Mewslade Bay Surf Forecast and Surf Report

Right then, let’s have a look at what’s on the cards for Mewslade Bay. I’m not gonna sugar-coat it; this is a rough run. The forecast is showing a whole lot of "poor surf conditions" right across the board with zero scores, so there’s no standout session to get excited about. We’re looking at a 16-day window with no real recommendations. The first few days are a write-off and honestly, it doesn’t get much better. There’s a bit of a gap here with nothing worth paddling out for, and given the pattern, this blank run is pretty normal for the area when the wind and swell just don’t line up.

Let’s talk about the water. When we do look at the first bit of swell, the water temperature is sitting at 66°F with an anomaly of 5°F, which is much warmer than normal for this time of year. That’s a notable bump, but it doesn’t mean much if the waves are junk.

We start off Saturday, September 5th. Morning has a 3ft swell from the west with a weak 7-second period and a combined energy of just 153 (weak energy). Wind is WNW 15 km/h (9 mph), so it’s a cross-shore breeze creating a slight cross-chop. Afternoon drops to 3ft, still choppy, and it’s all poor conditions. Sunday the 6th is even smaller, with 2ft and 3ft, period dropping to 6 seconds, and onshore winds making it messy. Not worth a look.

Monday the 7th brings a jump in size to 6ft in the morning and 7ft in the afternoon, with a longer 13-second period, so there’s some groundswell energy. The combined energy hits 1590 (moderate wave energy) in the morning. But the wind is cross-onshore at 25-30 km/h (16-19 mph), making it lumpy and choppy. That swell size is over 5ft, so it’s getting too big for beginners, but the wind is trashing it. This would be more interesting for kite surfing than paddle surfing given the poor quality and strong wind.

Tuesday the 8th is still 5ft with a 10-second period, but the wind stays fresh cross-shore and lumpy. Energy drops through the day. Not good.

Wednesday the 9th sees a drop to 4ft, and the wind finally goes cross-offshore from the NW at 25 km/h (16 mph), giving us clean conditions. The period is short at 7 seconds though, and the energy is only 130 (weak). It’s clean, but there’s just not enough juice.

From Thursday the 10th right through to the end of the period on September 20th, it’s a mix of onshore winds, rain, and tiny surf. Thursday the 10th has 6ft but with a 6-second period and fresh onshore wind – lumpy junk. Friday the 11th is cleaner with cross-offshore winds, but the swell is only 6ft with a 6-second period, so it’s bumpy and short period, not worth the drive. The rest of the days are tiny, from 2ft down to 0.3ft, with periods all over the place. Even though some mornings are clean with offshore winds, the swell is just pathetic. On the 19th and 20th, there’s a brief whisper of a long-period swell from the SW at 14-16 seconds, but it’s only 0.3ft, so it’s a tease.

Honestly, there’s nothing here. The best you could hope for is a clean but tiny wave on September 9th or 11th, but it’s not worth getting wet for. Keep the board in the truck and wait for the next proper swell.
