The Lowdown
Alright folks, Rusty here. Let’s suss out what we’ve got coming our way for Cape Toi. It’s a reef setup that’s inconsistent, so don’t hold your breath for perfect waves just yet.
The first half of this outlook is a bit of a write-off. From Friday the 28th of August right through to Tuesday the 8th of September, we’re looking at poor surf conditions. The wind is mostly onshore or cross-onshore, and while we do get some east-northeast swell at times, the combined wave energy is weak to moderate, and the quality just isn’t there for a proper paddle.
The real action doesn’t start to show until Wednesday the 9th of September. That morning, we get a standout with an ESE swell of about 7ft riding on a decent 10-second period. The combined energy kicks right up, and with a light cross-offshore breeze, it’s going to be clean. This is for the experienced crew – that’s a solid, powerful wave on a reef. The water temp is about average for this time of year, no big anomalies to report.
Then, Friday the 11th of September morning is the other standout to circle. We’re looking at a 10ft SE groundswell with a light offshore wind from the northwest. That’s glassy, clean conditions on a reef that handles that direction well. It’s another expert-only session, but for those who can handle it, it’s going to be firing. Expect it to be a bit inconsistent and crowds are possible.
Between those two standouts, there’s a marginal period with a few sessions on Thursday the 10th, but the wind isn’t as clean. For the rest, the second week shows a few other sessions with some size, but the winds are just messy or onshore, blowing out what could have been a good wave.
So, to keep it simple: the first ten days are a bust. The highlights are the morning sessions on the 9th and the 11th of September. Those are your best bets for some real quality.
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.
