Sao Lourenco Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Alright, we’ve got a bit of a slow start, but there’s some real magic brewing later on. The first few days are a bit of a mixed bag, but the real standout is gonna be the long-range stuff. The water temp is sittin’ right on 68°, which is about average for this time of year, nothing to write home about.

First up, Tuesday the 14th is a bit of a tease. Sao Lourenco (river) is showing some glassy conditions in the morning with a 5ft SSE swell, period of 10 seconds, and combined energy of 405 (moderate). It’s a river mouth, so the swell direction is a bit off the optimum, but with calm winds, it’s worth a look. By afternoon, the wind switches onshore and it gets a bit messy.

Wednesday the 15th is a better bet. The morning is glassy again, with a 5ft SE swell, 10-second period, and energy of 495 (moderate). This is the best of the early window. The wind is offshore from the NNE, so it’ll be clean. The afternoon sees the swell drop off a bit.

Thursday the 16th through to the 21st is a pretty lean run. The swell drops down to under 3ft, and the period shortens up to 8 seconds. The wind is mostly cross-off or cross-shore, so it’s not a total washout, but it’s small and weak. Saturday the 18th is a write-off with 12 mph winds. The energy drops below 100, so it’s just small, weak, and ordinary. You’re lookin’ at a solid week of small, choppy conditions.

Then things get interesting. On Tuesday the 22nd, a new pulse of swell arrives. The morning shows a 5ft S swell, but the period is short at 6 seconds, so it’ll be a bit choppy and messy. The energy jumps to 307 (moderate). The wind is offshore from the NNW, so it’ll be clean on the face, but that short period means it’s not gonna be the best shape.

Hold on to your board, because Thursday the 23rd is the real standout. The morning is glassy, with a 4ft S swell, 13-second period – that’s a proper groundswell. The energy is 613 (strong). This is the best on offer. The wind is glassy, so it’s gonna be clean as a whistle. The long period means it’ll break straight at the river mouth, but it’s a river, so it should be fine. This is the one to mark on your calendar.

Friday the 24th is also a cracker. Morning is glassy, with a 4ft S swell, 12-second period, and energy of 649 (strong). It’s smaller than Thursday, but still very clean. The afternoon sees the wind turn onshore.

After that, the swell drops back down through the weekend and into the next week. The 25th and 26th are small, with ESE swell and shorter periods, and the wind is cross-off, so it’s surfable but ordinary. The 27th and 28th are small and weak again, with the 28th having a bit of a pulse in the afternoon from the south with a long period, but the wind is cross-on, so it’s a maybe.

The 29th has a solid morning with a 5ft S swell, 10-second period, and energy of 425 (moderate), with clean cross-off winds. The afternoon goes glassy with a smaller swell.

So, to wrap it up: the first week is a write-off after Wednesday. The real magic is Thursday the 23rd and Friday the 24th – get on it. The long-range stuff on the 22nd and 29th are worth a look, but the 23rd is the clear winner.

Rusty.
