The Lowdown
Alright, folks. Rusty here. Let’s break down the surf for Barvas (Lewis) over the next couple of weeks. It’s a rough start, so don’t get your hopes up too early.
We’re looking at a real dry spell from the 10th through the 15th of September. Thursday the 10th to Tuesday the 15th is mostly a washout. The swell is there – you’ll see some moderate to strong energy (245 to 3232) – but the wind is a mess. Cross-off, cross-on, onshore slop, you name it. It’s not happening for paddle surfing.
Then, on Wednesday the 16th, things finally turn. The morning is glassy and clean with a light NE breeze. The swell is a solid 7ft from the west, period of 10 seconds, and the combined energy is moderate (1213). This is the standout for the experienced crew – it’s too big for beginners (over 8ft), but for those who can handle it, the clean conditions and cross-off wind make it the best of the run. The water temperature is about average for the time of year. The afternoon drops to 5ft, still clean and glassy – a real gem.
Thursday the 17th brings another big morning. We’re talking 10ft from the west with a long period of 11 seconds, and the combined energy is strong (2127). The wind is light and cross-off, so it’s clean. That’s expert-only territory. The afternoon gets a bit lumpy with cross-shore wind.
After that, it’s a slide back into mediocrity. Friday the 18th and Saturday the 19th are marginal, with moderate cross-shore winds and lumpy chop. The energy drops off (741 to 1020), and the quality is poor.
The second week gets wild. Sunday the 20th and Monday the 21st show big swell again (10ft, 13 seconds), but the wind is fresh cross-shore or strong cross-on, and the combined energy is very strong (3479 and 3146). It’s a kite surfer’s dream, not a paddle surfer’s.
The rest of the week into the 25th is a write-off. Strong onshore winds, massive swell (15ft to 18ft), and huge combined energy (over 7000 to 8800). It’s messy, dangerous, and blown out. Not for the paddle surfer.
So, to bottom line it: Wednesday the 16th of September is the best on offer – clean, glassy, and a solid west swell. Thursday morning the 17th is also a big-wave standout. The rest is either too small, too windy, or too big and messy. Keep an eye on the forecasts, but that’s the call.
Rusty.
