Mewslade Bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what Mewslade Bay has in store for us over the next couple of weeks.

Right off the bat, I’m going to be straight with you – we’ve got a long, frustrating stretch of onshore and cross-shore chop ahead, with a lot of poor conditions. The water temp is about normal for this time of year, nothing crazy. The first window that looks even remotely usable isn’t until the morning of Monday the 21st of September. That’s a solid week of waiting.

Before that, we do see a spike of moderate energy (576) on Saturday the 19th with 7ft swell from the west, but the cross-onshore wind from the WSW is going to mess it up. That one’s a kite-surfing setup if anything. The same goes for Sunday the 20th – a 6ft west swell has cross-onshore wind again, spoiling the shape.

Alright, let’s talk about the proper highlight. The best on offer is Monday the 21st of September. We get a clean 6ft west swell rolling in, with a 7-second period and a moderate 12 mph offshore wind from the north. Mewslade is an exposed bay, and the northern wind is blowing straight off the land, grooming those waves perfectly. Combined energy is a solid 303 – moderate, but with that offshore wind, the faces will be clean. This is the peak of the run. It’s fairly consistent here, but expect some company – crowds are sometimes a thing.

Then, another standout appears on Thursday the 24th of September. We’re looking at a 7ft west swell, 8-second period, and the morning goes glassy with absolute zero wind – a north-northwest breeze at only 3 mph. That’s a recipe for perfection. The energy jumps to 558, which is a very solid, powerful wave. This is an intermediate zone, but the wave height is getting up there. The afternoon shifts to a cross-shore, but for a few hours in the morning, it’ll be magical.

Now, a word of caution. The very end of the forecast, on Friday the 25th and Saturday the 26th of September, shows a very big southwest swell – 10ft and 12ft (Friday), with combined energies over 1200 and 1800. That is for experts only. The wind is light offshore off the east, so the waves will be clean, but that size at Mewslade will be intimidating and dangerous. It is simply too big for most.

So in short: grit your teeth through the first week. The real action is on Monday 21st for clean head-high, and Thursday 24th for a glassy, bigger morning session. The end of the month brings big, clean, expert-only surf.
