The Lowdown

Alright, Rusty here. Let’s talk about what’s on the table for the next 16 days. Straight up, it’s a pretty bleak run for the most part. We’re looking at a long stretch of onshore winds and marginal conditions, so don't get your hopes up too high. There are a few windows, but they’re not for the faint-hearted.

The only real standout to even talk about is Spanish Bay-South Moss. This is an advanced wave, so it’s not for beginners. The first chance to get wet is on Tuesday, July 21st. The morning will be a bit messy with a 3 ft SSW swell at 14 seconds, but the wind is cross-shore, so it could be rideable. The afternoon is better: the swell picks up to 4 ft from the same SSW direction, and the wind goes cross-offshore, cleaning it right up. The wave energy is moderate (751), and the water temp is sitting at 57°, which is pretty much normal for this time of year. The swell period is a long 14 seconds, so it’s a groundswell, which will make for nice, lined-up waves, but the gaps between sets will be longer.

Wednesday, July 22nd is a write-off. The wind swings cross-on both morning and afternoon, and the wave quality is poor. The swell drops off, and conditions are just choppy and ugly.

From Thursday, July 23rd all the way through to Monday, August 3rd, it’s a long, painful stretch of straight onshore winds. The swell sticks around, mostly from the SSW and SW, but with the wind howling directly on it, it’s just a blown-out mess. The wave energy is moderate to strong (values between 405 and 1332), but none of that matters when the wind is ruining the face. For advanced surfers, it might be interesting to see the bigger days, but for paddle surfing, it’s a no-go. This setup looks more interesting for kite surfing than paddle surfing for most of that time.

Around Tuesday, July 28th and Wednesday, July 29th, the swell direction shifts to the NW, and the height jumps up to 6 ft. But the period drops to 9 seconds and then 8 seconds – that’s short-period, wind-driven junk. And the wind is still onshore or cross-on. It’s a big, messy close-out. This is expert-only territory if you’re even thinking about it, and honestly, it’s not worth the paddle.

The final week, from August 1st to 5th, the swell drops back to 4 ft to 6 ft, but the period is a pathetic 7 to 8 seconds. The wind is either onshore or cross-on, and the comments are all “poor surf conditions.” There’s no redeeming this stretch. The wave energy is weak to moderate (203 to 482), nothing to write home about.

So, the one and only true standout is Tuesday afternoon, July 21st at Spanish Bay-South Moss. Clean, cross-offshore wind with a solid 4 ft groundswell. That’s your best bet. The rest of the 16 days? A long, dry spell. Don’t hold your breath.

Rusty.
