The Lowdown
G’day, Rusty here. Look, I’ve scanned the charts and the outlook for the next 16 days, and I’ll be straight with you – we’ve got nothing to get excited about. The only option on the table is Gantheaume Point (Broome), and it’s a tough sell. This spot is a beach and point set-up that’s classed as “rarely breaks,” so it’s not exactly reliable at the best of times, and this forecast is a real dud.
The water temp is sitting at 79°, which is a touch warmer than normal for this time of year – nice for a swim, but it won’t help the waves.
Right now, starting from Sunday the 13th, and stretching all the way through Monday the 28th of September, every single session is rated as “poor surf conditions.” We’re talking tiny swell heights, mostly between 0.3 ft and 2 ft, and the combined energy of all swells directed here is weak, with values scraping in under 100 (a measly 100 at best on Sunday morning, but mostly in the single digits or low teens). The swell direction is mainly from the W or WSW, but with period readings all over the shop – some long-period groundswell lines up to 17 seconds on the 13th, but with wave height at just 1 ft, it’s practically flat.
Wind is our big problem. Nearly every session is cross-on, choppy, and messy. There are a couple of glimmers – like Wednesday morning the 16th with glassy conditions, and Thursday morning the 17th with clean cross-offshore winds out of the east at 19 mph – but even then the swell is only 0.3 ft to 0.7 ft. There’s nothing to ride.
Given the weak energy and the fact it’s a beach-and-point break, this setup looks more suited to a kite surfer on a gusty afternoon than anyone trying to paddle. Honestly, if you’ve got a board, save the wax. This is a blank run, and for an area where this spot rarely breaks, a quiet spell is pretty normal. Forecasts can change, but for now, we wait.
Rusty.
