The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next few days are a write-off for Little Austi and Main Beach. We’ve got barely a bump of swell, and the wind is all over the shop. It’s a tough start, but hang in there, because things are gonna change.
The first real glimmer of hope lands on the morning of Saturday, the 1st of August. We get a pulse of 5ft SSE swell with a 10-second period, and the wind goes glassy. That’s clean surf, and the wave energy is moderate (509). The water temperature is running a touch warmer than normal at 66°, about 2° above average for the time of year, so it’s not a shock to the system. This is your best option on offer – a standout window for a beach and reef setup that’s fairly consistent. Expect crowds sometimes.
The swell hangs in there on Sunday morning, the 2nd of August. We’ve got 5ft SE swell, a 12-second period, and a clean cross-offshore breeze. The wave energy is still moderate (557). A solid session to be had, but the Saturday morning glass is the pick.
After that, the swell drops away fast. Monday the 3rd has a small 2ft SE swell with offshore wind, but it’s hard to get excited about it. From Tuesday the 4th right through to Friday the 7th, it’s mostly flat and poor. There’s a real gap in the action.
Then, on Saturday morning, the 8th of August, we get another shout. This one is a late call, so a bit less certain, but it looks promising. A 5ft SE swell with a 13-second period and a light offshore breeze. That’s a groundswell, and the wave energy is strong (943). It’s clean, but remember, long-period swells can make a beach break like this straighten out a bit. Keep an eye on it, but it’s not the crystal-clear call of the 1st.
The rest of the second week fades into smaller, weaker swell with onshore winds. Tuesday the 11th and Wednesday the 12th are just tiny leftovers. There’s a possible pulse on the 13th afternoon with 4ft SE swell, but the wind is messy and it’s a marginal call.
So, the best of the lot is the Saturday morning, 1st of August. That’s the one to circle. The 8th of August is a promising backup, but lock in that first Saturday.
Rusty.
