Table - best surf conditions forecast for Barra do Sul over the next 16 days.
Alright folks, Rusty here. Let's take a proper look at what's on the cards for Barra do Sul.
Right now, we are in a bit of a flat spell. There's nothing worth paddling out for until Saturday, the 11th of July. That's a few days gap of really ordinary conditions where you'd be better off waxing your board and waiting.
The standout window opens this Saturday morning, the 11th. We’ve got a clean 3ft swell rolling in from the ESE with a period of 13 seconds. That's a nice long-period groundswell, packing a decent amount of punch for a wave that size. The combined energy is sitting at a solid moderate 354, and there’s zero wind – glassy as glass. Barra do Sul (Brazil) is pretty exposed to this direction, so expect some fun, clean lines. It’s a fairly consistent spot, but with these conditions the waves should be well-shaped for a beginner-friendly break. Conditions stay equally clean through the Saturday afternoon, which is a blessing.
We get a glimpse of the water temp here, and it's sitting pretty average for the time of year, so no surprises on that front.
Sunday the 12th keeps the quality going. Morning sees some clouds but a glassy 3ft from the ESE with that same long period, and the energy is still moderate at 235. It’s not quite the punch of Saturday, but the offshore wind from the NW is ideal. Perfect for those long, drawn-out rides. The afternoon holds up with a glassy 3ft from the SE. Just be mindful of a risk of thunderstorms later.
Looking further ahead, Wednesday the 15th morning looks promising again with a clean 3ft SE swell and a long 13-second period. The wind is light offshore from the west, so expect clean, peeling waves. This one is a solid, consistent option as we head into the middle of the month. The energy is on the moderate side at 274.
Then on Thursday the 16th morning, we get another glassy dawn patrol with a clean 3ft SE groundswell. The window of clean conditions stays open through the weekend of the 18th and into the 19th, but the swell does back off a touch.
If you’re looking for the best of the best, lock in Saturday the 11th and Sunday the 12th. Glassy, clean, and some nice long-period swell making for some proper fun waves.
Stay stoked,
Rusty
