The Lowdown
Alright, Rusty here, let’s break down what’s happening at Atalaia (Molhes) over the next couple weeks.
First off, the early days are a write-off. Saturday the 12th is choppy with cross-onshore wind and weak swell. Your first real chance is Sunday morning the 13th: a 5ft S swell, period around 7 seconds, with a light cross-offshore wind making it clean. Energy is moderate at 291, and it’s a fairly exposed beach/jetty—fine for intermediates. Water temp is about average for the time of year.
Monday and Tuesday stay small, around 3ft or less. Tuesday morning the 15th has a clean feel with a 3ft E swell (8 sec, 177 energy) and light cross-offshore, but it’s nothing special. Thursday the 17th morning is glassy with a tiny 2ft E swell (9 sec, 132 energy), so if you want a glassy knee-high wave, go then.
Then it goes flat from Friday the 18th through Monday the 21st—all under 3ft with energy dropping as low as 49. Not worth suiting up.
Things perk up Tuesday the 22nd. Onshore flow from the west, clean, and a 3ft SE groundswell arrives with a 11-second period—that’s a step up. Energy is 251 to 246, moderate. Wednesday the 23rd stays clean with offshore winds and a 2ft, 11-second SE swell (energy 136), still small but tidy.
The standout moment is Thursday the 24th afternoon—swell jumps to 5ft from SSE with a 10-second period and energy hits 690. That’s strong energy for this spot. But wind is cross-onshore, so it’ll be bumpy. If you’re kiting, that’s your window.
Best true surf comes Friday the 25th morning. Clean, light cross-offshore wind, a 3ft SE groundswell with a long 13-second period, and energy at 307. That’s a quality combo—long-period groundswell, clean conditions, and decent shape. Crowds are possible here sometimes, so expect company.
Saturday the 26th and Sunday the 27th mornings are glassy or clean, but swell drops to 2–2ft with long periods (12–13 sec). Energy is moderate (195 to 183). It’s surfable but ordinary—good for a longboard or foil.
Bottom line: Friday morning the 25th is the pick. The swell direction (SE) fits the spot’s optimum (SSE), wind is offshore, period is long, and energy is solid. Second pick is Sunday the 13th morning if you can’t wait, but it’s smaller.
Rusty out.
