The Lowdown
Alright, folks, Rusty here. Let’s break down what’s cookin’ for Mewslade Bay over the next couple of weeks.
Right off the top, this is a tough stretch. We’re lookin’ at a 16-day window, but honestly, there’s not a single standout session in the whole run. The surf is consistently small, the energy is weak, and we’ve got a lot of poor surf conditions flagged up. The first few days are a non-starter, with tiny waves and messy wind. From Sunday the 2nd right through to the end of the first week, the swell barely cracks 3 ft, and the combined energy is pitiful, sittin’ between 20 and 234—nothin’ to get excited about. The water temperature is about average for the time of year, so no surprises there.
Monday the 4th sees a slight bump in swell, hittin’ around 4 ft from the SW, but it’s onshore wind and short period (7-8 seconds), so it’s gonna be choppy and weak. The energy climbs a bit to 129-165, but that’s still moderate at best. By Wednesday the 6th, wind picks up to 18 mph from the W, makin’ it lumpy and cross-onshore, and the swell is only 5 ft—still too small for any real power. Honestly, this stretch is more suited for a kite than a paddle, with the wind and chop.
The second week doesn’t get much better. From the 8th onwards, we’re lookin’ at tiny waves, mostly under 2 ft, with periods all over the place. There’s a brief moment on Saturday the 10th with clean offshore winds (N, 3 mph) and a 2 ft swell, but it’s just too small to ride. The energy is barely registerin’, with values like 11-64. The week of the 12th to the 17th is a write-off – swell drops to 1.0 ft, and the wind is either cross-off or onshore, but the waves are just too small to mention.
The only glimmer comes on Sunday the 8th, when we get a glassy mornin’ with 0.7 ft swell from the W, but that’s just a flat calm. No, there’s no real "best on offer" here. If you’re desperate, the 2 ft clean conditions on the 10th mornin’ might be a paddle, but that’s it. The break is a beach setup, exposed to SW swell, but it’s inconsistent and rarely breaks properly.
So, in short – this is a blank run. It’s a bummer, but it’s normal for this area when the Atlantic ain’t givin’ us love. Forecasts can change, but for now, keep the board in the bag.
Rusty.
