The Lowdown
Hey folks, Rusty here. Let’s talk about what’s cooking at Atalaia (Molhes) for the next couple of weeks.
The first few days are a bit of a write-off, to be honest. We’ve got a rough start with poor surf conditions and chop. Saturday the 5th and Sunday the 6th are a no-go, with small, weak swell and cross-shore winds messing things up. The combined energy is low, around 135 to 155 (moderate), but it’s just not clean.
Monday morning the 7th is a slight glimmer – a tiny 1ft swell from the SE with a period of 11 seconds, and the wind is light cross-off, making it clean. But it’s very small. The energy is weak (84).
The first real standout window opens up on Tuesday morning, the 8th. We’ve got a solid 6ft swell from the ENE, period 7 seconds, and the wind is cross-off and clean. The combined energy jumps to 546 (moderate) – you’ll feel that push. It’s a bit short-period, but the conditions are good for a Tuesday morning session. Wednesday morning the 9th is also worth a look, with 5ft from the ENE, clean cross-off wind, and energy at 305 (moderate).
Now, for the absolute best of the whole run, you want to circle Sunday the 13th, morning. The swell is pumping 8ft from the SSE with a period of 10 seconds, and the wind is gentle offshore from the WSW – clean, clean, clean. The combined energy is a massive 1659 (strong) – this is a serious groundswell. This is for experienced surfers only; it’s too big for beginners. The direction is straight out of the optimum SSE direction for this spot.
Tuesday the 15th, morning, also looks serious. Another 6ft from the ESE, but with a very long period of 14 seconds and glassy conditions. The energy is 1490 (strong). That long period will make the waves fat and powerful, best for a reef or point setup, but at Atalaia (Molhes) it’ll still reel off. Again, this is for the experienced crew.
There’s a bit of a lull in the middle of the second week, with more marginal conditions, but then the very end of the forecast has a nice run of clean, glassy mornings around the 17th, 18th, and 19th. Swells around 4ft to 4ft, with period between 7 and 13 seconds, and the combined energy is moderate (300-644). The 19th, Saturday morning, is glassy with a 4ft swell from the ESE – that’ll be a fun, easy session for all levels.
Bottom line: the first week is rough, but the 8th and 9th are clean. The standout is Sunday the 13th morning for the big, clean, powerful swell. The 15th morning is also a high-quality, glassy, long-period option for experienced surfers. The last few days of the window clean up nicely too.
Rusty, signing off.
