Right then, let’s have a look at what’s on the cards for Mewslade Bay.
To be straight with you, it’s a tough stretch ahead. For the next two weeks, almost every day is a write-off. The swell is tiny, the wind is mostly junk, and the surf is just poor. We’re looking at a solid 15-day gap before anything worth getting wet for shows up. That’s a long, quiet spell.
The water is sitting at 66° on the Friday morning of the 3rd of July, which is much warmer than normal for this time of year – a solid 8° above average, so you won’t need a thick suit, just a whole lot of patience.
Through the first week and into the second, we’ve got nothing but small, weak waves. The combined energy is a joke – mostly two-digit numbers in the teens and twenties, with the odd weak three-digit reading, but it’s all coming with cross-onshore or cross-shore wind, keeping everything choppy and messy. The odd clean window pops up, like on Wednesday morning the 8th of July with a light offshore, but the swell is only 1ft from the west with a short 8-second period – barely a ripple.
There’s a brief flicker on Saturday the 11th of July afternoon when it goes glassy, but again, it's a dead 0.7ft swell. Not a wave in sight.
The only real glimmer comes on Saturday the 18th of July. The morning shows a jump: a 6ft swell from the southwest with an 8-second period, and the combined energy is a solid 362 – moderate wave energy. The wind is light and cross-offshore from the northwest, so it’ll be clean. For Mewslade Bay, a southwest swell is in the optimum direction, so this is the one. However, by the afternoon the wind swings onshore and ramps up to 16 mph, turning it choppy, and the swell jumps to 7ft, which is getting into expert-only territory, especially with a short period. The morning session on the 18th of July is your only real shout. The crowd factor at Mewslade can be ‘sometimes’ busy, but on a day like this after such a long flat spell, you might get lucky.
Don’t hold your breath for anything before that. This is a proper dead run. Forecasts can change, but right now, it’s a waiting game.
