The Lowdown
G’day, Rusty here. I’ve gone over the local forecast, and honestly, it’s a flat spell for the next 16 days. There’s no real surf to get excited about, and the charts show a long, quiet run with no standout sessions on offer.
The only spot on the map is Gantheaume Point (Broome). It’s a beach and point setup that rarely breaks, so this kind of blank run is pretty normal for the area. The water’s sitting at a touch warmer than usual for this time of year at 80°, so if you’re just having a swim, it’s nice, but don’t bring a board expecting much.
The entire forecast period from Tuesday 15th September right through to Wednesday 30th September is dominated by tiny swell – mostly 0.3 ft to 2 ft – with the combined wave energy barely registering, often sitting between 0 and 15 (weak). The swell direction is consistently from the west or west-northwest, but the period is either short (2-6 seconds) or very long (up to 17 seconds) without any consistency to build proper waves.
Wind is a problem most days too. It’s mostly a cross-onshore breeze from the west or west-northwest around 9 to 16 mph, which keeps the surface choppy. A few mornings, like Thursday 17th and Friday 18th, see cleaner conditions with light cross-offshore or light breezes, but there’s still no swell to make it worthwhile. On Wednesday 16th morning there’s a brief window of glassy conditions with a southerly breeze at 3 mph, but the swell is only 1.0 ft with a weak energy reading of 9 – not enough to ride.
Even the longest-period groundswell days, like Thursday 17th morning with a 14-second period, or Sunday 20th morning with 15 seconds, only produce 0.3 ft to 1 ft of swell. That kind of energy is too small to wrap in properly, and the wind on those days is either cross-offshore or light cross-on, but the size just isn’t there.
Look, sometimes it’s poor for a while and then it changes, but with only one break in the region and it barely ever breaking anyway, this 16-day outlook is a write-off for surfing. If you’re a kitesurfer, the afternoon cross-onshore breezes might be interesting, but for a paddle surfer, leave the board in the shed.
Rusty.
