The Lowdown
Howdy, Rusty here, giving you the surf outlook for Cape Toi. This is a reef break that’s open to the swell, but it’s inconsistent, so you’ll need to pick your spots. The water’s sitting at 82°, which is about normal for this time of year.
The first stretch is rough. From Wednesday the 9th through most of the next week, it’s mostly junk – small, short-period, and cross-windy. The mornings of Friday the 11th and Sunday the 13th have some clean, cross-off wind, but the waves are barely knee-high, with combined energy around 226 to 240 (weak). Not much to get your heart racing.
Then on Tuesday the 15th of September, things get interesting. The wind goes glassy in the afternoon, and there’s a clean 1.3m ESE swell at 9 seconds. The combined energy is 415 (moderate). It’s a small wave, but it’s clean and glassy – that’s your best bet for a fun, easy session in the first week. The reef will handle it fine.
The big one hits on Saturday the 19th of September. There’s a serious SE groundswell at 3.0m to 3.5m, with a period of 16 to 17 seconds – that’s super long-period energy. The combined energy is huge, up to 6873 (very strong). The wind is cross-shore from the NE, so it’ll be lumpy, but the power is massive. Over 2.5m is experts-only, so this is a heavy-duty day. The reef at Cape Toi will work with the long period, but it’s a raw, intimidating wave.
The following week, Monday the 23rd of September offers a cleaner setup. The morning has a giant 4.5m SE swell at 12 seconds, with clean cross-off wind from the W. Combined energy is 5201 (very strong). That’s a huge, clean wave – only for the skilled. The afternoon drops to a 2.4m NNE swell at 11 seconds, still clean, with energy at 1386 (strong). That’s a more manageable size, but still a solid, powerful wave. The break can get crowds “sometimes,” so keep an eye out.
The best sessions are the clean glassy Tuesday the 15th and the raw, big swell Saturday the 19th. The rest is a lot of waiting. The break is inconsistent, so don’t expect a constant stream of waves.
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.
