The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for Cape Toi. Let’s just say, it’s a tough read, mate. The whole 16-day window is a bit of a battle. The wave energy is moderate for most of it, but the wind just won’t play ball. We’re looking at a long stretch of frustrating conditions.
The first real chance of something decent doesn’t come until Tuesday the 11th. The morning is the standout window. We’ll have a clean, 5ft east swell, but here’s the kicker: the wind is glassy, dead calm. That’s a rare treat for a spot that’s usually getting chopped up. The combined swell energy is moderate (555), coming from the east on a long 12-second period. This is a groundswell, so it’ll have some power. Being a reef break, it should handle that longer period better than a beach. The water is sitting at 84°, which is bang on average for this time of year. However, the break is *inconsistent*, so you’ll need to be patient. The crowds are *sometimes* an issue, so with it being clean, expect a few others with the same idea. For a Tuesday, you might get lucky. It’s the only true standout in the whole forecast.
After that glassy window, it’s back to the grind. The wind swings cross-shore or onshore for days, and the swell gets smaller and weaker. There’s a bit of a pulse on Wednesday the 19th morning. The swell is small, only 3ft from the east-northeast, but the wind is a light cross-offshore and the conditions are clean. The energy is weak (129), but if you’re desperate for a glide on a log, it’s the next best thing. It’s not a standout, just a ’maybe’ if you’re local.
Honestly, mate, for most of the period, the setup is more interesting for kite surfing than paddle surfing. The wind is just too strong and from the wrong direction. The periods with no real recommendation stretch for days on end. It’s a long wait for that one glassy Tuesday morning. Don’t hold your breath after that.
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.
