The Lowdown
Alright, Rusty here. Let’s look at this stretch of water.
Right off the bat, the first week and a half is a real bummer. We’re looking at a dry spell of several days where the surf is just not worth a mention. It’s small, the conditions are off, and it’s a whole lot of nothing.
The first chance to get wet is on Monday, July 20th, but it’s a weak one. Spanish Bay-South Moss is showing a 0.7m (2ft) swell from the southwest, with a super long 16-second period. That’s a deepwater groundswell, but at that size, it’s got no grunt. The water’s a bit colder than usual, about 56°, with a moderate combined energy of 517. The morning has a light offshore breeze, but the afternoon goes cross-onshore. It’s a pass.
The whole next week is more of the same. Small, inconsistent swells, and the wind is never quite right. The energy numbers are all over the place, like a big 1184 on the 24th, but that’s a 0.7m (2ft) swell with a 24-second period. That’s a crazy long period, which can make things weird and slow at a beach break. It’s a tease.
The only thing that looks even a little bit interesting is Monday, July 29th. The swell jumps to 1.9m (6ft) from the northwest, but it’s a short 9-second period. That’s a windswell, so expect it to be lumpy. The energy is strong (1092), and the morning has a moderate offshore wind. At 1.9m (6ft), it’s getting a bit too big for beginners. It’s the best of a bad lot, but it’s not a day to get stoked about. The rest of the period is just more of the same short-period, wind-affected stuff.
For the whole 16 days, there’s nothing that’s a real standout. If you’ve got to get out, the morning of the 29th has the most size, but don’t expect any magic. Honestly, this whole stretch looks more interesting for kite surfing than paddle surfing.
Rusty, out.
