The Lowdown
Alright, Rusty here, let’s have a look at what’s on the table for Cape Toi. This reef setup is a bit of a tease – it’s got the potential for some proper waves, but the wind and the size are going to make you work for it. The water temp is about average for this time of year, so no surprises there.
We start off with a bit of hope on Tuesday the 15th of September. The morning has clean, 5ft swell coming from the ESE with a period of 10 seconds and the combined energy sitting at a solid moderate 495. That northwest wind is offshore, keeping things glassy. It’s a small window of clean surf, but it’s there. Afternoon turns a bit messy with a light cross-onshore wind, so the morning is the go.
Wednesday the 16th sees the swell drop to 3ft, but it’s a long-period 14-second groundswell from the ENE. The morning has a cross-offshore wind, so it’s clean and rideable, even if small. The energy is still moderate (480). This is a good option for a longboard or a funboard, and the reef will help shape that long-period energy. It’s inconsistent here, so don’t expect a wave every minute, but the ones that come through will be sweet.
From Wednesday afternoon right through to Friday the 18th, the wind goes onshore and the surf gets lumpy and messy. We’ve got a fresh to strong breeze ruining things, so you’re better off doing something else.
Now, here’s where it gets wild. Saturday the 19th of September, the swell starts to pump up. Morning sees 12ft from the ESE with a very long 16-second period. The energy jumps to a strong 7858. The wind is cross-offshore, so the face is clean, but 12ft at a reef is for experienced surfers only. This is a standout session for the brave. The afternoon is bigger at 13ft but with a cross-shore wind, so the morning is the pick.
Sunday the 20th is a monster. 20ft swell from the east with a 15-second period. The combined energy is an extreme 15225. The wind is cross-offshore and clean in the morning. This is not for beginners; this is for experts only. The swell is too big for this break, according to the forecast, so unless you’re a charger, stay on the beach. The afternoon gets messy with a strong cross-shore wind.
Monday the 21st keeps the big swell going at 18ft to 20ft, but it’s now accompanied by a near-gale cross-shore wind. This is blown out and dangerous. Kite surfers might have a field day, but for paddle surfing, it’s a no-go.
The rest of the week into the following week is a write-off. From Tuesday the 22nd through to the end of the month, we have a mix of onshore gales, strong cross-shore winds, and a drop in swell quality. The swell sticks around at times, but the wind is relentless. There’s a brief moment on Wednesday the 23rd afternoon with clean 7ft, but the period is short (7 seconds) and the energy is weak (411). Not worth the drive.
The standout is Saturday the 19th morning for the big, clean, long-period groundswell. Sunday the 20th morning is the other one if you’re a real charger. Everything else is either small, windy, or too big and messy.
Rusty out.

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.
