Table - best surf conditions forecast for Little Austi and Main Beach over the next 16 days.
Alright folks, Rusty here with a look at what's on the table for our local stretch.
Right off the bat, I gotta be straight with you – we have a run of iffy conditions before we get to anything worth paddling out for. The next week or so is looking pretty average, with a lot of messy, onshore wind and choppy surf. The water's sitting at 65°F which is pretty much what you'd expect for this time of year.
Our first real standout comes on Saturday morning the 11th. That's where things start to look up. We've got a 4ft SE swell rolling in with a clean 9-second period, and the wind is swinging offshore from the NW. The wave energy is a moderate 320, and that offshore wind is going to clean things right up. Little Austi and Main Beach should be offering up some tidy, workable lines. The swell drops off a bit into the afternoon to 3ft, but the period stretches to 11 seconds with that same offshore flow, making it a solid option for a long session.
Honestly, the rest of the first week is more of a waiting game. That Saturday morning window is the one to circle on your calendar. After that, we hit a flat spell from Sunday the 12th through to around the 19th – a long dry stretch with barely any swell and mostly clean but tiny conditions. You'll be looking at ankle-biters at best.
Further out, around Sunday the 19th of July, there's a whisper of a pulse. It's only 2ft from the SE with a very long 12-second period, so it'll have some push. The wind is light offshore from the NW, which will keep the surface clean. The energy is low at 78, so it's not going to be firing, but for a small-wave board, it might scratch an itch. Just don't expect the world – it's a long range call and we've seen these little blips fade before.
So, to sum it up: your best bet is Saturday the 11th. Get in the water while the offshore wind is on it. The rest of the outlook is looking pretty slim, but that's the way it goes sometimes.
Rusty.
