Margaret River Mouth Surf Forecast and Surf Report

G’day, Rusty here. Things are looking a bit tricky for the Margaret River Mouth over the next couple of weeks. We’ve got some solid swell but the wind is gonna be a pest for most of it. The water is sitting at 67°F, which is a touch warmer than usual for this time of year.

The first real window of decent surf kicks off Tuesday morning, the 14th of July. It’s a clean 5ft of SW groundswell rolling in with a long 15-second period, meaning proper lines and decent energy (1034). The breeze is light from the NNE, so it’s a cross-off wind, keeping things tidy. This is a beginner-friendly spot, so it’s not huge, and the waves should be clean and fun. It’s a sheltered river mouth, so it handles the size well. Tuesday afternoon holds up pretty similar, but the period drops a touch.

Wednesday the 15th is a write-off. A strong 22 mph NNE breeze is gonna kill the quality, even though there’s a long-period 17-second swell (1189). It’s just too messy.

Thursday the 16th is a bit of a mixed bag. The morning has some moderate rain and a WSW wind, making it questionable. But the afternoon looks like a real gem. The wind goes glassy, almost dead calm, and we’ve got 5ft of WSW swell (837). That’s your best bet for a clean, smooth session in the first week. That glassy wind is a huge plus.

Friday the 17th through to the end of the first week is a mess. onshore winds and rough conditions. The weekend of the 18th and 19th is a no-go. Saturday the 18th sees a big 10ft WSW swell (2897) but with a howling 25 mph onshore wind, it’s just a washing machine. That’s way too big for beginners and even for most, it’s a paddle-out nightmare.

The second week kicks off with a bit of a lull, but it’s still windy and messy. Monday the 20th and Tuesday the 21st are poor, with strong cross-onshore winds. Wednesday the 22nd through Friday the 24th is more of the same, with only a marginal chance on Friday the 24th morning. That morning sees a 7ft W swell (1332) with a clean cross-off breeze from the NNE, but the conditions are still questionable. It’s better than the rest, but not a standout.

The real standout, and the one to circle on the calendar, is Wednesday the 29th of July. The morning has 7ft of SW groundswell (2568) with a 16-second period, and a light NE offshore breeze keeping it clean. The afternoon is even better: 8ft of SW groundswell (2766) with a 17-second period and glassy, dead calm conditions. This is proper, powerful, long-period swell. It’s a bit much for beginners, but for experienced surfers, this is the best on offer in the entire 16 days. The river mouth will be handling that size well with the right wind. Just be aware that with a long period like 17 seconds, the sets can be a bit gappy at a beach setup, but it’s a river mouth, so it should be fine.

Crowds are possible here, so get in early for that Wednesday session.
