The Lowdown
Alright folks, Rusty here, looking at what's on the menu for Praia do Porto over the next couple of weeks.
We've got a solid run of surf coming up, with a few standout sessions that are going to be well worth the paddle out. The first real action kicks off this Sunday, the 9th of August, and the energy is legit from the get-go. The water is sitting at 67°F, which is pretty much spot on for this time of year, so no surprises there.
Sunday morning starts with a 7ft south swell, but it's a bit short-period at 8 seconds, so it won't have the real grunt. The wind is howling from the SSW at 15 mph, which is offshore for this spot, so it'll be clean. The combined energy is solid at 1157 (moderate), making it a decent warm-up, but not the best of the window.
The real gem is going to be Tuesday, the 11th of August. We've got a 7ft south swell, but this time the period is a long 12 seconds, bringing proper groundswell energy. The morning is calling for glassy conditions, dead calm with a 3 mph offshore breeze from the SW. That's a recipe for perfection. The combined energy is pumping at 1521 (strong). This is the one to circle. For experienced surfers, this is going to be firing. The crowd factor is "sometimes" here, so expect a few others with the same idea.
Monday the 10th is also a great day, with a 8ft south swell and a 12-second period. The wind is a gentle offshore from the WSW at 9 mph, keeping it clean. The energy is even higher at 2707 (strong). This is a proper session, just a notch below the glassy Tuesday morning.
After Tuesday, the quality drops a bit. Wednesday and Thursday see the swell drop to 6ft and the wind turns more onshore, making it less ideal. There's a few windows of glassy conditions on Friday the 14th and Saturday the 15th, with smaller 4ft to 5ft swells. These are good for a beginner-plus surfer, clean and fun, but not the heavy hitters.
There's a rough patch from Sunday the 16th through Wednesday the 19th, where onshore winds and poor conditions make it a write-off. The swell is there, but the wind is trashing it. Then things start to look up again on Tuesday the 18th with a 7ft ENE swell and a clean cross-off breeze from the south. The energy jumps back to 1423 (strong), and it's a good option for experienced surfers, but the wind is a bit more tricky.
From the 20th onward, it fades. The last week shows small, weak swells with poor winds. The 23rd has a tiny 2ft south swell with a very long 12-second period, but the energy is a weak 187. It's not worth getting wet for.
Bottom line: Lock in Tuesday morning, the 11th of August, for the best chance at a glassy, powerful session. Monday the 10th is a very close second. If you're a beginner, Friday the 14th and Saturday the 15th are your best bet for clean, smaller waves.
Rusty.
