The Lowdown
G’day, I’m Rusty, and I’ve been eyeballin’ the next 16 days of surf for Atalaia (Molhes). There’s a bit of a dry spell to start, but you won’t have to wait long – the first real surf shows up on Monday the 14th.
Monday the 14th, we get a 1.4m (5ft) swell from the SSE, period around 8 seconds, with a light cross-offshore wind from the SSW at 10 km/h (6 mph). The water temp is 19° (67°F), normal for the season. The combined energy is 346, moderate, and the waves are clean. By the afternoon it drops to 1.2m (4ft) and gets just okay.
Tuesday the 15th, small stuff – 0.7m (2ft) from the SE in the morning, period 8 seconds, but the wind goes glassy out of the WSW at 5 km/h (3 mph). Energy’s only 140, weak. It’s clean but tiny. The arvo turns onshore and turns to junk.
Wednesday the 16th, we bounce back a bit – 1.2m (4ft) from the SSE, period 10 seconds, energy 458 (moderate). The wind’s a cross-onshore, so not perfect. It’s marginal. The next few days are messy with onshore breezes and small waves.
Now, the big one. Sunday the 20th morning – solid 2.5m (8ft) from the ENE, period 9 seconds, with a cross-offshore wind from the NNW at 10 km/h (6 mph). The combined energy is a massive 1754 (strong). This is the standout, but at 2.5m (8ft), it’s for experts only. The ENE direction lines up well with what this break likes, and that period will feel like real groundswell – best on the jetty. Crowds can show up sometimes, so be early.
Monday the 21st morning brings 1.6m (5ft) from the E, period 9 seconds, with offshore wind from the W at 5 km/h (3 mph) – clean as. Energy is 432 (moderate). This is the best bet for most, with good shape and no wind chop.
From Tuesday the 22nd, it’s downhill. Swell drops to 1.1m (4ft) and smaller, with mix of cross-offshore and onshore winds. The last week – 24th to 29th – is flat, with waves under 0.8m (3ft) and weak energy down to double digits. The odd glassy morning but no real punch.
Bottom line: Sunday the 20th morning is the big guns – 2.5m (8ft) and clean, but hold onto your board. Monday the 21st morning is the sweet spot for most of us at 1.6m (5ft) and offshore. After that, it’s small and quiet. Water temp’s average, and the jetty handles the longer-period swell nicely. Get it while you can.
