The Lowdown
G’day, Rusty here. Let’s be straight up – it’s a quiet stretch ahead for Gantheaume Point (Broome). We’ve got a 16-day window, and honestly, there isn’t a single day where the surf is worth paddling out for. The whole run is filled with poor surf conditions, tiny waves, and messy wind. The first few days are particularly flat, with swell heights barely scraping 2 ft and a weak combined energy reading (6) on the afternoon of the 30th. That’s just not enough to work with.
Through the first week, from the 30th of August right through to the 6th of September, we see a mix of cross-onshore and onshore winds, with speeds often in the 12 to 19 mph range. That’s going to chop things up badly. Swell hangs around 0.7 ft to 3 ft, with periods mostly short – 3 to 6 seconds – so no real power behind it. The combined energy stays low, mostly under 30. The water temperature is sitting at about 77°, which is pretty normal for the time of year, about average.
There’s a little shift around the 7th of September, Monday morning, when offshore winds from the southeast kick in at 16 mph, making conditions clean. But the swell is still only 1 ft from the WSW with a period of 7 seconds – too small to bother with. Combined energy is just 11. That pattern of clean but tiny waves sticks around through to the 14th of September, with offshore or cross-offshore winds on many mornings, but swells never break 0.3 ft to 1 ft. Periods do stretch out a bit – up to 19 seconds on the 11th afternoon – but that’s just a long period with no height, so it’s flat lining.
The 14th of September afternoon shows a bit more energy, with a combined energy of 61 from a 1 ft WSW swell at 18 seconds, but it’s cross-onshore and choppy, so still no dice. Honestly, this is a rare-break spot that rarely turns on, and this forecast proves it. If you’re keen on something, the clean offshore mornings around the 8th to the 12th of September offer the best chance for a skimboard or a longboard glide on the tiniest of bumps, but for proper surf, there’s nothing here. For the kite crew, those afternoons with 12 to 19 mph cross-onshore winds and a bit of bump could be more interesting than paddle surfing.
All in all, a blank run. It’s not unusual for this area, but forecasts can change.
Rusty.
