The Lowdown

Alright folks, Rusty here. Let’s break down what’s coming for this stretch of coast.

It’s a slow and messy start. For Wednesday and Thursday, the 29th and 30th of July, we’ve got a consistent 3ft to 6ft of swell, but it’s getting hammered by onshore winds. The water temp is sitting at about 58°, which is pretty much average for this time of year, nothing crazy. But the conditions are just ugly for surfing.

That pattern doesn’t really let up through the end of July and into the start of August. Friday through Sunday morning, the 31st to the 2nd, we see some size build, getting up to 8ft, and the combined energy is starting to show some muscle (over 1000), but the wind is still on it or cross-onshore. That 8ft on Sunday morning the 2nd is too big for beginners, and with that onshore breeze, it’s gonna be a walled-up mess. Honestly, it looks more like a kite-surfing setup than a paddling session.

The most promising window in this whole 16-day forecast is Monday the 3rd of August into Tuesday the 4th. We’ve got a 7ft swell from the NW with a 10-second period, and the combined energy is solid (1004). The wind is cross-onshore but light. It’ll be a little lumpy, but there’ll be some grunty waves to be had if you’re willing to work for it. For most folks, this is the best on offer, but it’s not a picture-perfect standout.

After that, the swell drops off dramatically. From the 5th of August onward, it’s small and weak. There’s a little pulse around the 7th and 8th with 5ft to 6ft and onshore winds, but it’s just not coming together. The waves get real small by the 12th and 13th, down to 2ft to 3ft, though the period stretches out to 16-18 seconds, a very long-period groundswell. That kind of swell can be glassy at point breaks and reefs, but at a beach break like Spanish Bay-South Moss, it’ll likely break too straight and be a bit of a letdown. And with the winds turning cross or cross-onshore, there’s just nothing to rush out for.

Bottom line: There’s no perfect, crystal-clear winner here. Monday the 3rd is your best bet for some size and power, but don’t expect perfection. The rest of the run is a lot of small, wind-affected, or just plain messy surf. It’s one of those stretches where we need the forecast to shift in our favor.

Rusty.
