The Lowdown
Look, I’m gonna be straight with you – this 16-day window for Gantheaume Point (Broome) is about as flat as it gets. There’s no surf worth paddling out for. The whole stretch is a write-off.
The swell is tiny, barely a ripple, with heights mostly hanging around 0.3 ft to 2 ft and weak energy readings (mostly single or low double digits – the highest I see is 79 on the afternoon of the 31st of August, and even that’s barely a pulse). The period is all over the place, sometimes a short 3 seconds, sometimes a long 15-16 seconds, but with no size to back it up, it’s just a tease. Winds are mostly cross-on or cross-off, and on the rare occasions they go offshore, it’s for waves that don’t exist.
The water temperature is about 73°F, which is a bit colder than normal for this time of year – about 3° cooler. Not a massive shock, but you’ll feel it if you’re out there waiting for something that never comes.
This break rarely breaks, and this forecast proves it. There’s nothing to get excited about. Even the 31st of August shows a bit of energy (79) from a WSW swell pushing 1.0 ft with a 20-second period, but at that size, it’s still a flat day. The offshore winds on the 31st morning (ESE at 19 mph) would clean it up, but there’s no wave to clean.
If you’re a kite surfer, the windier afternoons – like the 25th of August with a 19 mph ESE breeze – might offer something, but for a surfboard, this is a blank run. It’s not unusual for this area. Sometimes the ocean just doesn’t deliver.
