The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window, but frankly, it’s a rough start. The first few days are a write-off for Dee Dees, so we’re looking at a gap of about 4 days before anything even remotely surfable shows up.
The real story at Dee Dees is a classic case of too much of a good thing. The first couple of days are a total mess. On Saturday, August 1st, we’ve got a massive 13ft to 15ft SSW swell, but with a strong cross-onshore wind, it’s just a lumpy, poor mess – not worth a paddle. Sunday the 2nd is a bit cleaner, but the swell is still too big at 7ft, and that’s for a reef break that likes it smaller. The theme continues through the middle of the week; a huge 15ft to 16ft S swell on Tuesday the 4th is pure chaos with strong winds.
The first real glimmer of hope, and honestly the standout of the whole outlook, is Thursday, August 6th. We get a window of glassy conditions. The morning sees a 5ft SSW swell with a light 5 km/h N wind – glassy. The afternoon cleans up even more with a 4ft SSE swell and glassy conditions again. The wave energy is moderate (930 and 709 respectively), but the clean conditions will make it feel better than the numbers suggest. This is a rare, calm moment, and I’d be stoked to be out there.
After that, the second week (from August 9th onward) gets iffy again. The swell drops right off, and by Monday the 10th, we’re looking at tiny 3ft leftovers. The water temperature is sitting at 54°F, which is pretty normal for this time of year, so no surprises there.
Later in the run, we see another spike on Friday, August 14th, with a 7ft S swell. The wind is light and offshore, but the period is a short 7 seconds. That’s windswell, not proper groundswell, so it’ll be weak and won’t wrap around the reef well. It’s a decent option for the desperate, but not the standout.
The very last day, Sunday, August 16th, has a glassy morning with a tiny 2ft SSW swell but a very long period of 16 seconds. That’s a long wait between sets, but it might be the cleanest little wave of the window if you’re patient.
So, for the best surf on offer, your one and only call is Thursday, August 6th at Dee Dees. It’s not big, but it’s clean, and that’s a precious commodity in this outlook.
Rusty.
