The Lowdown
Alright folks, Rusty here with a look at what's coming up for Cape Toi. Let's be straight with you, it's been a rough patch lately.
We've got some real dross to wade through before we see anything worth paddling out for. A big storm system has been hammering the point, with Sunday the 6th seeing a massive 15-foot swell from the NE, but the wind is howling at 31 mph from the NE, turning the whole reef into a washing machine. The combined swell energy is a monstrous 3801, but with those conditions, it's a complete write-off for surfing. You'd be mad to go out.
Monday the 7th and Tuesday the 8th aren't much better. The swell drops but the wind stays strong and gusty, keeping things choppy and messy. The water temp is sitting at 84°, which is bang on average for this time of year, so at least the water feels fine.
Now, here’s where it gets a little interesting. Wednesday the 9th is our first real glimmer. Early morning, the wind goes glassy-light offshore from the NW at only 3 mph. We get a clean, 4-foot swell from the ESE with a decent 10-second period. The combined energy is a modest 328. It’s not going to blow your mind, but it’ll be the cleanest wave we’ve seen in days, with those offshore winds grooming the reef perfectly. This is your best bet for the near term, just don't expect a crowd-free party.
A heads up: the forecast for Wednesday the 16th of September looks promising. We’re looking at a 5-foot swell from the E, again with clean, light wind conditions. The combined energy hits a moderate 604, and the forecast says “very good surf conditions.” It's a week and a half out, so keep it on the radar but don't book the day off work yet.
Beyond that, the long-range forecast fades out into a lot of small, weak pulses with poor wind. The period drags, the energy drops, and those trade winds just won’t give it a rest. For the second week, there’s not much to get excited about, just small, messy dribble.
So, to sum it up: Sunday the 6th is a stormy nightmare. Wednesday the 9th is your best early-morning chance for clean, small waves. Keep an eye on the 16th of September as a potential standout further out, but treat it as a rumour for now. Hang in there.

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.
