Diamond Beach Surf Forecast and Surf Report

Alright, Rusty here again. Let’s be straight with you—this stretch of days ahead is a tough one for paddlers. I’ve been lookin’ at Diamond Beach, and for the whole 16-day window, we’re in a real flat spell.

Overall Pattern

Right off the bat, we’ve got nothing on offer. The first record kicks off on Sunday, September 6th, and it’s a sad story from there. The whole forecast period is just a long gap of poor surf conditions. We’re lookin’ at a solid 16 days with no real recommendations. The tiny bits of energy that show up are weak—combined energy sittin’ between 8 and 88 (that’s low, folks). The swell heights barely get over 3 ft, and when they do, the wind is a mess. For most of this time, the waves are small, choppy, and crossed-up.

Diamond Beach

Now, let’s talk about the only spot we’ve got. Diamond Beach is an exposed, east-facing setup, and it’s best with a SE swell. The water temperature is a wild one: it’s 77°F, which is a whopping 6°F warmer than normal for this time of year. That’s very unusual—you’d be sweating in a spring suit, that’s for sure.

The first few days are a write-off. Sunday afternoon, September 6th, we’ve got a tiny 1 ft E swell with a 7-second period, all messed up by a cross-on E wind at 9 mph. Combined energy is only 14. Not worth paddlin’ out.

Monday, September 7th, is a slightly better story for the morning—clear skies, a light NE cross breeze at 6 mph, but the swell is still 1 ft from the east with a 7-second period. Combined energy at 19. It’s not breaking. The afternoon sees a 1 ft E swell with a slightly longer 10-second period, but the wind goes cross-on from the south at 6 mph. Again, poor.

Tuesday, September 8th, is a tease. The morning has a clean offshore wind from the WNW at 6 mph, but the swell is a pathetic 0.7 ft from the east. Combined energy of 9. The afternoon stays clean with a light cross-off wind, but same tiny swell. It’s glassy, but there’s nothing to ride.

We get a little bump mid-week. Wednesday, September 9th, the morning sees a 2 ft SSW swell, but it’s a 4-second period (that’s short-period wind slop) and a moderate cross-shore wind at 16 mph. Combined energy of 20. The afternoon gets a bit bigger—3 ft S swell, still a 4-second period, but now a fresh cross-on wind at 19 mph. Lumpy and messy. Not your day.

Thursday, September 10th, is the best of the worst. The morning has a clean cross-off wind from the WSW at 16 mph, with a 4 ft SSW swell and a 5-second period. Combined energy of 88. It’s the highest energy we see, but it’s still short-period, bumpy, and poorly shaped. The afternoon gets a clean offshore wind from the NW at 9 mph, with a 3 ft S swell and a 6-second period. Combined energy of 44. It’s clean, but it’s tiny. If you’re desperate and on a longboard, maybe, but I wouldn’t rush.

After that, Friday September 11th through to the end of the window on September 21st, it’s a grind. Tiny swells, mostly 0.3 ft to 1 ft, with a mix of cross and onshore winds. The only notable thing is that on Thursday, September 17th, we get a glassy afternoon with a 0.3 ft SE swell and a 12-second period, combined energy of 11. That’s a long-period groundswell, but there’s zero power behind it. By Monday, September 21st, we get a fresh offshore wind from the NW at 19 mph, but the swell is only 0.7 ft from the ESE with an 8-second period. Clean, but flat.

The Bottom Line

Look, folks, this is a blank run. We’ve got one break, and it’s almost never got enough energy or clean wind at the same time. The consistency is lackin’, and the forecasts could change, but right now, the setup looks way more interesting for kite surfing than for paddle surfing when the wind picks up—especially on days like Wednesday, September 9th and Sunday, September 20th, when we’ve got 3 ft+ of lumpy, cross-on chop.

There’s no standout here. No best on offer. Just a 16-day stretch of poor conditions. Stash the board, wax a different hobby, and wait for the next swell.

Rusty.
