The Lowdown
Alright, let’s switch to feet and Fahrenheit. Rusty here, same story for Little Austi and Main Beach. This is a tough stretch, with a big dry spell from Thursday the 24th of July through the 27th, and then another long flat period up to the start of August. You’ll be waitin’ for waves.
The first real chance is Tuesday afternoon, the 21st of July. We’ve got a 4ft swell from the ENE, 10-second period, moderate energy (328). Water temp’s about 65°, which is normal for this time of year. Wind’s NE at 15 km/h, a cross-off, so it’s clean but marginal. Surfable, but nothin’ special.
The standout is Wednesday the 22nd of July. Both sessions have 4ft of ENE swell, same 10-second period, and light wind from the W and WSW at just 5 km/h. That’s cross-off and clean, with energy at 238 and 231. It’s the day to go. The break is fairly consistent, so waves will come, and crowds are possible.
Thursday the 23rd drops fast – 3ft down to 3ft, with strong cross-off winds up to 25 km/h, energy down to 143 and 97. Poor. Then from Friday the 24th through Sunday the 27th, it’s flat to tiny – 1ft down to 0.3ft, energy in the teens. Not worth it.
Monday the 27th of July brings a new SSE pulse – 3ft, 8-second period (118 energy), with a light offshore NNW wind in the mornin’. Clean but ordinary. The arvo has a cross-shore and 133 energy, but still poor quality.
Tuesday the 28th is glassy with no wind, but the swell is a tiny 0.7ft from the SSE, 15-second period (21 energy). Long-period groundswell, but no size. Skip it.
Wednesday the 29th has a 3ft swell from the SSW in the mornin’, short 5-second period (69 energy), glassy from a light NNW wind. Surfable but ordinary. The arvo’s a waste.
From Thursday the 30th of July through the 2nd of August, it’s mostly flat or tiny – 0.3ft to 1ft, with onshore winds. Energy in the 0 to 61 range. No good.
The next real hope is Monday the 3rd of August. Mornin’ has 3ft from the SSE, 10-second period (194 energy), with a light NNW cross-off wind. Clean and surfable but ordinary. The arvo gets 4ft SSE swell (261 energy), but a 20 km/h cross-shore from the NE messes it up.
The second-week standout is Tuesday the 4th of August. Both sessions have 3ft to 3ft of SSE swell, 10-second period, with an offshore wind from the NNW at 15-20 km/h. Energy is 213 and 235. Clean, offshore, and consistent. That’s your window. Crowds are possible.
Wednesday the 5th of August fades with 3ft SSE swell (178 energy), but a strong 25 km/h cross-off wind from the W. Clean but ordinary.
Bottom line: The 22nd of July is your best early option – clean, fun, small. Then wait all the way to the 4th of August for the next decent day. Long gaps, but this spot can turn around, so keep watchin’.
Rusty.
