Alright folks, Rusty here. Let’s have a look at what’s coming up for the next couple of weeks. I’ll be honest, we’ve got a bit of a rough patch to get through before we see any real quality.
Right now, the outlook is pretty grim. The first real chance for a wave won’t be until the 8th of July, and even then, it’s nothing to write home about. The wind is straight onshore from the WSW, pushing in a messy 5ft cross-chopped swell with moderate energy (693). It’s a struggle session, not a fun one.
We’ll see a glimmer of hope on the morning of the 9th of July. The wind swings cross-offshore from the S, cleaning up a 5ft SW groundswell (9 seconds). The energy is moderate (574), and the surface will be clean. It’s still marginal, but it’s the first time the wind isn’t wrecking it. After that, the surf drops right off. From the 10th right through to the 18th of July, we’re looking at a long stretch of tiny, weak waves or poor conditions. There’s a few days with clean offshore winds, particularly on the 17th and 18th, but the swell is small and weak, with energy values barely cracking 100. It’s a flat spell, plain and simple.
Now, here’s the standout. If you’ve got patience, mark Sunday the 19th of July on your calendar. Early morning, the stars align. We’ve got a solid 8ft swell from the WSW, with a moderate 9-second period, packing strong energy (1048). The wind will be a light offshore from the SE, making for clean, well-shaped waves. This is the only day in the whole window that’s worth a serious look, but it’s a big one. That said, 8ft is getting into expert territory, so this isn’t the day for beginners. The afternoon of the 20th of July also looks promising with a glassy clean 6ft NW swell and moderate energy (535), a nice follow-up for the more experienced crew.
The water temp at Ersary beach (Barra) is sitting at 56°, which is pretty much average for the time of year, so no surprises there.
So, to sum it up: the next week and a half is mostly a write-off. The real action, and the only true standout, is the morning of the 19th of July. Be ready for it.
Rusty.
