The Lowdown
Grab your board, folks—Rusty here. We’re looking at a stretch of mostly ordinary days ahead at Praia da Foz Cabo Espichel Sesimbra, with a couple of early-morning windows that should get your attention. The water’s sitting at 69°, about average for the time of year, so no surprises there.
The first solid window kicks off Sunday morning, the 16th. That’s the standout of the whole run—swell’s a clean 5ft from the NW, period 9 seconds, and it’s glassy, with barely a breath of wind. Energy’s moderate at 369, and those waves will have some push. It’s a reef setup, fairly consistent, and it’ll handle that NW swell nicely—this is the one to make the most of. Expect a bit of crowd, though, as word tends to get out.
Monday morning, the 17th, brings another clean one: 4ft from the NW, same 9-second period, with a light offshore from the SE. Energy’s at 292, moderate, and it’ll be clean and lined up. Not as big as Sunday, but still plenty fun. If you can only get out once, aim for Sunday AM; Monday’s a solid backup.
After that, tide turns. The rest of the 17th, through the 19th, gets messy with cross-onshore winds and choppy conditions—surf drops to 2ft by the 19th, and energy fades to around 97-125. That’s weak, and not worth paddling out for. There’s a brief blip on the 20th morning when a longer-period 11-second swell shows up at 2ft, but the wind’s on it, so it’ll be lumpy.
Then the second week rolls in—the 21st through the 27th—and it’s mostly a write-off. Swell builds to 6-6ft from the NW, but winds are strong, cross-onshore, and relentless. That’s mess, not surf. Energy gets up there—508 on Friday the 21st, 691 on Saturday the 22nd—but with 18-22 mph winds, it’s just blown-out chaos. There’s a slight hint of relief on the 24th, but it’s onshore, short-period, and grovelly. By the 25th and 26th, winds pick up again into the strong range, so don’t get your hopes up.
Honestly, the best bet is the Sunday/Monday window early on—clean, glassy, and lined-up. After that, it’s a whole lot of chop for the forseeable. If you’re not out Sunday morning, you might as well wait out the week.
Rusty out.
