The Lowdown
G’day, Rusty here.
Look, I’m gonna be straight with you. The next couple of weeks are looking pretty grim for a proper paddle. We’ve got a run of small, gutless swell and onshore winds that’ll have the surface all chopped up. The first real window of surfable waves is still a ways off, and even then, it’s not going to be anything to write home about.
The only spot with any sort of forecast in the mix is North Wall Mackay Harbour Beach. Water temp is sitting at 69°, which is about average for this time of year, so no surprises there.
We’re looking at a long, flat spell from now through the weekend of the 16th and 17th. There’s a pulse of energy showing for the 17th, with the swell pushing to 3ft from the ESE, but the wind is going to be howling cross-onshore at 19-22 mph, which will make it messy and lumpy. The combined energy is moderate (118) that afternoon, but the onshores will kill any real quality. This is a beach setup, and with that much wind and chop, it might be more interesting for the kite crew than for us surfers.
The early part of the following week, the 18th and 19th, still shows some swell around the 3ft mark, but again, it’s coming in with a short period (6-7 seconds) and those fresh onshore winds are going to keep it poor. The energy picks up a bit on the 20th, with a combined energy of 176 that morning, but the swell is still small and junky, and the wind is still on it.
Honestly, there’s nothing here that’s a standout. The whole 16-day window is a write-off for quality surf. The swell is always too small, the winds are always wrong, and the periods are short and weak. It’s one of those stretches where the ocean just doesn’t want to cooperate. Forecasts can change, but as it stands, you’re better off finding something else to do for the next couple of weeks.
Stay salty.
