Nine Mile Reef Surf Forecast and Surf Report

Alright, let’s break it down. For the next 16 days, we’ve got a mixed bag at Nine Mile Reef – a reef setup that’s exposed to the swell. Things start off rough, build to a real standout morning on Thursday the 20th, then quieten down before another promising window shows up in early September.

Right now, we’re in a bit of a flat patch. The morning of Wednesday the 19th has 6 ft swell from the SSW, but the wind is onshore at 9 mph and the conditions are poor – not worth paddling out for. That onshore wind sticks around through the afternoon with 5 ft, and it’s marginal at best.

Thursday the 20th is the clear highlight of the first week. The morning brings a solid 8 ft of SSW groundswell with a long 13-second period, and the wind is light at 6 mph but still onshore. The combined energy is strong at 1807 – you’ll feel that push. But here’s the thing: the wave comment says it might actually be too big for this break. This is a beginner-friendly reef, and 8 ft is getting into expert territory. Still, if you’re looking for power, this is it. The afternoon drops off a bit with 7 ft and stronger onshore wind – not the time.

Friday the 21st is a step down. Morning has 5 ft and light wind, but the conditions are marginal. Afternoon sees the wind ease to almost nothing with 4 ft – still just marginal.

Saturday the 22nd brings a change. The morning has 3 ft of SSW swell but here’s the good part: the wind swings to the NNW at 12 mph, which is offshore. Combined energy is moderate at 440, and the wave comment says “expect good surf conditions.” It’s clean. The afternoon gets 5 ft with a cross-offshore breeze and “very good” conditions – that’s a solid window for a session, though the swell is a bit weaker in energy at 521.

Sunday the 23rd is back to onshore wind and marginal surf – 6 ft in the morning and 3 ft in the afternoon, but the wind is on it.

Monday the 24th is poor to marginal across the board with 4 ft swell. Tuesday the 25th is marginal with 5 ft and a cross-onshore wind that makes things choppy.

Now, Wednesday the 26th is another little gem. The morning is glassy – wind from the NNW at just 3 mph, totally calm. The swell is 3 ft from the SW with a 12-second period, and the combined energy is 559. The wave comment says “expect very good surf conditions.” That’s clean, lined-up, and relaxed. The afternoon is lighter at 3 ft and cross-shore – fine but not as good.

Thursday the 27th morning has 2 ft with a moderate offshore wind – “good surf conditions” but small. Friday the 28th is onshore and poor again. Saturday the 29th gets bigger – 6 ft in the morning with a 15-second period, but onshore wind keeps it marginal. By afternoon, the wind ramps up to 19 mph cross-onshore and the swell hits 10 ft – that’s too big for beginners and messy for everyone. Sunday the 30th is strong cross-onshore wind, poor conditions across the board.

We then hit a lull from Sunday through Monday the 31st – poor conditions with strong wind and onshore flow. The energy drops right off.

Then we get a new pulse in early September. Tuesday the 1st has 5 ft from the SW with a 14-second period and a cross-offshore wind – clean conditions. The combined energy is 970 (moderate-strong). Wednesday the 2nd is even better: 5 ft from the SW, 13-second period, clean with a cross-offshore breeze. The wave comment rates it “very good” and the energy is 760. That’s a solid session.

Finally, Thursday the 3rd brings a massive 20 ft swell from the WSW with a 14-second period and light offshore wind – combined energy of 18536. But again, this is way too big for Nine Mile Reef – expert only, and even then, it’s wild. The water temperature is pretty average for this time of year – nothing unusual going on.

My pick for the standout? Thursday morning the 20th if you’re an experienced surfer and can handle the size – that’s the biggest, most powerful swell of the window. For the cleaner, more relaxed sessions, Saturday the 22nd and Wednesday the 26th are your best bets with offshore or glassy conditions. The early September window on Wednesday the 2nd is a promising one, too – just a bit further out, so keep an eye on it.
