The Lowdown
Alright, let’s break down Praia do Porto for the next couple of weeks. The water’s sitting at 67°, which is about average for the time of year, so nothing out of the ordinary.
The first proper swell hits this Saturday afternoon, the 22nd of August. It’s a 7ft S swell with a cross-off wind, but it’s a bit marginal. The combined energy is moderate (843). The real fun starts Sunday morning, the 23rd. We’ve got a 7ft S swell with an 11-second period and light offshore winds from the SW. That’s clean and decent. The afternoon kicks up a notch for the more experienced, with a 8ft S swell and a 12-second period, though the wind shifts cross-off.
The crown jewel is Monday morning, the 24th of August. Glassy conditions, a 10ft S swell with a very long 14-second period, and the energy is pumping at 3253. That’s strong. The swell direction is right on the money. This is a serious swell for experts only – at over 8ft, it’s too big for beginners. The long period will make it a bit straight at the beach break, so look for a point or a reef if you can.
Things go downhill from Tuesday the 25th through the rest of the week, with onshore winds and poor conditions. The 28th of August Friday afternoon offers a brief reprieve with a 6ft ENE swell and glassy conditions, but it’s a short period (8 seconds) and low energy (558).
The first week of September has a few highlights. The 31st of August Monday morning is glassy with a 4ft ENE swell, though the energy is low (430). The 3rd of September Thursday morning is promising with a 6ft S swell, clean cross-off winds, and a 9-second period. The energy is moderate (675). But the 4th of September Friday looks like a write-off, with onshore winds and a drop in quality.
The second week is a bust. The 5th and 6th of September are poor, with onshore winds and short-period junk. The energy is weak (211 to 269). The 1st of September Tuesday afternoon is a possible pick for a clean session, but it’s not a barnburner.
For the best sessions, go for the Sunday the 23rd morning and the Monday the 24th morning. The Monday is the big one for the experienced surfers, but the Sunday is a solid, clean option.
