Margaret River Mouth Surf Forecast and Surf Report

G’day, Rusty here. Look, if you’re hanging out for some waves at Margaret River Mouth, you’re going to need some patience. The next couple of days are pretty ordinary, but there’s a little window of hope if you pick your moments.

The water temp is sitting at 67°, which is a touch warmer than usual for this time of year – nice one, not that you’ll be thinking about that with the wind we’ve got.

The pattern for the next 16 days starts off messy. Wednesday arvo and all of Thursday are a write-off with that solid 8ft to 6ft WSW swell getting chopped up by cross-onshore winds. The wave energy is pumping – we’re talking strong to very strong energy (2791 and 1799) – but it’s all rough and unruly. Not worth a paddle.

Then we get a gap. Friday morning, 21st August, is the real standout. The swell drops to a clean 6ft from the SW with a solid 14-second period (that’s groundswell, plenty of push), and the wind goes glassy. The wave energy is still moderate to strong (1362). For a river mouth, that long period groundswell can sometimes make things a bit too straight, but with glassy conditions, this is the best on offer. I’d be there early.

After that, it’s a pretty grim stretch. From Friday arvo through to Monday the 24th, the wind swings around and the swell drops. Saturday and Sunday are particularly nasty with cross-shore breezes and chop. There’s a moderate (976) energy drop on Saturday morning, but it’s not worth it.

Another gap opens up. From the 25th through the 31st of August, the swell stays small or gets messy again. The 26th sees a bump of 8ft WSW swell (strong energy at 2918), but it’s onshore and choppy – more of a kite session than a paddle. The 27th has some clean cross-offshore winds, but the swell is only 4ft to 6ft, and the energy is moderate (1212). It’s surfable, but nothing to get excited about.

Into September, there’s a flicker of hope on Wednesday morning, 2nd September. The swell is 5ft from the WSW with a 13-second period, and the wind is glassy again. The energy is moderate (865). It’s clean, it’s tidy – a solid choice if you’re keen to get wet. Then Thursday morning, 3rd September, has a 6ft WSW swell (moderate energy at 1602) with onshore wind, but it’s light, so it could be okay.

The real takeaway? Friday 21st August morning with glassy conditions is the standout. And Wednesday 2nd September morning is a promising, distant second option. The rest is mostly for the patient or the desperate.

Later, Rusty.
