The Lowdown
Alright folks, Rusty here. Let’s get straight into it.
First up, the water’s a bit colder than usual for this time of year, sitting at 56°F with a 2°F anomaly. It’s noticeably cool, so a good 4/3 might be the call.
We’ve got a long run of days ahead, but honestly, the surf is looking pretty slim for the first week. The real action doesn’t fire up until we get closer to the end of the month and into early August. The first few days are a bit of a write-off, with small, weak swell and poor conditions. There’s a big gap of marginal to poor surf from Monday the 20th right through most of the following week.
The first real flicker of life comes late on the 28th of July, but it’s messy. The standout, the one to get a little excited about, is the morning of the 28th of July at Spanish Bay-South Moss. The combined swell energy is pumping at 1291 (moderate to strong), with a clean 3ft of SSW groundswell rolling in at a nice long 18-second period. The wind is light and offshore from the WNW, which should keep the surface glassy. This is a solid, clean option, but the swell is small enough for a longboard or a fish. The long period means it’ll be a bit more lined up, but at a beach break it can get a bit sectiony. Still, for the best wave quality in the lull, this is it.
Later on the 28th, the swell jumps to 8ft, but it’s a short-period NW windswell (9 seconds) with cross-onshore winds. That’s going to be a bit of a choppy mess, better left for the kites.
The next true standout window opens up on the 3rd of August morning. Monday morning the 3rd, we’re looking at a clean 7ft of NW swell, period up to 10 seconds, and light offshore wind from the WNW. The combined energy is 792 (moderate). This is a proper size, still manageable for a confident intermediate, but at 7ft it’s getting into the “watch out” zone for beginners. The 4th of August morning looks similar, with 7ft of NW swell and light offshore wind. Those two mornings are the pick of the whole outlook.
Crowds are possible at Spanish Bay-South Moss, so get in early or be ready to share.
So, if you’re keen, bank the 28th of July morning for a clean, classy little wave, and then pencil in the 3rd and 4th of August mornings for the bigger, punchier stuff. The rest of the fortnight is either too small, too windy, or too messy to get excited about.
Rusty.
