The Lowdown
Alright, Rusty here. Let’s break down what’s coming.
The first few days are pretty slow – small swell, messy winds, nothing to get excited about. Water temp is around 68°F, which is a touch warmer than normal for this time of year.
Sunday the 6th is a washout – 2ft from the SSE with a 6 second period and cross wind, combined energy only 70 – weak. Monday the 7th morning has 5ft from the SSE, 10 second period, but it’s cross and energy is 620 – still not clean enough. Tuesday the 8th morning is clean with a light cross-off breeze, but the swell is tiny at 2ft from the SE. Tuesday afternoon goes glassy with 4ft from the east, energy 149 – weak. Wednesday the 9th morning is clean with 4ft east swell, 8 seconds, energy 221 – surfable but ordinary.
Thursday the 10th afternoon is a little better – glassy, 3ft from the ENE, 8 seconds, energy 290 – moderate. Expect good surf conditions. A log would be perfect.
Friday the 11th morning is glassy with 2ft east swell, but energy drops to 93. Saturday the 12th morning is glassy with 3ft from the ENE, energy 83 – weak.
Sunday the 13th is a mess. Swell builds to 5ft from the SE with 10 seconds, but it’s cross-on and choppy, energy 404. Afternoon jumps to 10ft from the SE with 10 seconds and massive energy of 2539 (very strong), but still cross-on and choppy. Atalaia (Molhes) is a beach and jetty setup, so with that wind and size, it’s more of a kite day than a paddle day.
Monday the 14th afternoon is the best bet. Clean with a light cross-off breeze from the NNW, 6ft from the ESE, 10 seconds, energy 756 – moderate to strong. Expect very good surf conditions. Swell direction is close to the optimum SSE, and the size is solid. This is the one to target.
Tuesday the 15th morning is still clean with 4ft from the ESE, but it’s ordinary.
Wednesday the 16th through Friday the 18th are mostly poor – small swell, cross-on winds. Friday the 18th has a 13 second period from the SE but the swell is only 2-2ft and the wind is cross-on – not worth it.
Saturday the 19th is the second highlight. Morning is glassy with 5ft from the ENE, 8 seconds, energy 570 – moderate. Afternoon goes glassy calm with 6ft from the ENE, 8 seconds, energy 781 – moderate to strong. Expect very good surf conditions both sessions. Clean, fun-sized waves all day.
Sunday the 20th and Monday the 21st fade back to marginal or poor conditions.
Bottom line: Monday the 14th afternoon and Saturday the 19th all day are the standouts. The 14th has better swell direction and size, the 19th has glassy conditions and solid 5-6ft. The rest is mostly filler.
