The Lowdown

G’day, it’s Rusty here, and I’ve had a good look at what’s comin’ for Little Austi and Main Beach. Straight up, we’ve got a bit of a flat spell to start, so don’t rush to wax up just yet.

The first few days are a write-off, sorry. From Tuesday the 28th through to Friday the 31st of July, we’re lookin’ at tiny, weak dribble – swell heights barely 0.3 ft to 1 ft, with periods all over the place and poor conditions. The wind’s mostly cross-off or cross-on, but there’s just no energy to work with. The combined swell energy is well under 100 (like 9, 15, 4, 7), so it’s a total snooze fest. Saturday the 1st of August stays poor through the morning, but the afternoon brings a little pulse – 4 ft from the SSE, 9 seconds, with a combined energy of 315 (moderate). Wind’s light cross-on, but with rain showers, it’s still only marginal. The water temp is 65°F here, which is about 2°F warmer than average for this time of year – nothin’ wild, just a touch on the mild side.

Now, Sunday the 2nd of August is where it gets interesting. That’s our first true standout. We’ve got a solid 6 ft SSE groundswell in the morning, comin’ in at 13 seconds – that’s proper long-period energy – and the combined swell energy jumps to 967 (strong). The wind is offshore from the NNW at 6 mph, so it’s gonna be clean as a whistle. The afternoon holds up with 5 ft, 12 seconds, and a cross-off breeze from the WSW at 9 mph. This is a beach and reef setup, so that long-period swell might break a bit straight on the beach, but the reef sections could really shine. Wave height is over 5 ft, so it’s not for beginners, but intermediate surfers should have a blast. The crowd here is “sometimes” – you might find a few out, but it’s worth it.

Monday the 3rd of August turns ugly again – the wind swings strong cross-on from the SSW at 19 mph, and the swell drops to 3 ft but gets all chopped up. Not worth it. The rest of that week stays average with onshore winds and lumpy conditions, even though there’s a big spike in swell size on the 5th and 6th of August – 10 ft and 8 ft from the SSE. Those are expert-only waves, but the wind is cross-on and strong, so it’s messy and honestly more for kite surfers than paddle. The combined energy hits 1381 (very strong) on the 5th, but it’s just not clean.

Friday the 7th of August is another standout. We get 6 ft from the SE, 8 seconds, with glassy conditions – wind is nearly dead from the SW at 3 mph. The water goes glassy, and the combined energy is 490 (moderate). This is a solid, fun size for a beach and reef, but the period is short (under 8 seconds), so the waves might be a bit lumpy and close together. It’s clean, though, so get out there early. The next day, Saturday the 8th, has a morning window with offshore NNW wind at 6 mph and 4 ft from the ENE, 8 seconds, but the afternoon gets cross-shore and messy.

Looking further out, the second week has some promising calls. On Monday the 10th of August, we’ve got offshore NW wind at 3 mph with 4 ft ENE swell, 10 seconds, and combined energy of 394 (moderate). Clean and fun. Then Tuesday the 11th of August looks like a real belter – 7 ft from the ENE, 11 seconds in the morning, with north-northwest offshore wind at 3 mph. Combined energy hits 959 (strong). That’s solid, clean, and the swell direction matches the optimum ENE. The afternoon pushes 7 ft at 12 seconds, but the wind turns cross, so morning is the pick. Wednesday the 12th of August holds up with 5 ft, 12 seconds, and offshore NNW wind – another clean session with combined energy of 683 (strong). This is a long-period groundswell, so it’ll be better on the reef sections than the beach.

Overall, the best on offer is Sunday the 2nd of August and Tuesday the 11th of August. Both have solid swell, good wind, and strong energy. The rest of the run has some windows, but those two are the standouts. Don’t hold your breath for the first week – it’s a slow start, but it builds nicely.

Rusty.
