Mewslade Bay Surf Forecast and Surf Report

Alright, mates, Rusty here. Let’s talk about what’s cookin’ at Mewslade Bay over the next sixteen days. It’s a bit of a rollercoaster, with a whole lot of blown-out slop, but there are a couple of clean windows that will have you frothing.

The first day, Thursday the 10th, is a total loss. Screaming onshore winds and dirty surf. Just stay on the beach.

Now, Friday the 11th morning is your golden ticket. The sky clears, the wind goes offshore from the northwest, and the ocean glassed right up. You’re looking at a clean 4ft swell from the WSW with a 9-second period, giving those waves some shape and punch. The combined swell energy is a solid 266, so there's plenty of power. Mewslade Bay is an exposed SW spot, so it’ll be handling that swell perfectly. It’s a fairly reliable break, good for the intermediates, though you might see a few other heads in the water as crowds are possible here.

Then the wheels fall off. Saturday is a messy, short-period 5ft swell hammered by onshore wind. Sunday the 13th morning is a nice surprise, though – clear skies, clean conditions, and a nice 4ft groundswell from the west reading 443 energy. That’s got some grunt. The 10-second period will help the waves hold their shape, and the cross-off wind will keep the surface tidy.

After that, from the 14th right through to the 19th, it’s a frustrating run of tiny, wind-affected surf. A proper lull. The swell drops off to barely a ripple in some sessions.

Then, looking way out to the 20th of September, there’s a late pulse. Sunday the 20th morning shows a punchy 7ft swell from the WNW with 394 energy. But the period is a short 6 seconds, so it’s going to be a lumpy, jumbled mess. The wind is cross-off from the north, so the surface will be clean, but the waves themselves will be poor quality – peaky, choppy, and not worth it for a paddle board. If you’re into kite surfing, though, that’s your jam. For us paddlers, it’s a hard pass.

The real standout, the one to circle on your calendar, is that Friday the 11th morning. That’s your clean, offshore, fun-sized session. A few of the other clean mornings (Sunday the 13th, maybe the 16th) are worth a paddling for a quiet one, but the size is smaller and the energy is lower.

The water temp is about average for this time of year, so you can leave the 5/4 at home.

Keep your eye on the clean windows and don’t waste your energy on the trash days.

Rusty.
