The Lowdown
Alright folks, Rusty here. Let’s have a look at Cape Toi. It’s a reef setup over here, and the next couple of weeks are a bit of a mixed bag, to be honest. We’ve got some proper sized swell coming through, but the wind is gonna be a real pain for most of it.
Right now, there’s nothing going on. The first bit of surf worth talking about doesn’t show up until Tuesday the 25th of August. That morning, we see a big jump in size with a 15ft swell from the southeast, but it’s coming with a strong 35 km/h cross-shore wind. The wave energy is massive (11490), but the wind is going to make it lumpy and cross-chop. It’s big and powerful, but not clean. The afternoon is even bigger at 16ft (14169 wave energy), but same story – the wind is just too strong for it to be any good. This is really only for the experts, and even then, it’s gonna be a battle.
The real standout window is a bit further out, and it’s a classic case of waiting for the wind to drop. Keep your eye on Tuesday the 1st of September. The morning session is looking like the pick of the entire forecast. We’ve got a 4ft swell from the east, with a nice 13-second period, and the wind is dead calm – glassy. The wave energy is a solid 754, and it’s pushing right into the reef. This is going to be clean, lined-up, and proper. The best waves on offer.
Before that, Monday the 31st of August morning is also worth a mention. It’s smaller, around 3ft from the southeast, but with glassy conditions as well (271 wave energy). It’s a good warm-up for the Tuesday.
The water temperature is sitting around 84°, which is pretty normal for the time of year here, so no surprises there.
For the rest of the period, there are a few other days with swell, like Wednesday the 2nd of September with 8ft (1259 wave energy), but the wind is onshore or cross-shore and choppy. It’s just not the same quality. The last day with any real hope is Saturday the 5th of September morning, with a 7ft easterly and a clean cross-offshore wind. That could be a fun session, but it’s a long way out and the wind forecast might change.
So, to sum it up: the first week is a write-off for clean surf. The second week has a couple of golden windows, especially Tuesday the 1st of September. That’s your day. Get out there.
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.
