Mawi Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s break down what’s coming for this stretch. It’s a real mixed deal, but there’s a couple of days that’ll make the hardcores grin.

We’ve got a steady run of southwest groundswell aimed at Mawi – that’s a shallow reef break, experts only. It breaks fairly regularly and the swell direction (SW / SSW) is exactly what it wants. Water temp is right where it should be for this time of year at 80°, nothing weird there.

First few days – Wednesday 2nd to Friday 4th – the surf is there but don’t bother. Swell runs from 5ft to 7ft, but the wind is a stiff cross-off at 15–16 mph from the SE. The forecast says marginal. Combined energy is moderate to strong (813 to 2442), but the quality is poor. Sit these out.

Saturday 5th and Sunday 6th get a little better. You’ve got 6ft to 7ft of SSW swell, period at 16 seconds – proper groundswell. Winds are still cross-off, 12–16 mph, but clean. Energy is strong (1766 to 2415). Not a standout yet, just getting warm.

Monday 7th bumps up to 8ft from the SSW, period 14 seconds, and wind drops to a lighter 9 mph from the SSE – still cross-off, but easier. Energy is strong at 2228. Getting closer.

The real highlight pops on Tuesday 8th September. Morning has a smaller 5ft swell but the period hits 19 seconds – that’s a very long period groundswell. Energy is very strong (3196). Then the afternoon turns on: 10ft of SSW swell at 18 seconds, energy a massive 5092. Wind is cross-off at 12 mph, clean. At 10ft this is expert territory only on a reef. The long period will make these waves unload hard. Best day of the whole run for those who can handle it. Expect some company – Mawi gets people sometimes.

Wednesday 9th through Friday 11th backs off to 6ft–8ft, periods 15–16 seconds, still clean but not as exciting. Energy stays strong.

Then Saturday 12th September brings 6ft SW swell at 15–16 seconds, energy spiking to 3042 and 3375. Clean cross-off wind. A solid session.

But the next real standout is Sunday 13th September. Morning has 10ft of SW swell at 18 seconds – energy a huge 5896. Afternoon holds at 10ft, period 17 seconds, energy 5018. Wind picks up to 19 mph from the SE, still cross-off. This is another experts-only day. Expect big, heavy reef waves. Crowds are likely.

Monday 14th and Tuesday 15th drop to 6ft–7ft, still clean, a quiet patch.

Then we finish with Wednesday 16th and Thursday 17th September. Steady 8ft to 10ft of SSW swell, period 16 seconds, energy in the 3236 to 4200 range. Clean cross-off wind at 12 mph. Again, big and powerful – experts only at this reef. Crowds possible.

If you’re not an advanced surfer, this whole 16-day run is pretty much a no-go. Too heavy and too big.

The days to mark on the calendar are Tuesday 8th and Sunday 13th – those are the ones with real firepower.

Rusty.
