The Lowdown

Alright folks, Rusty here. Let’s take a hard look at Cape Toi. I gotta be straight with you – this 16-day window is a real test of patience. The first week and a half is a write-off, honestly. From Saturday the 8th all the way through to Saturday the 15th, it’s a long stretch of poor conditions. Cross-onshore winds are the norm, and the swell is either too big and raw, or too small and weak. The wind is howling out of the east at 28 mph on Saturday the 8th, with a big 13.1ft swell, but it’s all cross-on and messy – a total no-go. That trend continues, with the wind easing but staying cross-on, and the swell dropping from 8.2ft to under 3.3ft through the week. The energy is moderate to strong at times, with a combined energy of 2481 on that Saturday, but it’s all wasted on choppy, lumpy conditions. You’re better off saving your wax.

Now, after that long slog, things finally get interesting. The standout is the morning of Sunday the 16th of August. This is the one to circle on the calendar. We’ve got a clean 6.6ft swell from the ENE, with a period of 12 seconds – that’s a proper groundswell with some grunt. The combined energy is a solid 1058, so it’s got real push. The wind? Glassy. Dead calm. That’s a massive positive for a reef break like Cape Toi, which needs that offshore or glassy window to really shine. This is the best on offer, hands down. It’s a bigger wave, so it’s for the experienced crew; beginners will find it too much. The water temp is sitting around 28.8°, which is about average for this time of year, so no surprises there.

The following day, Monday the 17th, still has some decent size at 5.9ft from the ENE, but the wind swings around to a light cross-shore, so it won’t be as clean as the Sunday glass-off. The energy is still good at 979, but it’s a step down in quality. After that, the swell fades fast through the rest of the week, dropping below 3.3ft, and the wind stays messy or cross-on. By the 22nd and 23rd of August, we’re looking at tiny, weak swell with a combined energy down in the 40-80 range, and fresh cross-shore winds. Not worth paddling out for.

So, to sum it up: the first 8 days are a bust. Then you get a fantastic window on Sunday morning the 16th – that’s your moment. After that, it’s a slow fade into nothing. Keep your eyes on that Sunday, and don’t bother with the rest.

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.
