The Lowdown
Alright, let me break down what’s happening at Number Threes for you.
The water’s sitting right around 80°F, which is dead on average for this time of year, so nothing weird there.
First few days – from Friday the 24th through Monday the 28th – it’s mostly a grind. You’ve got swell from 7 ft down to 5 ft, but it’s short-period windswell at 7-8 seconds, and the wind is blowing hard out of the ENE at 18-25 mph. The energy is moderate to strong, in the 1049 to 1273 range, but that short period and strong cross-off wind means messy, choppy conditions. Tuesday the 28th brings a bigger pulse – 7 ft to 8 ft from the east with period up to 13 seconds, and energy jumps to 1673 and 1934 – that’s serious energy – but wind is still fresh cross-off.
Now, Wednesday the 29th is where you need to be. Swell drops to 2 ft, but it’s from the south with a 14-second period, and the wind goes glassy – barely 3 mph out of the west. Energy is low at 217, but that’s a classic long-period groundswell and it’ll be glassy clean. That morning is the best session in this whole 16-day forecast. The reef at Number Threes is consistent and exposed, so with that period and zero wind, the waves will have shape. The afternoon goes onshore and junk, so get it early.
After that, it’s a long stretch of nothing special. Thursday the 30th through Wednesday the 6th of August is mostly 3 ft to 8 ft of east-northeast short-period swell with fresh cross-off winds 18-25 mph. Energy stays moderate to strong – 641 up to 1501 – but 7-8 second period won’t hold up well on a reef. On Saturday the 2nd of August, period jumps to 16 seconds with 4 ft from the east, energy at 1501, but wind is still cross-off at 18 mph. Clean but not glassy.
Into the second week, it fades. By August 7th and 8th, swell is down to 2 ft to 3 ft with very long 18-20 second periods from the south-southwest, but wind turns onshore with rain and storms, so it’s a washout.
The one true standout is Wednesday morning, July 29th. Glassy, long-period groundswell, clean reef. Crowds are often at Number Threes, but with that early glass and small size, you might get lucky with a few waves to yourself if you’re first in.

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.
