The Lowdown
Alright folks, Rusty here. Let me break down what we’ve got over at Cape Toi. It’s a reef setup, pretty exposed, and it likes swell from the NE. We’re in for a long dry spell before things get interesting, so don’t get too excited just yet.
The first week and a half is basically a write-off. From Tuesday the 8th right through to Monday the 21st of September, there’s nothing I’d paddle out for. Winds are all over the place, mostly cross or cross-off but with flashes of strong breeze and onshores, and the poor surf quality tag is a running theme. Short, weak, messy swells with low periods mean you’d be fighting a washing machine, not surfing. Cape Toi is inconsistent at the best of times, and this stretch proves it. You’d be better off staying home or checking the kite forecast if the wind gets up – some of those afternoons look more interesting for a kite than a surfboard.
Now, the standout. Mark your calendars for Monday the 21st of September, morning session. This is the one. We’ve got a serious groundswell hitting – 12 ft from the ESE with a very long 18-second period. That is pumping. The combined energy is off the charts at 7703, and the wind is light offshore from the NNW with clean conditions. This is big, powerful swell, over 8 ft, so it’s strictly for experienced surfers only – this is expert territory. The only caveat is that long-period swell like this can close out beach breaks, but Cape Toi is a reef, so it should handle it. Expect clean, lined-up waves and long waits between sets. Crowds are possible here, so get there early.
Tuesday the 22nd morning is still very solid – 10 ft from the ESE, 16-second period, light offshore cross-off breeze. Still excellent for experienced surfers, but the swell is coming down a notch. Combined energy is still massive at 4744.
Wednesday the 23rd morning offers a cleaner option for the slightly smaller crew: 6 ft from the E at 13 seconds, glassy conditions. That’s beautiful for a mid-week session, though the swell is dropping. Good for intermediate surfers.
So there you go. A whole bunch of nothing, then a couple of days of proper swell for the crew that can handle it. The long-range stuff on the 21st and 22nd is the real deal, but as always with a two-week outlook, we’ll have to see how it firms up.
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.
