The Lowdown
Alright, Rusty here. Let's get into it.
Look, I've been staring at the charts for Cape Toi, and I gotta be straight with you – it's a tough run ahead. This reef break is exposed to the east-northeast, and for the next week and a half, the wind is just not playing ball. We’re looking at a long stretch of frustrating conditions.
Starting Sunday the 30th of August right through to Thursday the 10th of September, it’s a write-off. We’ve got tiny swell of 2ft to 2ft mixed with cross-shore and onshore breezes that are just chopping everything up. The wave energy is weak, barely hitting 110 (combined swell energy), and the conditions are described as poor. Not a single wave worth paddling out for.
Then there’s a period from Tuesday the 1st of September through to the 9th where the swell actually jumps up – we’re talking 5ft to a solid 10ft. The energy gets strong, hitting four-digit numbers like 1997 on the 6th. But here’s the kicker: it’s all coming with strong onshore wind from the east, making for lumpy, choppy, and poor surf. At 10ft, that’s expert-only territory, and with that wind, it’s more of a kite-surfing setup than a paddle-surfing one.
Now, there is a light at the end of the tunnel. Friday the 11th and Saturday the 12th of September, we finally get a window. On Friday morning, we’ve got a 6ft swell rolling in from the east-northeast with a period of 10 seconds. The wind swings to a light north-northeasterly at 3 mph, giving us a clean, cross-offshore flow. Wave energy is a solid 696 (combined swell energy). Saturday morning looks even better – a 7ft east swell with a clean north-northwesterly breeze at 6 mph. These are the only two sessions that rate as "very good surf conditions." Cape Toi is *inconsistent* normally, so when it lines up like this, you don’t miss it. Crowds are *sometimes* a thing here, so you might see a few others in the water.
After that, Sunday the 13th drops back to a tiny 0.7ft swell with a very long 14-second period, which at a reef will just be a dribble, and Monday the 14th has a 1.0ft offshore breeze but no real power. So, your window is tight. Friday the 11th morning and Saturday the 12th morning are your standouts – the best on offer. Get amongst it while you can.

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.
