The Lowdown
G’day, Rusty here.
We’ve got a solid run of surf on the cards at Airport Lefts, a reef setup that’s exposed to the swell. It’s an inconsistent sort of spot, so when it fires, you want to be on it. The water’s sitting at 80°F, which is about average for the time of year.
The pattern kicks off Thursday morning, September 10, with a clean 7ft SSW swell running at 15 seconds. The combined energy is strong at 2368, and while the wind is cross-off from the SE at 9 mph, it’s a risk tstorm morning—keep an eye on the sky. That afternoon clears up, with the same swell size and a 16-second period, still cross-off. Friday morning and afternoon hold 6ft SW groundswell, with a 16-second period and moderate cross-off breeze. The energy stays high, around 1865 to 1819. Saturday, the 12th, sees the swell drop to 5ft then 5ft, with a 14-second period, but the wind stays cross-off and the surf is clean.
Sunday the 13th is a standout: 6ft SW swell in the morning, jumping to 7ft in the afternoon, with a 17-second period and strong energy of 2557 to 2614. The wind is cross-off, and the surf is clean—this is a real highlight for experienced surfers, as the 7ft is getting into expert territory. Monday and Tuesday keep the 6ft to 6ft SW swell going, with consistent cross-off winds and clean conditions, though energy drops a bit to around 1436-1494.
The big one comes on Wednesday, September 16. The morning has a 6ft SSW swell at 15 seconds, but the wind finally turns offshore from the ESE at 12 mph. That’s glassy, clean perfection. The energy is moderate at 1181, but the offshore wind makes it a top call for the period. The rest of the week stays in the 5ft to 6ft range, with cross-off winds and clean surf, but nothing beats that Wednesday morning window.
Now, looking ahead to the second week: Sunday, September 20, is a monster. The morning brings a 10ft SW swell at 16 seconds, with cross-off winds and clean conditions. The energy is huge at 4027. That’s only for experts—over 8ft, you need to know what you’re doing. The afternoon holds 8ft, still cross-off. Monday the 21st eases to 7ft, then the rest of the week settles into a 5ft to 7ft SSW swell, with cross-off winds and clean surf for the most part. The final days, September 24 and 25, offer 6ft to 7ft SSW swell, with some clouds but still cross-off and clean. The 25th has a 20-second period, which is very long, so the waves will have plenty of energy and shape, but at a reef break like Airport Lefts, that’s a good thing.
Crowds are possible here—it’s an inconsistent spot that can get busy when it’s on. The best session is Wednesday morning, September 16, with that offshore wind and clean 6ft swell. The second best is the Sunday the 20th for the big, powerful 10ft swell, but only if you’ve got the skills.
Rusty.

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