Table - best surf conditions forecast for Margaret River Mouth over the next 16 days.
G'day, it's Rusty. Let's talk about what we're seeing for the Margaret River Mouth. This sheltered river-mouth setup needs a good alignment of swell and wind, and the water temp is nothing out of the ordinary for now.
The next few days are a mixed bag. The absolute pick of the bunch is Sunday morning (12th July). We've got a 5ft swell running out of the southwest, and the wind is going glassy – totally dead calm. That’s the recipe for a perfect, smooth wave. The combined energy is pumping at 1106, so there's plenty of juice, and with that long period, you'll get proper groundswell lines with big lulls to make the paddle easy. It's a beginner-friendly break, so expect a few other folks wanting a slice of that.
Before that, Wednesday afternoon (8th July) is a solid call. The swell is 6ft from the WSW, with a long 15 second period, and a light offshore NNE wind will keep the faces clean. The energy is huge at 1431, so for a sheltered spot, it's going to be running hard.
The Monday morning (13th July) is also worth a look with 6ft of SW swell and big energy (1532), but the cross-off wind will put a little bit of a breeze on the surface. It's still rideable, just not a glassy finish.
Now, after that first week, things get pretty ugly from the 15th through the 20th. We're looking at strong winds and messy, oversized swell. That Saturday (18th July) pumps up to 10ft from the WSW, which is way too much for this spot, and with the wind howling, you’d be better off rigging a kite than a surfboard.
The last few days of the outlook bring some hope. The Wednesday morning (22nd July) looks good with a clean 4ft SW groundswell and a sweet offshore breeze from the east. The energy is moderate at 734, but that offshore wind will make the waves look beautiful. The Thursday morning (23rd July) is much the same with 4ft and clean conditions. Those are a bit far out to guarantee, but they're the light at the end of the tunnel.
Bottom line: If you can, get out for that glassy Sunday morning. The rest is a bit of a gamble until we get that cleaner window the following Wednesday.
Rusty.
