The Lowdown
Alright, let’s talk about what’s cookin’ for the next couple of weeks. Gotta be honest, the first few days are a total bust. There’s a big gap with no surf worth paddling for, thanks to messy winds and a real ugly sea state. It’s a slow start.
The first real chance to get wet and actually enjoy it is on Tuesday, the 11th of August. That’s the one to focus on. Barvas (Lewis) is the spot. Head out in the morning. The wind is a light cross-offshore breeze from the SSE at 15 km/h, and that’s a beautiful thing – it’ll keep the surface buttery smooth. We’ve got a clean swell pushing in from the North at about 4ft, with a period of 10 seconds, so there’s some decent power there. The combined swell energy is moderate (506). The water’s around 57°, which is pretty standard for the time of year. It’s a reef break, so that longer period swell will wrap in nicely. It’s a beginner-friendly wave, and with crowds being rare, you’ll likely have it all to yourself. This is your best call. The afternoon holds up pretty well too, just a little less oomph.
The next morning (Wednesday, 12th of August) has a smaller, weaker swell coming in at 3ft from the WSW, but with a super long period of 12 seconds. That’s proper groundswell. The wind’s light and offshore again, so it’ll be clean, but the energy is weak (273). It’s a bit of a gamble on size.
Looking further out, Saturday the 15th of August shows a pulse of 7ft from the WNW. The wind is a moderate cross-offshore, but the period is a short 8 seconds, so it’ll be a bit choppy and lack punch. The energy is moderate (510). It’s a long way out, so don’t book your flights yet.
The rest of the second week is mostly onshore wind and weak, messy slop. The window closes fast. The 11th is your day. That’s the one.
