The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got one spot on the radar for the next 16 days: Airport Lefts. This reef break is your only option, and it’s inconsistent, so don’t expect it to be firing every day. The water temp is about average for this time of year, so nothing weird going on there.
The first real action kicks off Friday, September 4th, with swell coming from the SW at 5ft. The period is a decent 14 seconds, so there’s some groundswell energy in the water, but the combined energy is moderate (742). The wind is cross-off from the SE at 16 mph, which will keep things clean but a bit bumpy. It’s marginal, so don’t expect perfection.
Saturday, September 5th, the swell bumps up to 7ft from the SSW, with a longer 16-second period. The combined energy jumps to 2022, which is solid. Wind stays cross-off from the SE at 12 mph. Still marginal, but the size is picking up.
Sunday, September 6th, is the biggest of the early run. Swell hits 7ft from the SSW, with a 17-second period and combined energy of 3127. That’s a lot of power. Wind is cross-off from the SE at 16 mph. This is getting into expert-only territory – over 8ft would be a hard no for beginners, but this is still in the “strong” zone. It’s still rated marginal, so don’t get too excited.
Monday, September 7th, sees a drop to 6ft, but the period stays at 14 seconds. Combined energy is 1631. Wind is cross-off from the SSE at 12 mph. Still marginal.
Now, here’s where it gets interesting. Tuesday, September 8th, the conditions improve. The swell is 5ft from the SSW, but the period is a long 19 seconds, giving it a combined energy of 2859. The wind drops to a gentle 9 mph cross-off from the SSE. The call is “excellent surf conditions for experienced surfers.” This is a standout morning. The long period means it’ll have shape and power, but at a reef break like Airport Lefts, it’ll line up nicely. Crowds are possible, so get there early.
Wednesday, September 9th, keeps the energy going. Morning swell is 8ft from the SSW, 16-second period, combined energy 2859. That’s big, so only for experts. Wind is light cross-off at 9 mph. The afternoon drops to 7ft, still excellent. This is another strong day.
Thursday, September 10th, holds at 7ft from the SSW, 17-second period, 2293 energy. Wind is light cross-off at 9 mph. Another excellent morning. The afternoon is similar.
Friday, September 11th, through Saturday, September 12th, the swell drops to 6ft and then 5ft, with periods around 15-16 seconds. Wind stays light cross-off at 9 mph. The quality dips to “marginal” by Saturday afternoon, but the mornings are still excellent.
From Sunday, September 13th, onward, the swell hangs around 6ft to 8ft, with periods between 14 and 17 seconds. Wind picks up to 12 mph cross-off from the SE. The quality drops back to “marginal” for the rest of the run, but there’s still surfable energy. Monday, September 14th, and Tuesday, September 15th, have decent 7ft+ swells.
The real standout window is Tuesday, September 8th, through Friday, September 11th. That’s when the wind is lightest, the swell has good period, and the quality is rated excellent. The biggest day is Wednesday, September 9th, with 8ft, but that’s pushing into expert-only. For the best balance of size and conditions, Thursday, September 10th, is your pick – 7ft, 17-second period, light cross-off wind, and clean.
After that, the last week (September 16th to 19th) has some 7ft+ swells, but the wind is a bit stronger and the quality is marginal. Still, there’s always something to ride if you’re keen.
Remember, this break is inconsistent, so when it’s on, it’s on. Don’t sleep on the standouts.
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.

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.
