Table - best surf conditions forecast for Mewslade Bay over the next 16 days.
Rusty here, and I gotta tell ya, it’s a brutal outlook for the next couple of weeks. We’re looking at a whole lot of nothing for a long, long time.
For the first 15 days, we are basically flat. Tiny, knee-high slop and poor surf conditions are all that’s on offer. There’s a massive gap of quiet water. It’s a tough stretch, but honestly, it’s not that weird for this spot; the ocean just shuts down sometimes.
The only day that even registers is Thursday, July 23rd. By the morning, a new swell pushes in, reading 5 ft from the SW. The water temp is a balmy 67.5° , which is *much warmer than normal* for this time of year. But don’t get excited. The wind will be howling at 19 mph from the SW, right onshore and lumpy. The combined energy is moderate at 189, but the period is a crappy 6 seconds. It’s going to be a messy, blown-out wall of chop. By the afternoon, the wind picks up to a nasty 25 mph from the WSW, making a 7 ft swell a total washing machine (energy at 437). That size is for experts only, and with that wind, it’s just ugly.
That’s all there is. Mewslade Bay is a write-off until that last blustery day. A long wait for a messy, powerful ocean. Keep the board waxed for another time.
