Diamond Beach Surf Forecast and Surf Report

Alright, let me break down what we’ve got here for Diamond Beach. Straight up, this isn’t a classic run – the surf is tiny for most of the next two weeks. We’re looking at a lot of flat spells with barely a ripple. The first proper chance to even think about a wave doesn’t show up until Monday the 31st of August, and even then, it’s not what you’d call pumping. There’s a long stretch of almost nothing from now until then.

So, Sunday the 23rd of August through to Sunday the 30th – forget it. We’re talking swell heights from 0.7 ft to 2 ft, periods all over the shop, and generally poor conditions. The combined swell energy is weak, mostly in the teens and thirties, like 17 or 34 – just not enough push. Winds are cross-off or glassy at times, but there’s simply no swell to work with. The water temp is sitting at a warm 77° on Sunday morning, which is a touch warmer than normal for this time of year, so at least it’s nice to be in the water even if you’re just floating.

Now, Monday the 31st of August finally brings a pulse. The morning session shows a 1.0 ft swell from the SE with a long 18-second period. That’s proper groundswell energy, and the combined energy jumps to 65 – still on the weaker side, but it’s something. Winds are light and cross-off from the WNW, so it’ll be clean. This swell is best for a point or reef setup because that long period can make a beach break close out. But for Diamond Beach being an exposed SE spot, it might offer some fun little runners if you’re patient. That Monday afternoon gets a bit more size – 3 ft from the SSE, with a 17-second period and a combined energy of 464, which is moderate. But there’s a risk of thunderstorms and cross-onshore wind, so it’s not the pick of the window.

The real standout, the one to circle on the calendar, is Friday the 4th of September. Friday morning looks clean with a light offshore from the NW, 2 ft from the SE at 12 seconds, and energy hitting 254. But the afternoon is where it’s at: 3 ft from the SE, 12-second period, combined energy of 368, and light cross-off winds from the WSW. This is the best combo in the whole 16-day run – decent chest-high waves with clean conditions. It’s still small to moderate, but for this stretch, that’s the gold. Saturday the 5th of September morning builds a bit to 4 ft from the ESE, but winds turn cross-on and it gets choppy, so Friday afternoon is your window.

Later on, Thursday the 3rd of September afternoon shows some promise with 2 ft from the SE at 13 seconds and offshore winds from the WNW, energy at 182, but it’s not as good as Friday. Everything after the 5th drops right back off into tiny wind-affected slop.

Bottom line: if you’ve got a longboard and patience, the 31st of August morning might give you a glassy but small ride. The true standout is Friday the 4th of September afternoon – that’s your best shot at a proper session. Crowds are listed as "sometimes" here, so you might have some company on that Friday, but it’s not as bad as a full-on peak. For beginners, that 3 ft swell is fine, but the 4 ft on Saturday starts getting a little more challenging and the period is dropping. As for the second week, the first few days of September offer a flicker, but it’s pretty bleak after the 6th.

Stay hopeful, though – forecasts can change. But right now, wait for that Friday afternoon.
