The Lowdown

Alright, Rusty here, let’s have a look at what Number Threes is cooking up for us.

Right off the bat, I gotta be straight with you – the next week and a half is looking pretty grim. There’s a solid week of poor surf from the 29th of August through to the 5th of September. The wind is stubborn, blowing cross-off from the ENE at a solid 19 to 25 mph, which just wrecks the shape. The water temp is sitting at 81°, which is normal for this time of year. The energy is moderate for most of it, but with short-period 7 to 8 second windswell and that onshore kick, it’s just not giving us anything decent to work with. Honestly, it’s a write-off for a paddle.

Now, there’s a glimmer of hope on the 6th of September. That Sunday afternoon shows a real spike: a 13 ft ENE swell at 11 seconds. That’s got strong to very strong energy behind it. But here’s the catch – it’s still blowing 28 mph cross-off from the NE. That size (over 8 ft) is experts-only territory. With that wind, it’s going to be a bumpy, challenging beast of a session. For most of us, this setup actually looks more interesting for kite surfing than paddle surfing.

After that little spike, things drop back down into the marginal zone through the 7th to the 9th of September, with the swell fading from 7 ft down to 3 ft. The period does get interesting on the 2nd and again on the 11th and 12th of September, with some S and SSW swells pushing 15 to 16 seconds – proper long-period groundswell. But the heights are small (2 ft to 3 ft), and the energy is weak to moderate. That low energy combined with the cross-off breeze means the waves just won’t have any push.

Looking right out to the end of the forecast, the 13th of September shows a slight easing in the wind. We get a gentle breeze from the E at 9 mph, turning cross-shore. The swell is still tiny (2 ft) and from the SSW (optimum is SSE), but it’s the most relaxed conditions we’ve seen. It’s flat, but at least it’s flat and clean.

So to sum it up: there are no true standouts here. The only real pulse of size comes on the 6th, but it’s blown out. Everything else is small, windy, or both. If you’re thinking about a paddle, maybe keep an eye on that last couple of days – the wind finally drops, but you’ll need a foamie for ankle-snappers. For now, I’d grab a beer and watch the horizon.

Information about the Number Threes Surf forecast

The above surf forecast table for Number Threes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Number Threes can be found by selecting the local surf guide option on the grey menu. Our Number Threes 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 (Number Threes) 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 Number Threes 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.
