The Lowdown

Alright, Rusty here. Let's talk about what's cookin' for Cape Toi over the next couple of weeks.

Honestly, the outlook is a bit of a rough patch. We've got a lot of wind and messy conditions that make it tough to get good waves, and there are long gaps where you'd be better off doing something else. The first real chance of anything decent doesn't show up until Thursday morning, the 10th of September.

To be straight with you, the swell is often coming from the east or southeast, but the wind just won't play ball for most of it. For the first ten days or so, it's a whole lot of cross-onshore, onshore slop. We see a spike in size early on, around Tuesday the 1st and Wednesday the 2nd of September, with swell jumping to 8 ft to 12 ft from the southeast. That's a lot of water moving around, with the combined energy reaching a massive 2551 to 2598 (strong energy), but the wind is howling onshore at 22 to 25 mph from the southeast. That turns it into a lumpy, wind-ravaged mess. Honestly, with that kind of size and wind on a reef setup, it looks way more interesting for kite surfing than paddle surfing. That's expert territory, and the conditions are just plain ugly.

The only true standouts are the two mornings at the very end of the run. It’s a long wait.

Let’s break it down day by day. We start off with small, weak surf from the 29th of August through the 31st, with swell around 2 ft to 2 ft from the east. The wind is cross-onshore, and the combined energy is low, between 77 and 151 (weak energy). Not worth paddling out.

Then from the 1st to the 8th of September, it's all about wind and stormy conditions, with most days having a risk of thunderstorms. The swell gets bigger, but the wind is strong and wrong.

Now, for the highlight. On Thursday morning, September 10th, we get a brief window. It's early, but it's the best we've got. The swell will be pushing 5 ft from the east with a period of 10 seconds. More importantly, the wind is going to swing to the west-northwest at 9 mph, making it a clean, cross-offshore breeze. The guide says the conditions will be "clean." The combined energy sits at 379 (moderate energy), so there's a bit of push. It's not a monster day, but after all that chop, it’ll feel like a gift. Keep in mind, Cape Toi is a reef break that can be inconsistent, so don't expect a party wave every set. Crowds are possible here sometimes.

The following morning, Friday the 11th of September, has a bit more size, with the swell hitting 6 ft from the east with a longer period of 13 seconds. The combined energy kicks up to 1041 (strong energy). The wind is from the east-northeast at 9 mph, which is cross-onshore and will make it a bit choppy. It’s a step down in quality, but if you miss Thursday, it's your next best look.

Saturday morning, September 12th, the swell holds at 6 ft from the east, but the period drops to 12 seconds. The wind is light from the east-northeast at 6 mph and cross-shore, so it won't be completely blown out. The energy is still strong at 930. It's a marginal call, but could be rideable.

As for the water, it's about average for this time of year here, so no need for a thicker suit just yet.

So, to sum it up: the real window to look at is that Thursday morning, September 10th for the cleanest conditions. Friday the 11th and Saturday the 12th are back-ups. The rest of the forecast is a write-off.

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.
