Diamond Beach Surf Forecast and Surf Report

G’day, Rusty here. Let’s be straight with you: this stretch from Monday 6 July through to Tuesday 21 July is looking like a tough run for Diamond Beach. The entire 16-day window is a flat spell with tiny, weak swell and poor conditions. There are no standout sessions, no hidden gems, just a whole lot of waiting.

The first recommended surf shows up right at the start, but it’s a dud. Monday morning, 6 July, offers a tiny 2 ft southerly swell with a short period of only 4 seconds. The swell energy is weak at just 18. Wind is cross-onshore from the SSE at 9 mph, so it’s choppy and messy. The water temperature is 76°F, which is much warmer than normal for this time of year, sitting 5°F above average—pretty unusual. But that doesn’t help the surf.

Monday afternoon stays the same: 2 ft from the SSE, 4-second period, cross-onshore wind, still poor.

Tuesday 7 July starts with a glassy morning—wind is calm, 0 mph—but the swell drops to 1 ft from the ENE, period 6 seconds, energy only 25. It’s flat. Afternoon picks up a cross-shore wind from the ENE at 12 mph, swell up to 1 ft from the SE with a 10-second period, energy 38. Still, the wave comment says “poor surf conditions.” Not worth a paddle.

Wednesday 8 July brings a bit of hope but it’s short-lived. The morning shows 3 ft from the ENE, 6-second period, energy 71, with a gentle cross-shore breeze. The afternoon clears up with a 3 ft easterly swell, 6-second period, energy 65, and onshore wind from the SE at 6 mph. Both sessions are rated poor—the swell is too weak and short-period for any decent shape.

Thursday 9 July is back to 2 ft from the east, 7-second period, choppy with a cross-onshore SSE wind at 9 mph in the morning, then afternoon wind picks up to 16 mph from the SSE with 2 ft swell, period 8 seconds, energy 59. Still poor.

Friday 10 July offers a clean morning with cross-offshore wind from the west at 9 mph, but the swell is a pathetic 0.7 ft from the ESE, period 10 seconds, energy 19. Same story in the afternoon: 0.7 ft, 10-second period, energy 17, clean but flat.

Saturday 11 July has a morning offshore wind from the WNW at 9 mph, tiny 1 ft from the SSE, period 7 seconds, energy 13. Clean, but you’d be surfing ripples. Afternoon turns cross-onshore, same tiny swell.

Sunday 12 July sees a slight bump: afternoon swell reaches 4 ft from the SE, period 5 seconds, energy 93—the highest in the whole window. But it’s onshore from the SE at 12 mph, making for lumpy, messy waves. Still rated poor.

Monday 13 July morning has a strong cross-offshore NNE wind at 25 mph, clean conditions, but only 2 ft from the SE, period 7 seconds, energy 53. The wind is too strong for comfortable paddling. Afternoon is cross-shore, 2 ft.

The rest of the run through to Tuesday 21 July is all tiny swell—1 ft to 3 ft—with short periods, weak energy (mostly in the teens or twenties), and a mix of cross-on, onshore, or offshore winds. Nothing breaks the pattern of poor surf.

The standout? Genuinely, there isn’t one. The closest thing to a “best” session is Wednesday 8 July morning with a 3 ft ENE swell and gentle cross-shore wind—but the 6-second period and low energy mean it’s barely rideable. For beginners, this swell is under 5 ft, so it’s not too big, but the quality is so lacking it’s not worth the drive. Crowds at Diamond Beach are listed as “sometimes,” so you might have it to yourself, but that’s because there’s nothing to surf.

Given the near-constant poor ratings and tiny energy (mostly below 100), this is a blank run. For an exposed spot like Diamond Beach, a gap like this is more normal for the area—forecasts can change, but right now it’s a waiting game.

If you’re kiting, the windier afternoons—like 13 July with 25 mph cross-offshore—might be worth a look, but for paddle surfing, save your energy.

Rusty.
