The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Cape Toi. This is a reef setup that’s a bit of a speciality spot, and it’s exposed to the swell, but it’s inconsistent, so you have to pick your moments. We’ve got a long 16-day window ahead, but it’s a mixed bag. There’s a big gap of poor conditions at the start, and the only real standout appears later on.
The overall pattern is grim for the first week. We’re staring down the barrel of a solid, but messy, pulse of swell from the SE and ENE, but the wind is just horrible. It’s mostly cross or cross-onshore, with fresh to strong breezes. The water temp is sitting at 84°, which is about normal for the time of year. The combined wave energy is moderate to strong, with values like 1067 and 1558 early on, but it’s all wasted on choppy, lumpy conditions. It’s a write-off through Thursday, Friday, and the weekend, with heavy rain and thunderstorms adding to the misery. The swell is big – over 8 ft at times – so it’s expert-only anyway, but the wind is just trashing it.
Come Monday the 7th, things start to look a little more interesting. The wind finally goes cross-offshore from the NNE, but the surf is still huge – 12 ft from the NE with a period of 11 seconds. That’s a lot of energy (3112) and the setup is clean, but it’s for experts only, and the guidance says it’s marginal due to tide. It’s a big, powerful groundswell, so it’ll be walling up on the reef. Not a beginner’s day.
There’s a bit of a lull in the middle of the week, with smaller, cleaner swells, but nothing that really fires.
Here’s the one true standout. Thursday the 10th. The morning session is where it’s at. The wind drops to a whisper – just 3 mph from the NNE, cross-offshore. The swell is a solid 7 ft from the NE with a period of 7 seconds. The combined energy is 634, which is moderate, but the wind is glassy, clean, and the surf is rated as “very good.” The swell direction is NE, which is bang on the optimum for this break. This is the pick of the entire forecast. The size is still a bit much for beginners, but for intermediate to advanced surfers, this is going to be a crisp, clean wave on that reef. Keep in mind it’s inconsistent here, so you’ll be waiting for sets, but when they come, they’ll be worth it.
After that, the window closes. The following week is a mix of weak, short-period windswell from the E and ESE, with increasing onshore winds. There’s a long gap of several days with no real recommendations. The surf is small, choppy, and generally poor. The 16th and 17th see some tiny, clean waves, but they’re marginal at best.
So, if you’re planning a trip, pencil in Thursday the 10th. That morning is your best shot. The rest is a waiting game.
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.
