The Lowdown
Alright, this is Rusty, and I'm looking at the surf outlook for Cape Toi. It's a reef break, exposed to swells, and we've got a bit of a wait on our hands for any kind of decent session.
The first week is mostly a write-off. We've got some swell on the charts, but the wind is just all wrong. From Wednesday the 2nd right through to the end of that first week, it's a mess of cross-onshore and strong cross-shore winds, mostly from the NE or ENE, pumping at 12 to 28 mph. The wave comment says it all: "poor surf conditions." There's energy there, with combined energy values hitting up to 2771, but it's choppy and lumpy. Not worth paddling out. There's a few marginal calls, but honestly, nothing to get excited about. This is a solid week of bad surf.
Then we start seeing some light. On Monday the 7th, the wind finally turns favourable. We get a clean morning with a cross-offshore breeze from the NNE at 22 mph, and a 8 ft east swell with a 9-second period. The combined energy is a solid 1004, and while the surf conditions are still just "marginal," that's a huge step up. Tuesday the 8th looks even bigger, with a 10 ft swell from the ESE, a long 11-second period, and cross-offshore winds again. The energy is high at 2080, but that size is getting into expert territory. Wednesday the 9th keeps it clean with cross-offshore winds, but the swell drops. It's all building to something.
The real standout, the one to circle on your calendar, is the weekend of the 14th and 15th. On the morning of Tuesday the 15th, we see a 10 ft east swell with a 10-second period and gentle cross-shore winds. But the afternoon of the 15th is the big one: a massive 16 ft east swell with a very long 14-second period, and light cross-onshore winds from the east at just 6 mph. The combined energy is an incredible 10230. That is serious, powerful groundswell. Then on the 16th of September, Wednesday morning, we get glassy conditions with a 15 ft east swell and a long 13-second period. The wave comment says "exceptional surf conditions for expert surfers" and I have to agree. That's as good as it gets here, but it's huge. This is for experienced chargers only. The 17th cleans up with an 8 ft east swell, a 12-second period, and offshore winds from the NNW. That's a quality day for strong intermediates.
For the standout, I'm picking Wednesday the 16th of September. Cape Toi is a reef, and with that 15 ft east swell and very long period, it will be a full-on, heavy wave. The glassy conditions and the "exceptional" call make it the best on offer. But if that's too big, the morning of Tuesday the 15th with the 10 ft east swell is a solid option, and the 17th with offshore winds is a great, clean day for advanced surfers. The water temperature is a warm 84°°F, which is about normal for this time of year.
Alright, that's the long-range look. It's a slow start, so be patient. The end of the second week is where the magic happens.

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.

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.
