The Lowdown
Alright, folks. Rusty here.
Let’s talk Cape Toi. The water is running about 84°F, which is pretty normal for this time of year.
The 16-day forecast has a rough start. Monday the 7th brings a strong pulse of swell, about 8ft from the ENE, with a lot of energy behind it (1212). But the wind is a messy cross-off at 19 mph, and the period is a short, lumpy 8 to 9 seconds. It’s going to be a messy session. Tuesday the 8th is cleaner, with waves around 7ft to 6ft, but the period is still short, and the quality is poor.
Then we hit a real dry spell. From Wednesday the 9th all the way through to Saturday the 19th, it’s mostly small, weak, and poor. You’ll see waist-high waves with periods under 10 seconds, and energy readings mostly in the low hundreds or below. The wind is a mixed bag, but it’s never really good. There’s a brief moment on Thursday the 17th afternoon where it goes glassy, but the swell is only 3ft. It’s rideable, but not a highlight.
The best window, if you’ve got the patience, is Sunday the 20th. The morning shows a 6ft NE swell with a clean cross-off breeze from the west at 9 mph and moderate energy (295). It’s not huge, but it’s the first clean, sorted-out day in nearly two weeks. Cape Toi is a reef, so it’ll handle that longer period well. Just keep in mind crowds can be a thing here.
Monday the 21st still has some size, about 6ft from the ENE, but the wind picks up, making it a gamble. After that, it fades into small, crummy conditions.
So, here’s the deal: the first week is a miss. The real target is Sunday the 20th. If you can hold out, it’s the best call in the whole 16 days.
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.
