The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for Cape Toi over the next couple of weeks. It’s a bit of a slow start, so don’t rush down just yet. The real magic is brewing for later.
We’ve got a patchy run ahead. The first proper chance to get wet won’t really show up until Monday the 14th, and even then it’s not the main event. The swell is tiny and the wind is a bit messy early on. There’s a decent run of poor conditions mid-week that you’ll want to sit out. The good news is, a proper pulse of energy is set to arrive, and it’s worth waiting for.
The standout window is shaping up for Sunday the 20th and Monday the 21st. That’s where the real focus should be. The water temp is sitting around 82°F, which is pretty much spot on for this time of year, so no surprises there.
Let’s get into it.
The first waves worth a mention come on Monday morning the 14th. Cape Toi will have a clean, glassy 4ft swell from the ESE with a short period of 9 seconds. The energy is moderate at 337. It’s a nice little morning session for the keen, but nothing to write home about.
The surf picks up a touch on Tuesday the 15th. The morning offers a glassy 5ft from the ESE, period up to 10 seconds, and the combined energy jumps to a solid 543 – that’s moderate energy, but getting stronger. There’s a risk of thunderstorms around, but with glassy conditions, you might score a few clean ones before the wind gets tricky. The afternoon stays glassy with 5ft.
After that, things go quiet. From Wednesday the 16th through to Friday the 18th, it’s a write-off with messy, cross-shore winds and weak, short-period swell. The energy drops well below 300. Not worth paddling out.
Saturday the 19th sees a massive spike in energy, but it’s wild. The morning is a raw 10ft from the ESE with a long 16-second period. The combined energy rockets to 4486 – that’s strong. But with a fresh 19 mph cross-shore wind, it’s lumpy and only for the brave. The afternoon cleans up a little with a cross-off breeze, still 12ft and 16-second period, energy at 5820. It’s still marginal but has some power behind it.
Now, here’s the real standout. Sunday the 20th is building into something special. The morning has a solid 15ft ESE swell, 15-second period, and a massive 8860 energy reading. The wind is cross-off from the north at 12 mph, keeping things clean. This is big, powerful surf. At over 8ft, it’s for experts only. The afternoon sees the swell hitting 18ft from the east, energy at 12043 – that’s very strong. The wind picks up to 19 mph but stays cross-off. The wave quality is clean. This is the kind of day you tell stories about, but only if you’ve got the skill.
Monday the 21st is the absolute pinnacle. The morning session is pure gold: a clean 18ft east swell with a 14-second period and energy at 11565. The wind is offshore from the WNW at 9 mph, giving you that perfect, groomed face. This is exceptional for experts, full stop. The afternoon drops to 15ft, but the wind swings onshore from the SE, so the morning is where you want to be.
After that, the swell backs off quickly. Tuesday the 22nd sees a drop to 6ft with messy cross-shore winds. Wednesday and Thursday are poor, with strong cross-shore winds and short-period junk. By Friday the 25th, things start to look a bit more interesting again with a clean 8ft from the ENE and light cross-off winds – energy at 998 – that’s a decent option for experienced surfers.
The last few days of the period, around the 27th and 28th, offer some clean, glassy conditions with 6ft ESE swell and long 13-14 second periods. Energy is moderate to strong, up around 1864. The wind is light and glassy, making for some lovely clean waves, though the swell direction is a bit more easterly. A nice way to round things out.
So, the big call: if you can only pick one day, make it the morning of Monday the 21st of September at Cape Toi. That’s the one with the offshore wind, the huge clean swell, and the kind of energy that makes your heart race. The Sunday before is also incredible, but the Monday morning has that extra bit of magic. Just remember, it’s expert territory. For the rest of us, the glassy mornings around the 14th and 28th are your safer bets.
Stay safe and get after it.

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.
