The Lowdown

Alright, this is Rusty. Let’s talk about Barvas.

There’s a bit of a wait for the good stuff. The main event kicks off Wednesday morning, August 19. You’ve got a 6ft swell rolling in from the west with a 10-second period – that’s proper groundswell, got some energy behind it. The combined swell energy is sitting at 758, which is moderate but solid. The wind is light offshore from the ESE at 6 mph – that’s glassy, clean conditions. This is the standout session. Water temp is 58°, about average for this time of year. Barvas is a reef break, and with that offshore wind, it’ll hold shape nicely. Crowds are rare, so you’ll likely have it to yourself.

Wednesday afternoon, the wind swings to a fresh NE at 22 mph – cross-off, but energy drops and it’s only marginal.

Thursday, August 20, is a no-go. Northerly winds at 19-22 mph, cross to cross-on, lumpy and chopped up. The swell is 7ft but with a short 8-second period – ugly.

Friday, August 21, is more cross-onshore garbage. Nothing worth paddling out for.

Saturday, August 22, has a brief clean morning window with offshore wind from the WNW at 12 mph, but the swell is only 4ft and the energy is dropping. Afternoon goes cross-on again.

Sunday, August 23, is all cross-onshore and choppy – skip it.

Monday, August 24 – this is another highlight. Morning shows a 8ft west swell with a long 11-second period. Combined energy jumps to 1310 – that’s strong, powerful. Wind is light S at 16 mph, cross-off, so the face is clean. This is expert territory – over 8ft is serious. If you’ve got the experience, this morning is the second best of the whole forecast.

Tuesday, August 25, is small but clean – light cross-off wind, waves around 4ft. Easy paddling, fun for beginners.

From Wednesday, August 26, the swell drops right off – tiny 2ft waves, energy in the 60s and 90s. By Thursday, August 27, the wind pipes up from the SSW at 22 mph – fresh cross-shore, lumpy. Better for kite-surfing at that point.

Friday, August 28, through the end of the month is mostly small and messy. A few clean moments on Saturday, August 29, morning with barely 2ft waves. Not worth the trip.

Wednesday, September 2 – long range but worth noting. Morning shows a 8ft WNW swell with 8-second period, combined energy 760. Wind is light NNW at 9 mph, cross-on, so a bit choppy but still surfable for the crew who don’t mind a little texture.

Then Thursday, September 3 – the final gem. Morning has a 4ft west swell with 9-second period, and the wind goes glassy offshore from the ESE at just 3 mph. Afternoon is even better: glassy conditions with a light WNW breeze at 3 mph. That’s clean, lined-up reef surfing. The energy is low-moderate at 318, but on a reef like Barvas, that’s enough.

So, the best is Wednesday, August 19, morning. Second best is Monday, August 24, morning for the big-wave crew, and then Thursday, September 3, morning for clean small waves. Keep an eye on that last one – it’s promising.

Rusty.
