The Lowdown
G’day, Rusty here. Let’s break down what’s heading our way.
Right now, Molhes de Mampituba is pretty quiet. Wednesday afternoon offers a small 0.7m SSE swell with glassy wind, but it’s weak – nothing to rush out for.
Thursday stays small and ordinary. Friday morning is clean but tiny. Friday afternoon kicks up a 2.2m SSW swell, but 25 km/h cross wind makes it choppy – better for kite gear than a paddle board.
Saturday the 8th is the first proper call. Saturday morning has a 2.0m SSE swell with a long 13-second period and clean cross-off wind – good solid energy. Saturday afternoon is even better: glassy conditions, 1.8m SSE swell at 12 seconds, and strong energy – excellent for experienced surfers. The river mouth and jetties will be handling that well.
Sunday is messy, but Monday the 10th morning is clean with 1.4m S swell at 12 seconds – very good. Tuesday the 11th morning is another standout: 2.0m SSE swell at 12 seconds, clean cross-off wind – excellent for experienced surfers.
Wednesday the 12th morning stays very good with 1.6m SSE swell and glassy cross-off wind. The second week keeps some size but the wind turns lumpy at times. By the 15th and 16th, the swell builds again – Saturday the 15th has a 1.6m SSE swell with a very long 15-second period, but strong NE winds rough it up. Sunday the 16th has 2.3m E swell, short period, with wind.
Monday the 17th morning hits 3.0m from the ENE – too big for this break. Tuesday the 18th morning settles to a glassy 1.5m E swell with good energy – clean and surfable. Wednesday the 19th and Thursday the 20th taper off but stay clean on the mornings.
Best bets: Saturday afternoon the 8th and Tuesday morning the 11th – clean winds, solid SSE groundswell, excellent conditions for experienced surfers.
Rusty.
