The Lowdown
G'day, Rusty here. Let's get into it.
We've got a solid run of surf coming up at Airport Lefts. This exposed reef break handles the SW swell well, and we've got a good, consistent supply of it through the whole outlook.
The water is sitting at 79° right now, which is pretty much what you'd expect for this time of year.
The first couple of days are on the table, but they're not the pick. Sunday the 13th has chest to head high swell around 6ft from the SW, but that cross-off breeze at 16 mph is a bit lumpy. The wave energy is strong, sitting at 2512, but the quality is average. Monday the 14th is similar, with a bit less size.
Tuesday the 15th morning is where it starts to clean up. The wind turns offshore from the ESE at 12 mph, and we've got 6ft of SW swell with a 15-second period. That long period means proper groundswell energy, so the waves will have some push to them. The energy is still high at 1455. This is a standout window, especially for a Tuesday morning.
The surf hangs around for the rest of the week, but it’s the following weekend that gets exciting. Saturday the 19th has lighter winds, but Sunday the 20th morning is a real highlight. We’re looking at 6ft of SW swell with a 16-second period and a gentle breeze from the SE. The energy is pumping at 1852. It’s a reef break, so that long period should wrap in nicely. Be aware, crowds are possible here, so you'll want to be early.
Then the real standout of the whole run lands on Friday the 25th. We've got 8ft of SSW swell with an 18-second period. That is a very long period groundswell. The energy is massive at 4391, which is very strong. The wind is a light SSE breeze at 6 mph, practically glassy. This is expert territory at over 8ft, so only the experienced crew should be out. For the rest of us, it's a great show. The following days still have plenty of size but the period drops back.
There’s a few gaps where the quality dips, like on the 18th and 22nd, but the swell never fully disappears. All in all, there’s something for most of the 16 days, with a couple of absolute crackers.
Rusty.
