Alright, let's have a look at what we've got for Mewslade Bay over the next couple of weeks.
Right off the bat, I’ll be straight with you – this is a tough one. We’re looking at a real quiet stretch. The first bit of action that’s even worth mentioning is Thursday morning, July 2nd. We’ve got some waist-to-chest high swell coming in from the west at 6ft, with a short period of 8 seconds. The water is sitting at a very unusual 66°, which is about 8° warmer than normal for this time of year – that’s pretty wild, you’ll be surfing in a spring suit no problem. The wind is a moderate cross-offshore from the NW at 16 mph, keeping the surface clean. The combined energy is moderate at 337, but honestly, the conditions are marginal and the score just isn’t there. It’s a bit of a tease.
That afternoon, the swell drops to 4ft, still from the WSW, but the wind stays cross-off. It’s clean, but again, nothing to write home about.
From Friday, July 3rd, all the way through to Thursday, July 16th, it’s a flat spell. We’re talking tiny, weak waves – nothing above 2ft for days on end, and most of it is even smaller. The combined energy drops into the double digits and even single digits (69, 46, 15... even a 4 at one point), which is basically no energy at all. The winds are a mix of cross-on, cross-off, and sometimes clean, but there’s just no swell to work with. It’s a proper lull.
We finally get a slight flicker of hope on Wednesday, July 15th, with a tiny 1ft from the WSW and a short period of 8 seconds, but again, it’s not enough for a decent paddle.
The best of a bad bunch, if you’re desperate for a paddle, is that Thursday morning, July 2nd. The swell is the biggest we see in the whole window, the wind is clean, and that warm water is a bonus. But don’t expect any kind of quality. For the rest, it’s a solid two-week dry spell. Mewslade Bay is fairly consistent normally, so this is a bit of a bummer, but it happens. Forecasts can change.
Stay tuned, and keep an eye on the charts.
