The Lowdown
Alright, Rusty here. Let's be straight with you – this stretch at Whitesand Bay is a tough one. We're looking at a long run of poor surf from now through mid-September, with just one very brief window of hope right at the very end. The water is sitting around 63°F, which is a touch warmer than usual for the season.
Starting off, Friday the 28th of August into the weekend, we've got a weak, short-period swell, barely pushing 4ft from the SW with a lumpy 6-second period. Wind is messy – onshore and cross-on – no clean lines at all. Energy is low.
Saturday the 29th adds a bit of size to 5-5ft, but the period is still short (6-8 seconds) and the wind stays choppy. Not worth the effort.
Sunday the 30th, the wind goes south, and we get a moderate pulse of energy. Swell hits 6ft from the SW with 8-9 second periods, but the wind is cross and fresh, creating lumpy, bumpy conditions.
Monday the 31st is the biggest early on – 7ft from the WSW with 9-second periods and serious energy. But with a fresh cross-onshore wind, it's gonna be blown-out and lumpy. That's expert-only size with no quality.
From Tuesday the 1st of September, it's a slow fade. Swell drops to 3ft – tiny, no energy, wrong wind. There's a bump on Wednesday the 2nd in the arvo (6ft, 6-second period), but the wind is a strong cross-shore, making a mess. Thursday the 3rd is the same story – 6ft, bumpy and onshore.
The entire first week of September is a write-off. Saturday the 5th offers a tiny 3ft wave with a light cross-shore wind, but it's weak and short period. You could splash around on a soft-top, that's it.
Then, right at the end, we have one day. Saturday the 12th of September – the arvo session. Swell jumps to a solid 7ft from the WSW with a short 7-second period. The energy is strong (613). The wind is light and cross-shore from the NNW – that's a huge plus. It's called "marginal" but with clean, light-cross conditions and that size, it's the only game in town. It's short period, so it'll be fat and dumpy on the banks, but for a bigger board and a keen surfer, it could be a fun hour. Beginners should give it a miss.
The rest of the 16 days is a long, poor block with no signs of life. That Saturday arvo is your only hope. For this area, it's a rough run, but it won't stay this way forever.
