Alright folks, Rusty here. Let’s have a look at what’s coming up for Margaret River Mouth over the next couple of weeks.
We’re in for a bit of a mixed bag. The first few days are pretty rough, with some rain and strong onshore winds, so you won’t want to rush out. The water temp is sitting at 67°, which is right around normal for this time of year, so nothing to worry about there.
The first real chance of a decent wave comes on Monday, July 6th. The swell is building to 6 ft from the WSW, with a clean 15 second period. The wind is offshore out of the SE, so the surface should be clean. The combined energy is moderate (1507), and it’s a consistent river mouth setup, so it’s a good one for the beginners. Monday afternoon holds similar with 7 ft swell and 12 mph offshore breeze – still clean.
Tuesday, July 7th looks like the main standout here. Morning session has 6 ft of SW swell, a 16 second period, and gentle offshore winds from the SE. The water is clean, the energy is solid (1677), and it’s a river mouth, so the long period swell will wrap in nicely. This is the pick of the early run. Tuesday afternoon drops off a bit, but still surfable.
Wednesday, July 8th has a strange one – a 6 ft WSW swell with a 17 second period, but the wind is light and variable, almost glassy. The energy is high (1796), but the tide might be a factor. It’s worth a look if you can time it right.
Then we hit a dry spell. From Thursday, July 9th through to the 12th, the wind turns onshore or cross, the swell drops, and the conditions turn poor. You’ll be scratching your head, not the board.
Into the second week, things get more promising. Tuesday, July 14th has a 5 ft SW swell with light offshore winds from the ENE, clean and glassy in the morning. The energy is moderate (832), and it’s a good beginner wave. Then Wednesday, July 15th is smaller but still clean.
The real late highlight is Sunday, July 19th. The morning brings a 6 ft SW swell, 15 second period, and glassy conditions with a light SW breeze. The combined energy is solid (1262), and the forecast is calling for very good surf. That’s the one to mark on the calendar, but it’s a way off, so keep an eye on it.
Overall, the best of the run is Tuesday, July 7th and Sunday, July 19th. The river mouth handles the long period swell well, so don’t be put off by the 15-17 second intervals. Just be aware that crowds are possible here, especially on the good days.
Rusty.

Information about the Margaret River Mouth Surf forecast
The above surf forecast table for Margaret River Mouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Margaret River Mouth can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Margaret River Mouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
