The Lowdown
Alright, Rusty here, let’s break down what’s coming for Number Threes.
The water temp is 81°F, with a tiny anomaly of 0.7°F – pretty much normal for this time of year.
The first few days are a bust. Sunday the 2nd and Monday the 3rd have some swell, but the wind is blowing 15 to 22 mph from the ENE, cross-off, and the quality is poor. The swell is short period, around 8 seconds, and the energy is moderate. Just not worth it.
Tuesday the 4th is the first real chance. The swell drops to 5ft from the ENE, but the period stretches to 11 seconds, and the wind drops to a light 9 mph. The energy is still moderate, and the forecast says “expect good surf conditions.” It’s clean, but expect crowds – this spot gets busy often.
The big one, the one you want to save your energy for, is Monday the 17th of August. The morning brings a solid 10ft of ENE swell, with an 8-second period, and the wind is light from the NE at 9 mph. The combined energy is strong at 1432. In the afternoon, it drops to 8ft, but the wind eases even more to a light 6 mph. The forecast says “excellent surf conditions for experienced surfers.” This is expert territory. The reef will handle the power, and the cross-off wind keeps it glassy. The short period means frequent sets, but it’s going to be a proper session.
Between now and then, it’s mostly small and windy. From the 5th through the 16th, the swell is tiny, the wind is fresh to strong, and the scores are low. The 12th and 13th have some long-period groundswell from the south (17 to 18 seconds), but the wind is still up and the waves are only 3ft to 4ft. Not worth paddling out for.
So, in short: hit Tuesday the 4th for a clean, smaller session, and then circle Monday the 17th of August. That’s the day. Big, clean, and powerful. Bring your A-game.
Rusty.

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.
