Table - best surf conditions forecast for Margaret River Mouth over the next 16 days.
Alright, this is Rusty, and I'm looking straight at the Margaret River Mouth (Margaret-River-Mouth). Let's get into it.
First up, the water this weekend is a touch warmer than normal for July, sitting at 67°, with an anomaly of 2° warmer, so it's a bit more pleasant if you're braving the rubber.
The next week or so is gonna be a real mixed bag, and honestly, the first half of this outlook is a tough read for us paddle surfers. The good news doesn't really start kicking in until next Tuesday.
Right now, over this Saturday and Sunday, we've got a solid SW groundswell running, with the period hitting 13-14 seconds. The energy is moderate to strong. The problem is the wind. It's a cross or cross-onshore breeze at 6-12 mph, which is putting a chop on the surface. The waves are 5-5 ft, but the wind is making it marginal at best. If you're a beginner, the size is okay, but the wind chop will make it a frustrating paddle.
Monday the 13th picks up a touch, with the swell nudging 6 ft and a period of 16 seconds. That's a nice, long-period groundswell that will wrap in. But again, the breeze is cross-onshore, keeping it fairly choppy. You'll see the lines, but the surface will be bumpy.
Then, hold onto your hats. Tuesday the 14th is the standout for the first week. The wind flips to a glassy offshore in the morning, with a NNE breeze at only 3 mph, turning to glass in the afternoon. The swell holds at a clean 5 ft from the SW with a 15-second period. This is the one to wait for. The conditions are described as "clean" and "glassy", which for a river mouth spot is perfect. It'll be a much more enjoyable session.
After that, it goes pear-shaped again. From Wednesday the 15th right through to the 17th, the wind screams in from the NNW at 19-28 mph, with rain showers. The swell drops, the surface gets churned up, and the break turns into a messy, lumpy mess. Not for surfing, honestly looks like a kite-surfing setup if you're into that, but for a paddle surfer, it's a hard pass.
The following Saturday the 18th sees a massive spike in energy, with 10 ft swell from the WSW and a 17-second period. That is a huge, powerful groundswell. But it comes with a near-gale onshore wind, making it unsurfable and dangerous. Only for the most kamikaze big-wave chargers, and even then, the wind will ruin it.
Looking into the second week, Sunday the 19th and Monday the 20th calm down with the swell dropping to 6-5 ft and lighter S/WSW winds. It's marginal, but you could get a session in with some patience.
The next true standout targets are Tuesday the 21st and then Sunday the 26th. Tuesday the 21st promises glassy conditions again early, with a NNW breeze at 3 mph and a 5 ft SW groundswell. It should be clean. For the weekend after, Sunday the 26th has a cross-off SSE breeze at 12 mph, with a 4 ft, 16-second SW swell. The forecast says "clean" and good, so that's another one to pin a date on for next week.
Overall, the first few days are a fight against the wind. The best bet this week is Tuesday. For the longer range, keep an eye on the 21st and especially the 26th. It looks like the surf will eventually come good, but you've gotta pick your windows.
Rusty.
