The Lowdown

Alright folks, Rusty here. Let’s break down what’s coming our way. We’re focusing on one spot that has built a bit of a reputation: Cape Toi. But it’s not all plain sailing, so let’s get into it.

The forecast starts with a bit of a slow grind. Early Monday morning (the 10th) we see some east swell at about 6 ft, but the wind is coming from the east at 9 mph, putting us in a cross-on situation that leaves things fairly choppy and messy. The combined energy is pumping at (1094) which is a strong number, but the quality just isn’t there. It looks more like a wrestling match than a wave session. Through Monday afternoon, that 5 ft east swell sticks around but the conditions are poor. Not a good start.

But hope arrives on Tuesday morning, the 11th of August. The wind swings around to a light north at just 3 mph, going glassy. The swell drops a bit to 5 ft from the east with a 12-second period. This is the standout window. The glide is there, the surface is clean, and expectations are high. This is where you want to be in the water. The water temperature is sitting at 84°, which is pretty much average for the time of year—no surprises, just warm.

Tuesday afternoon sees the wind shifting south and cross-on again, making it marginal, so catch that morning session.

The rest of the week through to the weekend (Wednesday 12th to Sunday 16th) is a mixed bag. Wednesday morning is cross-shore and building a bit of chop. Things dip significantly by Thursday when the swell drops to under 3 ft and the energy plummets. Friday and Saturday are small and onshore-leaning—it’s a bit of a dead period.

Now, Sunday the 16th offers another flicker of hope for the morning. A north-northeast breeze at 6 mph gives us a clean, cross-off wind, and the swell holds around 3 ft from the east. It’s not huge, but it’s surfable and tidy. If you missed Tuesday, this is your second chance.

Through the second week, it gets a bit bleak. Monday 17th to Wednesday 19th is mostly choppy and onshore, with the wind ramping up. The swell is there (around 4 ft to 5 ft) but the wind just spoils it. Thursday 20th and Friday 21st are small and not worth the paddle.

Then on Saturday 22nd August morning, we get a hint of something again. A light west-northwest wind at 3 mph gives us clean conditions on a tiny 2 ft swell. It’s ordinary but clean. Sunday 23rd morning is similar. But the real last chance is Monday morning the 24th of August: glassy conditions with a west-northwest 3 mph wind, 3 ft of east swell (9-second period, not long but okay) and the energy hits a moderate (200). It’s clean, it’s small, but you could get a fun one if you pick your wave.

All in all, the standout is clearly Tuesday morning the 11th of August. Glassy conditions and chest-high east swell. If you can paddle out then, do it. The rest of the window is mostly small, messy, or blown out, with a few clean morning opportunities later on that are more for the patient surfer.

Remember, Cape Toi is a reef break—it can be inconsistent, though we do have some consistent pulse here for the first couple of days. It’s exposed to the swell, so it picks up what’s there.

Stay safe 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.
