The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. The only spot with any sort of read on the charts is Gantheaume Point (Broome), but even then, it’s a tough watch. This place is a beach and point set-up that rarely breaks, so when it’s flat, it’s just flat. And for the next 16 days, it’s mostly just that.
The water’s sitting at a touch warmer than normal for this time of year, about 79°F, with a 3°F anomaly, so it’s pleasant enough for a swim, just not for surfing.
We start with Friday afternoon the 11th – tiny 2 ft of windswell from the W, a weak period of 3 seconds and a combined energy of just 5. The wind is a cross-onshore 16 mph from the W, making for choppy, poor conditions. Not worth getting wet for.
Saturday the 12th is a write-off. Morning has a 0.3 ft swell with a long 14-second period, but cross-shore winds at 12 mph make it lumpy. The afternoon picks up a tiny bit to 2 ft from the WSW, but period drops to 4 seconds, and a fresh 19 mph cross-on wind just makes it a mess.
Sunday the 13th is more of the same. Morning has 1 ft at 17 seconds (that long-period groundswell), which might sound interesting, but with a cross-on 12 mph wind, it’s choppy. The combined energy is 94, which is still weak. Afternoon goes back to 2 ft and 3 seconds – garbage.
Monday the 14th through to Thursday the 17th is a flat, choppy wasteland. Swells barely reach 2 ft, periods are all over the shop from 2 to 14 seconds, but the wind is always cross or cross-on. There’s a brief moment Thursday morning the 17th with a clean cross-offshore breeze from the ENE at 19 mph, but the swell is a pathetic 0.3 ft – clean but unrideable.
From Friday the 18th all the way through to Saturday the 26th of September, the pattern doesn’t change. Tiny 0.3 ft to 2 ft swells, short periods mostly, and a constant cross-on wind. The combined energy rarely gets above 10, so it’s basically flat. There’s a few moments of glassy or clean conditions, but with no swell to push, it’s just a lake.
Honestly, there are no standouts here. If you’re desperate, the cleanest window is Thursday morning the 17th with that offshore wind, but you’d need a wave to ride. This is a blank run for the area, and it’s just one of those stretches where the forecasts are what they are. Might be more interesting for a kite surfer than a paddle surfer, but even then, the wind’s not consistent enough.
Stay patient, mate. It tends not to stay this poor for long.
Rusty.
