The Lowdown
G'day, Rusty here. Gotta be straight with you – this stretch from now through the end of September is a tough one for the Broome area. We're looking at a long, quiet patch with no real surf on offer for the entire 16-day outlook. The only named spot in the mix is Gantheaume Point, and it’s a real frustrating one because it rarely breaks as it is, and when it does, the conditions are just not cooperating.
The pattern is pretty consistent, and not in a good way. From Friday the 11th of September right through to Saturday the 26th, we're dealing with tiny, weak swells. Most days the swell is barely a ripple, with heights hovering from 0.3 ft to 2 ft. The wind is almost always a cross-onshore, and it’s got some chop on it, so the surface is messy. Even when there's a bit of a longer period swell around – like a 15-second groundswell on Friday morning the 11th – the energy is super low, coming in at a weak 4 (combined energy of all swells directed here: 4). That kind of swell just doesn't have the grunt to do anything against the wind.
There’s no standout day. Honestly, there’s no second option either. Every single session is marked as poor surf conditions.
Let’s walk through it. The opening Friday and Saturday are all cross-onshore wind with choppy, bumpy surf. Sunday and Monday are much the same story: moderate breeze, messy lines, and minimal wave height. The 17th of September gives us a hint of cleaner conditions with a cross-offshore wind in the morning, but the swell is still a pathetic 0.3 ft – you'd be floating, not surfing. The afternoon turns onshore and strong at 15 mph, so that's a write-off too.
From there it’s just a rinse-and-repeat of gentle cross-onshore breezes and tiny surf. The 25th of September afternoon sees a fresh breeze at 19 mph pushing lumpy, cross-onshore junk, and the swell is only 2 ft. It looks more like a day for kite surfing than paddling, to be honest.
For the one break we’ve got, Gantheaume Point – it's a beach and point setup that’s exposed to the WNW. It's rarely breaking, and with this outlook, it’s staying that way. Water temps are sitting around 78°F, which is a touch warmer than normal for this time of year, so the ocean feels nice, but the waves just aren’t there.
This is one of those blank runs that’s more normal for the area. It tends not to stay poor for long, but for now, forecasts can change, and we need a serious change in wind and swell direction to see anything rideable.
Rusty.
