Margaret River Mouth Surf Forecast and Surf Report

Alright, this is Rusty, checking in with a look at what's coming up for Margaret River Mouth.

Right off the bat, we're looking at a pretty average run of surf for the next couple of weeks. The water temp is sitting at 66°, which is a touch warmer than usual for this time of year, so you might get away with a slightly thinner suit. The wave energy is moderate at best for most of the forecast, with the combined energy reading around 889 (moderate) on Tuesday afternoon, but it's a messy start with a strong cross-onshore wind making things lumpy. There's a big gap in quality surf right at the beginning, so we'll have to wait for conditions to settle.

The best window looks to be Wednesday afternoon, the 26th of August. The swell is a solid 8ft from the WSW, with a very long period of 17 seconds. That's a proper groundswell with serious energy – the combined energy reading is a massive 3643 (strong to very strong). The wind is a clean cross-offshore, so the surface will be looking good. Keep in mind that an 8ft swell with that long period is going to be powerful and definitely one for the experts. The long period can also make it break a bit straight at the beach, but the river mouth setup should handle it.

Thursday the 27th of August holds some decent, clean 7ft SW swell in the morning, but it's blown out by a fresh breeze. The rest of the first week drops off quickly into small, clean but weak surf, with energy readings dropping into the 200s and 300s.

Then, on Saturday the 29th of August, we get a beautiful little window. The afternoon brings a glassy, 5ft SW swell with a 17-second period. The combined energy is 1449 (moderate), and with the wind going glassy, it's the best quality of the whole run. It's not huge, but it will be clean and fun. The next morning, Sunday the 30th, is also worth a look with a light cross-shore wind and 5ft SW swell, though it's a bit more disorganized.

After that, we hit another lull. The middle of the week is small and choppy, with winds mostly onshore or cross-onshore. The next real pulse of interest is on Monday the 7th of September. The morning is a bit iffy with a cross-on wind, but the afternoon shows a clean 7ft SW swell with an 18-second period. The combined energy for that afternoon is 2940 (strong to very strong). Again, this is big, powerful, and long-period, so it's strictly for the experienced crew. It's a bit further out in the forecast, so keep an eye on it, but that one has promise.

Overall, the standout is the glassy Saturday afternoon session, with the Wednesday afternoon being the big, powerful option for the experts.

Rusty, signing off.
