The Lowdown
G’day, I’m Rusty, and I’ve been looking over the Cape Toi charts. Honest truth – most of the next 16 days is a write-off, but there’s maybe one day that’ll get the blood pumping.
The forecast starts Thursday 13 August and it’s basically flat. Swell is only 2ft, wind is messy, and the combined energy is weak (80). That same poor pattern holds day after day through to around 24 August. There’s a long dry spell here – from 13 August right through to 23 August – where the waves stay small and wind-affected. Nothing worth chasing.
Saturday 15 August shows a slight bump to 3ft from the ENE, but the wind is cross-onshore and it’s still only marginal. Don’t get your hopes up.
The one real standout is Tuesday 25 August. That morning we get a solid 8ft from the SE with a 14-second period. The combined energy jumps to 2755 (strong). That’s a proper groundswell hitting a reef, and it’s big. The wind is a moderate cross-shore, which isn’t glassy but it’s rideable. The swell direction is off the optimum of NE, but for size and energy, this is it. That afternoon drops to 7ft and 13 seconds, still beefy. This is expert territory – 8ft on a reef isn’t for the faint-hearted. The crowds can show up sometimes, so don’t expect to have it to yourself.
After Tuesday 25 August, Wednesday 26 August drops back to 5ft and the onshore wind returns, and it’s back to poor conditions for the rest of the run.
So the only date worth circling is Tuesday 25 August. The rest is a waiting game.

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.
