The Lowdown

Right then, let’s have a look at what’s shaping up for Molhes de Mampituba. The water’s sitting at 66°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus.

The start of the run is a bit of a write-off, I’m not gonna lie. Friday the 7th is pretty grim with a messy cross-shore wind and short, weak swell. The combined energy on Friday morning is just 93 (weak), and it’s not much better in the afternoon. You’d be better off staying home.

Things start to get interesting on Saturday the 8th. The morning sees a solid 6ft swell from the SSE with a long 14-second period, and the combined energy jumps right up to 1270 (strong). The wind is a gentle cross-offshore breeze, so the surf’s looking clean. This is for experienced surfers only though – that’s a fair bit of power. The afternoon holds up nicely too, with 5ft and clean conditions.

Sunday the 9th is a step down. The morning is cross-shore and messy on a 6ft S swell, and the afternoon gets blown out by a strong cross-onshore wind, so that’s a no-go.

Monday the 10th is a bit of a mixed bag. The morning has a gentle cross-shore flow and a 5ft S swell with a 12-second period, but it’s only marginal. The afternoon goes onshore and choppy again.

Now, here’s where it gets good. Tuesday the 11th morning is a standout. You’ve got 5ft of SSE swell, 12-second period, and a light offshore wind from the NNW. The combined energy is 782 (moderate), and the conditions are clean. This is a very good window for intermediate surfers. The afternoon is a little more cross-shore, but still alright.

Wednesday the 12th and Thursday the 13th mornings are both really clean with light cross-offshore winds and consistent 5ft to 5ft SSE swell. The energy is moderate, and the surf looks excellent for experienced intermediates.

Then, on Friday the 14th afternoon, we get a special moment. The wind drops to nothing – glassy conditions – on a 5ft SSE swell. That’s going to be a treat, with clean, lined-up waves.

The weekend of the 15th and 16th is poor again. Wind shifts onshore, swell drops, and it gets messy and lumpy. Not worth paddling out.

The following week, starting Monday the 17th, the swell picks up. The morning has 6ft from the ENE with a moderate cross-offshore breeze and clean faces. The energy is 1003 (strong). By Tuesday the 18th, the swell pumps up to 10ft from the east, with a 10-second period. The combined energy is massive: 1970 in the morning and 2107 in the afternoon. The wind is offshore and clean, but this is only for experts. That’s a serious amount of water moving. The break is a river/jetty setup, so those long-period groundswells might line up well, but it will be too big for most.

Wednesday the 19th is still big, with 8ft from the east, but the wind gets stronger. It’s clean, but it’s a strong breeze. Thursday the 20th morning is cleaner and smaller at 6ft, a good option for the experienced crew.

The best on offer is probably the Saturday morning the 8th for the combination of size and clean conditions, or the glassy Friday the 14th afternoon for a more relaxed session. Tuesday the 18th is a big-wave specialist’s dream, but it’s a warning call for everyone else.

Overall, it’s a pretty good run for the area, with a few flat days early on, but then a solid week of decent to excellent surf, especially for the more experienced surfer.

Rusty.
