Nine Mile Reef Surf Forecast and Surf Report

Alright, let’s break down the forecast for Nine Mile Reef.

The next few days are a bit mellow, but there’s a solid pulse building as we roll into early September. Thursday morning kicks off with some clouds and a light offshore breeze from the NNW, making for clean lines. Swell is 4 ft from the south at 11 seconds, with moderate energy at 555. The water temp is 59°, right around average for this time of year. A decent session, but beginners might find it a little punchy.

Friday morning, the wind goes dead calm, glassy, and the swell drops to 3 ft from the south, still 11 seconds, but energy is weaker at 322. Clean, but nothing to get fired up about. Then we hit a rough patch: Friday afternoon through Sunday is a write-off with onshore winds and rain, so save your energy.

Monday morning, August 31st, brings a window of clean surf again, with a cross-offshore breeze from the northwest and 4 ft south swell, energy at 309. Not big, but tidy. Then Tuesday morning, September 1st, things start to cook. The swell bumps up to 5 ft from the southwest, period 13 seconds, and energy climbs to 828. Offshore wind from the NNW keeps it clean. That’s a standout morning.

Tuesday afternoon, the same day, the swell pushes to 7 ft, still southwest, and energy surges to 1226. With a cross-offshore breeze from the northwest, it’s excellent conditions for experienced surfers. This is the best window of the whole forecast. The swell direction is SSE, which is the optimum for Nine Mile Reef, so it’s going to line up perfectly.

Wednesday morning, September 2nd, the swell hits 8 ft from the southwest at 14 seconds, and energy is massive at 2704. It’s clean, but this is big—only for experts. The wind is light and cross-offshore, but the size may push the reef’s limits. By Wednesday afternoon, the wind swings onshore and the swell jumps to 13 ft, so that’s a no-go.

From September 3rd through the 5th, it’s a rough stretch. Strong onshore winds, rain, and lumpy conditions. The swell hangs around 7 ft to 10 ft, but the wind is fresh and cross-shore, making it messy. Not worth the paddle.

Then Sunday morning, September 6th, things turn around. Glassy conditions, a 6 ft swell from the east-southeast, but the period is short at 6 seconds, and energy is 600. It’s clean and rideable, but that short period means choppy, less powerful waves. Still, a fun morning.

Monday, September 7th, offers clean surf again with a 5 ft swell from the southeast, 8-second period, and light offshore wind from the north-northeast. Energy at 436. Good for a session, but nothing massive.

After that, the forecast fades out. From September 8th onward, the swell drops to tiny 1.0 ft to 1 ft, and the wind turns onshore or cross-shore, so it’s flat and poor. There’s a spike in the swell on the 11th up to 8 ft, but the wind is strong and cross-on, so it’s blown out.

Overall, the standout is Tuesday afternoon, September 1st. That’s your best bet for a serious, high-quality session at Nine Mile Reef. The morning of the 1st is also good, but the afternoon is the real winner. The rest of the month is a mixed bag—some clean windows, but the big swells come with wind or size issues.
