Diamond Beach Surf Forecast and Surf Report

Alright, let’s get into it. Rusty here.

First up, the overall pattern for Diamond Beach: honest truth, it’s a quiet stretch ahead. The swell stays small throughout the whole 16-day run, and the wind isn’t doing us many favours either. We’ve got a bit of a rough start with no real surf on offer for the first couple of days, and it’s going to stay marginal at best through the whole period. There’s a solid gap of days with nothing worth paddling out for.

The water’s sitting at a warm 77° at the start, which is much warmer than usual for this time of year, so that’s something to note if you’re going for a swim.

Tuesday afternoon (September 1st) kicks things off with a tiny 2 ft SSE swell, but it’s cross-on from the south at 9 mph and the combined energy is weak at just 51. Waves are choppy and messy. Not worth suiting up.

Wednesday (2nd) stays poor. The morning shows 2 ft SE swell with a moderate cross-shore wind at 16 mph, and the afternoon goes cross-on with 3 ft from the ENE. Both are choppy, and the combined energy is only moderate at 100. No go.

Thursday (3rd) morning is still poor with 1 ft SE swell and cross-on wind. But the afternoon brings a shift: wind goes light cross-off from the west at just 3 mph, clean conditions, but the swell is still tiny at 1 ft and energy is only 39. You might get a knee-high ripple if you’re desperate.

Friday (4th) is clean with offshore winds from the WNW to NW, but the swell is only 1 ft. Combined energy is 18-19. It’s glassy-looking but flat.

Saturday (5th) and Sunday (6th) stay the same story: small, clean, but essentially flat. No real push.

Monday (7th) afternoon shows a little bump: 3 ft from the south, but the period is a short 4 seconds and it’s cross-on at 12 mph. Combined energy hits 62, but it’s choppy and weak. Still poor.

The rest of the week into the second week keeps the same vibe. Tiny swell, mostly under 2 ft, with occasional cleaner moments but nothing that breaks properly. The best looking conditions for just a clean surface come on the 9th (Wednesday) with offshore NNW wind and 1 ft SE swell – but that’s barely a ripple.

By the second week, from September 10th onward, there are a few afternoons with clean offshore wind and small swell, like the 10th afternoon with 4 ft from the south and a short period of 5 seconds, but the combined energy is only 53 and the wave shape will be poor. Not worth chasing.

The 15th (Tuesday) and 16th (Wednesday) see a tiny uptick to 2 ft from the ENE, but winds turn cross or cross-on, and the period is short at 6-7 seconds. Still no quality on offer.

Bottom line: Diamond Beach is a no-go for any real surfing in this outlook. The swell is too small, too weak, and the wind often messes it up. This spot is exposed to the SE, but the optimum swell direction is SE and we just aren’t getting any decent energy. The break is inconsistent and best for beginners when it’s working, but right now it’s just not working. If you’re keen on being in the water, it’s more of a flat day paddle than a surf session. For the few clean moments with offshore wind, you’d be lucky to find a ripple.

Rusty out.
