Diamond Beach Surf Forecast and Surf Report

Alright, I’m looking at this forecast for Diamond Beach and honestly, it's been a rough run for the first week. The water temp is sitting at 73°F, which feels a touch warmer than usual for July here—like the ocean’s having an off-season summer vibe.

First thing, there's virtually nothing on the table for the opening days. The first record we get is for Friday, July 3rd, but wave heights are barely 0.7ft to 1ft, with poor conditions and cross-off or onshore breezes. The energy is weak, sitting around 17 to 27 (combined swell energy). Not worth paddling out.

Saturday the 4th is more of the same: tiny swell around 1.0ft, and those morning winds are light cross-off (clean looking), but the afternoon gets wrecked by a moderate cross-onshore from the south at 16 mph. Same story for Sunday the 5th—morning sees glassy conditions with 1.0ft SE swell, but it's so weak (12 energy), you'd be bobbing more than riding. The arvo gets a risk of thunderstorms and onshore wind. No go.

Monday the 6th through to Thursday the 9th is pretty much a write-off. Tiny swell, mostly cross-onshore or onshore wind, and energy values barely creeping past 50 or 60. It’s not surfable in a meaningful way.

We finally see a small pulse of hope on Friday, July 10th. The morning has 2ft from the south, with a clean cross-off breeze from the WNW (9 mph). It’s still poor conditions overall though, and the afternoon jumps up to 3ft S swell, but with a really short period of 4 seconds and an offshore wind. That’s about as messy as it sounds—forced, weak lines. Not recommended.

Saturday, July 11th morning is the first time we get a “surfable” nod—2ft SSE swell with a clean, light cross-off. Energy is 82—still moderate, but at least there’s a sniff of quality. The crowd factor is listed as "sometimes," so it might be worth a paddle if you’re desperate. But honestly, the waves are ordinary.

The real standout here is late in the second week. Mark your calendar for Saturday, July 18th. Morning sees 3ft from the SSE, combined with a clean offshore breeze from the WNW at 16 mph, producing moderate offshore and clean waves. Energy hits 87. It’s not massive, but given the weeks of tiny, choppy junk, this is the best window—small but clean lines, and the offshore wind will groom it. It’s still only a beginner-friendly break and is inconsistent, so you’ll have to be patient between sets. The swell direction from the SSE is a reasonable match for Diamond Beach’s exposure.

The afternoon of the 18th drops off again to 2ft, so don’t sleep in—hit it early.

Overall, this is a stretch of mostly flat or poor surf, with the only real recommendable session being the morning of July 18th. The rest of the time you’re looking at tiny wavelets, onshore mess, or not enough energy to bother. It’s one of those runs where the ocean’s taking a holiday, and so should you.
