The Lowdown
Alright, Rusty here, and I’ve got the lowdown on the only spot on the menu for the next couple of weeks: Haardebaaai.
First thing you need to know is that this place is a reef setup, and it’s not for the faint of heart. It’s an advanced wave, so if you’re still finding your feet, give this one a miss. The water temp is sitting at 60°F, which is pretty much what you’d expect for this time of year, nothing weird going on.
We’re looking at a bit of a slow start. The first few days of the forecast period are a write-off. Thursday the 6th and Friday the 7th are messy with onshore winds and poor conditions. You’ll be battling the elements more than riding a wave.
The first real glimmer of hope comes on Friday afternoon (7th August). The wind swings around to a light cross-offshore breeze, and the swell cleans right up. We’re looking at a solid 12ft groundswell from the SW, with a long period of 15 seconds. That’s proper energy, with a combined energy of 5020, but it’s a big swell for a reef. This is for the experienced lot only.
The standout session, the one you’d be a fool to miss, is Wednesday morning (12th August). It’s glassy. Dead flat calm, a light northerly breeze, and the swell is a clean 6ft from the SW with a very long period of 18 seconds. The combined energy is 2141, and the conditions are described as excellent for experienced surfers. This is a special window. The long period will make it a proper groundswell, so expect clean, powerful lines on the reef. It’s a rare moment of perfection.
After that, the run continues with some good options. Thursday morning (13th August) is looking clean with a 8ft SW swell, and Saturday morning (15th August) has a solid 7ft SW swell with a moderate offshore wind. The following Monday morning (17th August) sees another pulse of 10ft swell, but with strong offshore winds, it’ll be heavy. The second week is a bit more of a mixed bag, with some big winds and messy conditions creeping in from the 18th onwards, making it for the committed and the strong paddlers only.
So, to wrap it up: if you’re an advanced surfer, you’ve got a couple of absolute crackers in the first week. The glassy, long-period swell on the 12th is the one to circle on the calendar. After that, it gets a bit more hit-and-miss, but there’s always something to look at.
Rusty.
