The Lowdown
G'day, Rusty here. We've got a stretch of solid groundswell coming through for Airport Lefts, but it's a real mixed bag. The water is sitting at 79°, which is pretty normal for this time of year, so that's fine.
The main story is that while there's plenty of energy in the water, with moderate to strong readings (4140 down to 1037), the wind is a consistent cross-off from the ESE or SE. That keeps things clean, but it's not the glassy offshore we'd all be dreaming of. The biggest issue is that a lot of these sessions are tagged as "marginal" due to swell direction or tide, so don't expect perfection.
The standout period is definitely the 28th of August. We've got a clean 8ft swell from the SSW with a 16-second period, and the light breeze makes for excellent conditions for experienced surfers. The combined energy (2799) is solid. That's the one to circle on the calendar. The 27th of August afternoon also looks interesting with a 3ft swell but a very long 20-second period, which could produce some clean lines on the reef.
The 19th to the 26th of August is a bit of a grind. The swell is there, but it's consistently "marginal" and the wind is a moderate breeze. The 1st of September also sees a return of 8ft swell (3362 combined energy), but it's back to being "marginal" and onshore. The 3rd of September morning has a 5ft swell with a light breeze, but it's a long way out, so keep an eye on that.
Overall, this is a spot for the committed. Airport Lefts is a reef break that's inconsistent, so it's not a place you can just show up. When it's on, it's on, but with the cross-off wind and the "marginal" tags, you'll need to be a bit fussy about when you paddle out. For the less experienced, it's worth noting that the 8ft swell on the 19th is getting too big for beginners, and anything over 8ft on the 1st of September is expert territory.
Stay on it, and check the tides.
Rusty.
