Table - best surf conditions forecast for Praia do Porto over the next 16 days.
Alright, Rusty here. Let's take a look at what Praia do Porto has in store for us over the next couple of weeks.
Right off the bat, Saturday the 11th is a bit of a washout. We’ve got some light rain and a cross-on breeze making a mess of things, with the water temp sitting at a very unusual 60°F, which is over three and a half degrees colder than normal for this time of year. That's a bit of a shock to the system. The surf is small and junky, not worth paddling out for.
Things start to turn around on Sunday the 12th. The morning is looking prime with a clean, moderate offshore wind from the SSW and a solid 4ft groundswell from the ESE. The wave energy is pumping at a strong 1154 (moderate to strong energy), and the period of 12 seconds means some nice, lined-up waves. Do keep an eye on that wind picking up in the afternoon though, as it swings cross-offshore.
Monday the 13th morning is another solid call. A 7ft swell from the S with a short, punchy period of 8 seconds and gentle offshore winds from the SW will have some fun, overhead waves. The energy is still good at 926. This is for the more experienced crew though, as over 5ft can be a handful for beginners. The afternoon cleans up but the swell drops right off.
Now, from Tuesday the 14th through to the 21st of July, it's mostly a write-off. We get a lot of onshore winds, cross-on breezes, and a lot of “poor surf conditions” stamped across the forecast. There are a few days with some size, like Tuesday morning with 7ft, but the wind is all wrong, making for choppy and messy waves. You're better off waiting this stretch out.
The real standout comes on Tuesday the 21st of July. We finally get a break in the weather with a light offshore breeze from the SW blowing clean over a 6ft swell from the NE. The wave energy is strong at 878, and the call is for “very good surf conditions.” This is the pick of the forecast, with good waves peeling down the beach/jetty setup. The period is short at 8 seconds, so expect a bit of a fat, powerful wall rather than a drawn-out line, but it’ll be clean and fun.
After that, Wednesday the 22nd and Thursday the 23rd offer some more clean, offshore conditions, but the swell drops down to around 4ft to 5ft. Still rideable, but not the highlight. The last few days from the 24th onwards look to fade out with onshore muck and small swell.
So, for the best bet: make a plan for the morning of Tuesday the 21st. It’s the only true standout in this whole run.
Rusty.
