The Lowdown
Alright folks, Rusty here. Let’s talk Cape Toi, and be straight with you – the first week is a write-off.
Water’s about 85°, dead average for the season. But the wind? Forget it. Near gale force cross-shore and onshore winds ripping through, with swell pumping 6 to 8 feet plus – but it’s all blown out, messy, and not for paddling. That’s kite-surf territory if anything.
The first real window opens on Thursday, August 13th. Morning shows a light 6 mph breeze from the NNE, blowing cross-offshore. Clean as a whistle. Swell sits around 5 ft from the ENE, with a 12-second period – that’s a proper groundswell with some grunt. Energy is moderate at (788). This break, Cape Toi, is a reef and it’s inconsistent, but when it’s like this, it’s the pick of the fortnight.
Thursday afternoon holds clean too, swell bumping to 5 ft from the ENE, wind from the WSW at 9 mph, still cross-off. Energy ticks up a notch to (813). This is your window if you’re intermediate and keen for a clean reef wave.
After that, we fade out. Friday the 14th is smaller and not worth the drive. The weekend and into the following week is back to choppy, onshore junk and marginal conditions.
The standout is clear: Thursday morning, August 13, at Cape Toi. That 5 ft of groundswell with clean, light wind is the best you’re gonna get. It’s a fickle wave, but when she lines up like this, she’s worth the wait.
That’s the story from here.
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.
