keep an eye on that date for the 3rd of September, and don’t get your hopes up too high.

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.
