The Lowdown
Alright, Rusty here. Let's take a look at what's cooking for Cape Toi over the next couple of weeks.
Alright, mates, the first half of this forecast window is pretty grim. For the next week and a half, from now through the 18th, it's mostly flat or choppy junk. We're looking at a long, quiet spell with hardly anything worth paddling out for. The swell is tiny, under 3 feet most days, and the wind is mostly cross or cross-onshore, just chopping everything up. There's a bit of a pulse on the 15th where the wind turns light and cross-offshore, and you might snag a knee-to-waist high wave, but it's barely a blip.
Then things start to get interesting. A big jump in energy is forecast from the 19th (Saturday) onwards, but it comes with fresh, lumpy cross-shore winds, so it’s messy for a few days. The real standout, the one to circle on your calendar, is Friday the 25th. That morning, Cape Toi is looking absolutely firing. The swell is pumping at a solid 13 feet from the SE, with a very long period of 17 seconds. That’s a proper groundswell with some serious grunt. The wind is light and cross-offshore, making for clean conditions. Combined energy is massive at 8602, this is big, powerful surf. The water temp is about 82°F, which is pretty average for this time of year. This is expert territory for sure, way too big for beginners. This is the one to plan for.
Before that, the morning of Thursday the 24th also looks promising, with a 10-foot SE swell and clean offshore winds from the west. That’s another good option for the experienced crew.
The following morning, Saturday the 26th, the swell is still solid at 12 feet from the ESE with a light cross-offshore breeze, offering more quality waves for those who can handle it, though it starts to get a bit lumpy by the afternoon.
So, to boil it down: it's a waiting game. The first 12 days are a write-off. Keep your eye on Thursday the 24th and Saturday the 26th, but Friday the 25th is the clear winner – that morning is the one to chase if you want to get barreled at Cape Toi. Just be ready for a crowd, because it's a spot that can get busy when it's good.
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.
