The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the local stretch.
The standout session this whole run is Saturday the 22nd, first thing. The morning is looking clean with a light offshore breeze, the swell is a friendly 3 ft from the SSE, and the energy is moderate (264). It’s the kind of start that’ll have you grinning. The water temperature is about average for this time of year, so nothing out of the ordinary there.
Saturday afternoon hangs in there, but the vibe drops off. Swell drops a touch to 3 ft, and while the wind is light, it’s just not as good as the morning. Sunday the 23rd is a write-off – small, messy, and cross-off winds. Monday the 24th morning offers a little clean 3 ft SSE swell with light offshore wind, but it’s nothing to write home about. Tuesday the 25th morning is decent, with 3 ft SSE swell and a gentle offshore – good energy (320), but not a standout.
Then things start to build. Wednesday the 26th morning has a clean 2 ft S swell with a very long 17-second period, pumping moderate energy (201). That long period means the waves will have shape, and the offshore wind keeps it tidy. Thursday the 27th morning is the main event of the first week – 5 ft of SSE swell, clean with a light offshore wind, and strong energy (805). That’s the one to circle. Friday the 28th morning is also a gem – glassy conditions, 3 ft SSE swell with a 16-second period, and strong energy (536). The waves will have push and be clean as a whistle.
There’s a lull from Saturday the 29th through Sunday the 30th, with only small, weak surf. Monday the 31st morning brings a bigger 7 ft SSW swell, but it’s short-period (8 seconds) and a bit much for beginners – that’s expert territory. Still, the energy is strong (837) and it’s clean. Tuesday the 1st of September morning is back to a clean 4 ft SSE swell with good energy (445).
The second week has some interesting moments. Wednesday the 2nd of September morning is clean with 3 ft SSE swell, but the afternoon packs a punch – 10 ft SSE swell, huge energy (2262), but it’s marginal for conditions. That’s big, long-period, and only for the brave. Thursday the 3rd of September morning is also big, with 8 ft SSE swell and very strong energy (2193), but the wind is cross-off, so it’s clean – expert only. Friday the 4th is a wipeout with strong cross-shore winds. Saturday the 5th of September afternoon has a 7 ft SSW swell with strong energy (1138), but it’s marginal. Sunday the 6th of September morning rounds things out nicely with 5 ft SSE swell, gentle offshore wind, and very good energy (599).
Best bet: Thursday the 27th morning or Friday the 28th morning for the cleanest, most fun waves. The big stuff at the end of the run is for the experienced crew only.
Rusty.
