The Lowdown
Alright, Rusty here again. Let’s break down Molhes de Mampituba in feet and Fahrenheit.
First thing – the water is sitting at 58°, which is a solid 5° colder than normal for this time of year. That’s a serious bite, so a thick wetsuit is non-negotiable.
The start is a slow build. Wednesday the 15th brings a clean 4ft swell from the SE, with a 9-second period and light offshore winds from the north. The combined energy is moderate at 363. Small, clean, but nothing to get excited about. It drops off by the afternoon.
Thursday the 16th morning shows the first real option. A 6ft swell from the NE, but with a short 7-second period – that’s wind swell, so it’ll be a bit jumbled. The energy is up to 531, and with a light north breeze it’s cross-offshore and clean. Surfable, but not the best shape.
Circle Saturday the 18th morning. That’s the standout. A clean 7ft of ENE swell with a 9-second period, and the combined energy hits 1083 – that’s strong. The wind is a gentle NNE cross-offshore, keeping it glassy. This is excellent surf, but at 7ft, it’s for experienced surfers only. The jetties will focus the energy.
Sunday the 19th morning is smaller again at 5ft, with a light north breeze making it clean. A nice, easy session. Monday the 20th morning is a gem – glassy conditions with a barely-there NNE breeze, and a clean 4ft from the ENE. Perfect for a quiet session.
The second week gets mixed. Tuesday the 22nd sees a south swell, with a 3ft morning set and a 10-second period. The wind is offshore from the NNW, keeping it clean. Wednesday the 23rd morning is 3ft from the SSE with a light offshore NW wind – tidy.
The long-range promise is Tuesday the 28th. A clean 5ft swell from the SSE with a very long 12-second period, and a light NNE cross-offshore breeze. The energy is 681. That’s a groundswell with real power, working well on the river mouth. The morning window is the one to aim for.
Watch out for Saturday the 26th. The swell hits 8ft with a moderate 8-second period, but the wind is a messy cross-shore from the SW. The energy is a massive 1288, but it’s going to be choppy and ugly. That one is better suited for the kite surfers unless you’re a seasoned charger.
Rusty.
