Table - best surf conditions forecast for Praia do Porto over the next 16 days.
Alright, let’s get into it. The outlook starts on Friday, July 10th, with a bit of a slow build. We’ve got a window of surfable waves, but it’s not all plain sailing.
The first proper call is for Friday morning, July 10th, at Praia do Porto. It’s glassy out there, with a light SW breeze at 3 mph, and the swell is a clean 3 ft from the ESE. The period is a solid 12 seconds, so there’s some groundswell energy pushing through. The combined energy is moderate (288). It’s a beginner-friendly spot, so if you’re looking for a gentle paddle, this is it. The water temperature is about average for this time of year, nothing wild.
Friday afternoon stays clean, with a cross-off breeze and the swell bumping up to 4 ft. The energy jumps to moderate (401). Still a good session, but the wind is a little more sideways.
Now, Saturday, July 11th is a write-off. The wind shifts to a cross-on from the NNE, and the conditions get choppy. The swell is there, but it’s messy. The combined energy is moderate (719) on Saturday morning, but it’s not worth it. We’ve got a blank day.
Sunday, July 12th is the first real standout. Sunday morning is where it’s at. The wind is offshore from the WSW at 6 mph, and the swell is 5 ft from the ESE with a 12-second period. The combined energy is strong (1017). This is a clean, well-shaped wave. It’s a bit over the 3 ft mark, so beginners might find it a handful, but for the rest of us, it’s a beauty. The afternoon gets messy with a strong cross-off wind and rain, so get it early.
Monday, July 13th, has a solid morning session. The swell is 5 ft from the S, but the period drops to 8 seconds, so it’s a bit weaker. The wind is offshore from the SW, though, so it’s clean. The energy is moderate (490). Not a standout, but a solid session.
From Tuesday, July 14th, through to Sunday, July 19th, it’s a long, frustrating gap. The wind is mostly cross-on or onshore, and the swell is either small or short-period junk. The energy values are low to moderate, but the conditions are just poor. Kites might have a better time with the onshore winds, but for paddle surfing, it’s a tough stretch. There’s nearly a week of no good surf.
Friday, July 17th morning, there’s a glimmer. The swell is 6 ft from the NE, with an offshore SW wind at 6 mph. The energy is strong (802). But the period is only 8 seconds, so it’s a bit lumpy. It’s a one-off clean window in the middle of a messy period.
The next real hurrah comes on Wednesday, July 22nd morning. The swell is 6 ft from the NE, with a clean offshore wind from the SSW. The energy is strong (817). The period is still short at 8 seconds, but the conditions are clean. It’s a good session, but not a classic.
Then, the final standout is Thursday, July 23rd. The whole day looks fantastic. The swell is 5 ft to 6 ft from the S and SSE, with a very long period of 11 seconds. The wind is glassy from the NNE, at just 3 mph. The combined energy is strong (827 in the morning, 1030 in the afternoon). This is the best on offer in the whole outlook. The water is flat, the waves are clean, and there’s real power. The swell direction is from the S, which matches the optimum direction for this spot. The only caveat is that with a long period, a beach break like this might close out a bit, but the quality is undeniable.
After that, Friday, July 24th, and Saturday, July 25th, see a big jump in size. The swell hits 8 ft to 12 ft, but the wind is onshore or cross-on, and the conditions are poor. This is expert-only territory, and even then, the wind ruins it. The energy is very strong (2437 to 5709), but it’s a mess.
So, to wrap it up: grab Sunday morning, July 12th, for the best early session, and circle Thursday, July 23rd, as the absolute standout. Everything else is a gamble or a write-off.
