The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Broome. To be straight with you – this is a dry spell. There is nothing in the 16-day window that I’d paddle out for. Gantheaume Point (Broome) is the only spot on the cards, and it’s a heartbreaking run of tiny, weak swells and messy wind.
The first possible surf shows on Thursday 20 August but don’t get excited. We’ve got a tiny 0.3ft swell from the west, with a super long 15-second period, light cross-on breeze. It’s small and gutless – combined energy of all swells directed here is only 5 (weak energy). The water’s sitting at 73°, which is a bit colder than normal for this time of year, so bring a thicker suit if you’re stubborn. Friday 21 August and Saturday 22 August are more of the same: 0.3ft to 2ft, choppy cross-onshore winds. The swell period drops to 3 seconds on the afternoons – that’s wind slop, not surf.
The whole first week is a write-off. Sunday 23 to Thursday 27 August offers nothing above 2ft, with onshore or cross-onshore winds and combined energy values stuck between 2 and 6 (weak). It’s flat or junk.
We finally get a glassy moment on Friday 28 August morning – dead calm, 0.3ft west swell with a 16-second period. Clean as a mirror, but there’s almost no wave face. Combined energy is 9 (weak). You could sit on a longboard and hope. Saturday 29 August morning sees a clean 0.3ft west swell with 14-second period and light cross-offshore wind, but same story – no push.
The second week doesn’t rescue us. Monday 31 August morning offers the biggest period of the whole run: 0.3ft from the west at 21 seconds, combined energy 13 (still weak). That’s a groundswell, but it’s so tiny it’s barely a ripple. Clean conditions with light offshore wind though. Tuesday 1 September to Friday 4 September stays flat: 0.3ft to 1ft, with clean mornings but onshore afternoons.
Look, Gantheaume Point “rarely breaks” even on a good day, and this stretch is a total blank. There are 16 straight days with no surf worth recommending. It’s one of those runs where the region just goes quiet. Forecasts can change, but right now, forget the board. If you’re desperate for wave action, the beach-and-point setup here with these tiny chop conditions might be more interesting for a kite than a paddle.
Stay patient.
Rusty.
