The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming up for Cape Toi over the next couple of weeks.

First things first, this is a reef setup that’s exposed to the north-east. It’s an inconsistent spot, so when it does line up, you want to be on it. For the time of year, the water temperature is about average, nothing wild there.

Honestly, the next week is a bit of a grind. There’s some small swell hanging around, but the wind keeps messing it up. The best chance to get wet before things kick off will be Tuesday morning, 15th September. That’s the standout in the first half. Swell is coming from the ESE at around 5ft, with a period of 10 seconds—decent energy (495) for the size. The kicker is the glassy conditions. Zero wind. It’s gonna be clean as a whistle. That’s your window for a fun session on this reef.

After that, the wind turns onshore or cross-shore and a lot of the small swell gets chopped up. We get a couple of small windows through Wednesday and Thursday, but the wind is just not playing ball. Surf quality will be marginal at best.

Now, looking further out, there’s a big pulse of energy brewing. Saturday afternoon, 19th September, a serious swell starts to show. We’re talking ESE swell running up to 8ft, with a very long period of 16 seconds. Combined wave energy is eye-watering at 4865. That is a lot of water moving. The wind is cross-offshore, keeping it clean, but this is expert territory. That size and that long period will make it pitchy and powerful on the reef. This is way too big for beginners. The crowd factor is “sometimes” here, but on a Saturday with this much swell, expect some company.

The swell just gets bigger and more unruly after that. Sunday morning, 20th September sees the peak of the energy with a massive 18ft east swell at 15 seconds. Combined energy hits 13446. The problem? Strong cross-winds at 25 mph. It’s going to be a messy, dangerous beast. Unless you’re towing in or on a gun, it’s a day to watch from the cliff. The conditions smooth out slightly on Monday, but it’s still huge and messy.

For a reef break like this, that long-period groundswell (over 11 seconds) will be drawing lines nicely, but with the size, it will be closing out or breaking very heavy. The beach breaks nearby would be a washing machine with these periods.

There is a gap of several days with no real recommendations after the big swell fades, through to the end of the month. The swell energy drops right off, but the wind stays strong and cross-shore, so it’s just blown-out dribble for a while.

So, to wrap it up: your best bet is Tuesday morning, 15th September for a clean, fun session. If you are an expert looking for a serious challenge, keep an eye on Saturday afternoon, 19th September, but know it’s a big, powerful wave. For everyone else, that Tuesday is the one.

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.
