Diamond Beach Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a proper look at what Diamond Beach has cookin’ for us over the next couple of weeks. I’ll be straight with ya – it’s a long, flat spell for the most part, but there’s a little blip of hope if you’ve got patience and a board for bigger, cleaner stuff.

Right now and for the next week or more, Diamond Beach is pretty much a write-off for a decent paddle. We’re talkin’ days of tiny, weak, and messy surf – starting Monday the 6th through to Sunday the 12th, you’ll be lookin’ at waves mostly under 3 ft, with short, weak periods and mostly cross-onshore or choppy wind. The combined energy barely climbs past 70 (weak), so it’s barely got any push. Not worth wetting the suit for. There’s a brief moment Saturday morning the 11th with glassy conditions and a tiny 1.0 ft swell, but the period’s a low 5 seconds – just not enough to ride.

The standout window finally appears on Monday morning, 13th July. The swell jumps to 6 ft from the east with a period of 7 seconds, and the combined energy hits 295 (moderate). The wind’s a light north cross-off, so it should be clean. That wave comment says “expect good surf conditions,” so my gut says get out there early. The water’s sitting at a very warm 76°F, which is a massive 5°F warmer than usual for this time of year – you’ll be sweating in your wettie. The break is exposed to southeast swell, and we’ve got east swell hitting it, which is off the optimum direction but the size and clean conditions make it the pick of the entire period. Keep in mind Diamond Beach can be inconsistent, and it’s a beginner-friendly spot – this 6 ft might be a little big for total beginners, but for most of ya, it’s fine.

Tuesday morning the 14th is the real heavy hitter for experienced surfers only. The swell jumps to 7 ft from the east, period 9 seconds, and the combined energy absolutely hammers in at 1029 (strong to very strong). Wind is west-southwest cross-off, so glassy clean conditions. This is solid, powerful groundswell – but at over 8 ft, it’s expert territory. The wave comment says “excellent surf conditions for experienced surfers”, so if you’ve got the skills, this is your session. Just be aware that with this much east swell on an exposed beach, it’ll be a ripping paddle and you’ll want to pick your peak carefully. Crowds are possible here sometimes, so expect company if it’s firing.

After that Tuesday morning pulse, it fades fast – Tuesday afternoon drops to 4 ft with cross-on wind and shoddy quality. From Wednesday the 15th onward, we’re back to tiny, weak dribble for the rest of the 16 days – mostly under 2 ft, with combined energy dropping below 100, and wind often clean but just no size to work with. There’s a brief moment on Sunday the 19th morning with 2 ft and clean offshore breeze, but it’s still too small to get excited about.

So here’s the deal: the best on offer is Monday morning the 13th for a fun, clean session on a decent 6 ft east swell, and Tuesday morning the 14th for the big dogs who want a powerful 7 ft east swell with glassy conditions. Everything else is flat and quiet. Don’t hold your breath for the second week – it’s a long run of small stuff.

Stay stoked, check the tides, and don’t paddle out alone on that Tuesday morning if you’re not ready for it.

Rusty.
