The Lowdown
G’day, Rusty here. I’ll be straight with ya—this is one of those outlooks where patience is gonna be your best mate. The entire 16-day window for the Broome area is pretty much a flat spell with nothing to get excited about. We’ve got a long stretch of marginal conditions ahead, so let’s break it down.
Right from Friday the 21st of August, it’s a scratchy start. Gantheaume Point (Broome) is showing tiny 0.3ft to 2ft windswell from the W, but the period is short—only 4 seconds on the best of it, and the combined swell energy is a measly 9. The wind is onshore or cross-onshore most of the time, with a moderate breeze offering up choppy, poor surf. Not a single wave worth paddling for.
This flat pattern drags on through the following days. The morning of Tuesday the 25th sees a bit of a shift with a clean look from a cross-offshore ESE breeze at 19 mph, but the swell height is still a pathetic 0.3ft from the W with a longish 14-second period—just not enough push. The water temperature is running about average for this time of year.
It’s not until Tuesday the 1st of September that we get a faint pulse worth mentioning. Tuesday afternoon, Gantheaume Point sees the combined swell energy jump to 66—moderate in the numbers, but still only 1.0ft from the WSW with a very long 18-second period, and the wind goes offshore from the ESE at 12 mph, giving clean conditions. The problem? That swell is too small and too long-period for a beach-and-point setup to shape up proper. You’d be waiting ages between sets for a knee-high lump. Not really surfable.
After that, it’s back to the doldrums for the rest of the run. The whole 16 days is basically a write-off. Gantheaume Point rarely breaks anyway, and this forecast confirms that—if you’re after a paddle, you’re better off finding a pool.
Rusty.
