Matinhos Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ve been staring at the charts for Matinhos and I gotta be straight with you – the next 16 days are a real mixed bag, with plenty of flat spells and ordinary conditions. But there’s a couple of windows that’ll get your heart pumping if you’re patient and pick your sessions right.

We kick off Monday the 7th with small, marginal surf. A 5ft SSE swell rolls in for the morning, but it's coming from the SW at 9 mph, cross-shore, and the energy reading is a moderate 365. The water’s a balmy 70° with a positive anomaly of 4°, so much warmer than normal for this time of year – that’s a nice touch. Still, the wind and chop keep things messy, scoring poorly. Through Tuesday and into Wednesday the 9th, the swell drops right off, down to 3ft. There’s a glimmer on Wednesday morning though – glassy conditions with a 3ft E swell and a period of 8 seconds. The energy’s moderate at 193, but it’s small and ordinary. Thursday the 10th morning brings a clean 3ft E swell with NNW winds 9 mph, cross-offshore. The energy reading is just 138, weak. Still, it’s a tidy little wave for a cruise. Friday the 11th morning is glassy again, 3ft E swell, energy down to 131. It’s small but clean.

Then, from Saturday the 12th, we hit a real slump. The swell drops to 2ft with onshore winds, and the energy plummets to 80 and 85. That’s weak, poor conditions. Sunday the 13th sees a sudden spike: a 6ft SSE swell arrives with a period of 13 seconds, and the energy jumps to a massive 1338, strong. But the wind is straight onshore at 12 mph, and it’s classed as poor. What a tease. That onshore wind will shred any shape.

Now, here’s the standout. Monday the 14th of September – this is the one. The morning brings a solid 7ft ESE groundswell with a period of 12 seconds. The combined energy is a powerful 2038, very strong. The wind is light from the N at 6 mph, cross-offshore, keeping things clean. This is excellent surf for experienced surfers. The wave height is over 5ft and pushing 8ft, so this is for the experienced crew only. The direction (ESE) is a solid match for Matinhos’s optimum S swell, but the cross-off wind will make the point break work beautifully. Expect long, powerful lines. Afternoon stays clean with a 7ft E swell, energy 1123. This is your best window.

After that, it drops. Tuesday the 15th sees small, poor surf. On Wednesday the 16th, a 5ft SSE swell with 9-second period rolls in, energy 539, but it’s onshore and marginal. The gap continues through Thursday and Friday the 18th, where we see a 5ft SSE swell with a period of 14 seconds and strong energy of 984 – but the wind is cross-onshore, making it choppy. Saturday the 19th morning is clean again with a small 3ft SSE swell, period 13 seconds, energy 278. Light offshore winds. It’s a nice little reprieve.

Finally, Sunday the 20th of September shapes up as another highlight. The morning is glassy with a 6ft E swell, period 7 seconds, energy 359. That’s short period but clean. The afternoon holds a 6ft E swell, period 8 seconds, energy 390, with light N winds cross-offshore. The wave size is over 5ft, so it’s for intermediate to advanced surfers. Clean conditions will make these waves fun.

The rest of the run from Monday the 21st onwards is small, onshore, and poor. The last Tuesday the 22nd morning is clean but tiny at 4ft, energy down to 187.

So, to sum it up: the best on offer is Monday the 14th – that 7ft ESE groundswell with clean, light offshore winds is your ticket. Second best is Sunday the 20th, with clean, glassy conditions and solid 6ft to 6ft E swell. Everything else is small, choppy, or too week-long to get excited about. The water is much warmer than average, so at least you won’t need a thick suit. Keep it on your radar, and don’t be afraid to wait for those two windows.

Rusty.
