The Lowdown
G’day, Rusty here. Let’s be straight with you—this 16-day stretch is a rough one for Alexandra Headland. We’re looking at a whole lot of nothing, with a few flickers of hope that never really light up. The good news is the consistency is there, so it’s not a dead zone, but you’ll be scratching for a wave.
The opening run is poor. Tuesday the 18th has onshore cross-shores blowing into a junky 6 ft to 7 ft of short-period ESE swell (energy 340-444). That’s messy, the water’s a bit colder than normal for this time of year, and it’s not doing anyone any favors. Wednesday the 19th morning is only marginally better, with the swell dropping to 6 ft, but the cross-breeze keeps it lumpy. Thursday the 20th follows the same script—weak, cross-shore slop.
Then we hit a real flat spell. From Friday the 21st through the end of the month, the swell disappears. You’ll see waves around 3 ft to 4 ft, but they’re gutless, short-period, and mostly blown out by onshore winds. Friday morning the 21st has a glassy window with 4 ft of E swell (170 energy), but the period is only 7 seconds, so it’s soft and fat. Saturday the 22nd and Monday the 24th have similar glassy starts but the swell is even smaller and weaker—just not worth paddling out for.
There’s a tiny burst of energy on Thursday the 27th with a clean offshore wind, but the swell is only 2 ft. Forget it.
The second week stays bleak. The swell bottoms out to 1 ft to 2 ft from the 28th through the 1st of September, with mostly onshore or cross-onshore winds. The only glimmer is Wednesday the 2nd of September, when a 25 km/h SSE wind blows offshore and we get a clean 3 ft SE swell (117 energy). But the period is only 8 seconds, and it’s still tiny.
So, here’s the deal: there are no standout days. The best you can hope for is a quick dawn paddle on one of the glassy mornings mid-first week, but the waves are just too small and weak to get excited about. The consistency of the break means it won’t stay flat forever, but for this window, save your energy. It’s a blank run.
Rusty.
