The Lowdown
G’day, Rusty here. Let’s be straight with each other – this outlook for Gantheaume Point (Broome) is a tough one. We’re looking at a 16-day window starting from Sunday 16 August, and honestly, there’s not a single slot where the stars line up for a decent paddle. Every single entry comes back with “poor surf conditions,” and the scores reflect that. We’ve got a long, quiet run ahead.
The first recommendation doesn’t even appear – the whole period is a gap. From Sunday 16 August all the way through to Monday 31 August, there’s nothing I’d point you towards. This isn’t one of those areas where it stays flat for long and then fires; this is a place where a blank run like this is more normal. The swell is tiny – mostly 0.3 ft to 2 ft – with weak wave energy. The highest combined swell energy we see is just 13 (on Monday 31 August morning), and even that’s a whisper. The swell direction is mostly WSW or W, which is off the optimum WNW direction for this spot, so it’s not even wrapping in well.
The wind is the real killer. It’s almost always cross-onshore or cross, from moderate to fresh breezes, chewing up what little bump there is. There’s one moment on Saturday 22 August morning when it goes glassy – 3 mph from the WNW – but with 0.3 ft of swell at 15 seconds period, it’s barely a ripple. That long period (over 15 seconds) suggests groundswell, but at this size, it’s not doing anything. The water temp is 73°F with a -3° anomaly, so a bit colder than normal for this time of year. On that glassy morning, it might be worth a float if you’re desperate, but don’t expect a wave you can ride.
Given the constant small messy surf and strong onshore winds, this setup looks more interesting for kite surfing than paddle surfing. There’s just no power or shape for a board. Keep an eye on the long-range stuff – Monday 31 August has a tiny 0.3 ft, 19-second period swell with 13 energy, but with 3 mph cross-onshore winds, it’s still not doing anything. I’d say sit this one out, or go chase another break. The forecasts can change, but right now, it’s a flat spell.
Rusty.
