The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for the next couple of weeks.
The honest truth is, we’re in for a long, flat, and frustrating start. It’s going to be a real struggle to get a wave for the first week and a half, with the surf basically non-existent and the wind mostly messy. You’ll be looking at a lot of small, choppy, or cross-onshore junk until we get a glimmer of hope towards the end of the period. Keep your expectations low.
Let’s break it down day by day. Starting Thursday, the 10th, we’ve got a tiny 1 ft ESE swell at Little Austi and Main Beach, but a cross-on south wind is making it a total mess. The water is sitting at 64°, which is pretty normal for this time of year. Friday and Saturday are even smaller, with a few tiny pulses of ENE swell, but the wind is never quite right. It’s a real bummer, honestly.
We get a little lift on Sunday the 13th. The morning is clean with a cross-offshore breeze, but the swell is only 0.7 ft. The afternoon shapes up a bit better with a 4 ft NE swell, and the wind is still cross-off, keeping it clean. It’s not a standout, but it’s a surfable wave after a long drought. The energy is still weak (75).
Monday the 14th is the first real possibility. The morning sees a 3 ft NNE swell with a clean offshore wind from the NNW. The energy picks up to a moderate 147, and the wave period is a short 6 seconds, so it’ll be a bit weak and lumpy, but it’s the best we’ve seen. The afternoon is bigger at 5 ft NE, but the wind goes cross-off. The conditions are still described as “very ordinary,” but you could get a couple.
Tuesday the 15th is a write-off with onshore winds and a messy 4 ft SSE swell. The rest of the week is tiny and mostly wind-affected. There’s a long gap here with nothing worth paddling out for.
Now, here’s the light at the end of the tunnel. Sunday the 20th is your first real standout. The morning brings a clean 2 ft SSE swell with a light offshore breeze from the north. The energy is solid at 228, and the period is a nice long 14 seconds, so it’s proper groundswell. This is a promising window for a clean, fun session. The afternoon is similar in size but the wind picks up, so aim for the early bird session.
Monday the 21st is a no-go. The swell jumps to 6 ft SSE, but with a strong cross-on south wind, it’s going to be a washing machine. The energy is high (810), but the quality is poor. This setup looks more interesting for kite surfing than paddle surfing.
Tuesday the 22nd is your absolute best bet. The morning is glassy. A 2 ft SSE swell with a 12-second period is rolling in with no wind. That’s as clean as it gets. The energy is moderate (307), and the conditions are described as “good.” This is the one to circle on your calendar. The afternoon jumps to a beefy 7 ft NE swell, but it’s too big for beginners and with onshore wind, it’s only for the experts.
The final few days of the forecast window drop off again with strong onshore winds and small, messy surf. The swell disappears completely by the 25th.
So to sum it up, it’s a long wait for a couple of fleeting windows. The best of the bunch is Tuesday the 22nd morning with glassy conditions and a clean 2 ft SSE groundswell. Sunday the 20th morning is your second-best shot.
Stay patient, and keep an eye on the charts.
Rusty.
