The Lowdown

G’day, Rusty here. Let’s talk about what’s coming up at Cape Toi.

First thing you need to know: the next week or so is flat and pretty ordinary. We’ve got a long dry spell ahead from today, Monday 17 August, right through until the morning of Monday 24 August. That’s nearly a full week of nothing worth getting excited about. Small, short-period windswell, mostly cross-onshore winds, and a few storms lurking around. The water’s sitting at 83°F, which is pretty much spot-on average for this time of year—nothing weird there, just your usual warm tropical bath.

Come Monday morning 24 August, there’s a little lift. The combined swell energy jumps to 204 (moderate) with a 3 ft Easterly swell at 10 seconds. The wind goes light and cross-offshore from the WNW, so it’ll be clean. Cape Toi is a reef break, inconsistent at the best of times, and exposed to the NE. This is a small window for the patient surfer, but it’s not a standout by any means.

Now, Tuesday 25 August morning brings a proper pulse. The combined swell energy hits 498 (moderate-strong) with a 4 ft swell from the SE, but the period is a very long 14 seconds—that’s groundswell. For a reef like Cape Toi, that long period means the waves will wrap in nicely and have plenty of shape. Morning wind is cross-offshore from the NE, so the face will be clean. The wave comment says good surf conditions, and honestly, this is the first real taste of quality in the forecast. It’s not huge, but for intermediate surfers, it’s worth a look.

The real standout, though, comes late in the window. Thursday 27 August morning: combined swell energy of 4431 (very strong), with an 8 ft ESE swell at 17 seconds—that’s an incredibly long-period groundswell. Wind is light and cross-offshore from the N. That’s a clean, powerful reef setup. The comment says excellent for experienced surfers, and at 8 ft, this is getting into expert territory. By the afternoon, it goes glassy with a 10 ft SE swell at 16 seconds. That’s the kind of session you tell your mates about—if you’ve got the skill.

Then Friday 28 August morning is exceptional. The combined energy is 6166 (very strong), with an 12 ft ESE swell at 16 seconds, and offshore wind from the WNW. This is expert-only stuff. The wave comment calls it exceptional for expert surfers. If you’re not comfortable in solid reef surf, stay on the beach for this one.

Saturday 29 August morning: the big dog. Combined energy of 14358 (very strong), with an 18 ft ESE swell at 16 seconds, and offshore wind from the NW. This is massive. The comment says exceptional for expert surfers, but the afternoon session has the wave comment warning that the swell is predicted to be too big for the break—20 ft with onshore wind. That’s a hard pass unless you’re a tow-in nut.

After that, it drops back through the end of August and into September, with still big 10 ft to 12 ft swells but the winds get messy and cross-onshore. Not the clean, lined-up stuff you want.

So, to sum it up: the best bet for most competent surfers is Tuesday 25 August morning—clean, long-period groundswell, moderate energy, and a reef that’ll handle it. For the experts, the absolute standout is the Friday 28 August morning session—clean, offshore, solid waves. Saturday 29 August is for the hardcore only.

Stay safe, respect the reef, and keep an eye on the sky.

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.
