The Lowdown
Righto, let’s have a look at what’s on offer for ADs/Doubles. The forecast period kicks off from Tuesday the 21st of July, but I’ll be honest with you, mate – the first week or so is a bit of a write-off. The wind is mostly cross or cross-on from the ENE, and the sea state is lumpy, choppy, or messy right through until the end of July. Combined wave energy is moderate to strong – values between 515 and 1907 – but the quality just isn’t there for a clean paddle. The water temp is sitting at 80°F, which is about average for this time of year, so no surprises there.
The first real glimmer of hope comes on Thursday the 30th of July. Thursday afternoon we’ve got some clouds, a light breeze from the NNE at 6 mph turning cross-offshore, and the report says clean. The swell is 7 ft from the ENE at 10 seconds, with combined energy of 882. That’s a moderate groundswell, and with that clean wind, it’s the standout of the whole forecast. This is the one to pencil in – the surf should be good, with a solid 7 ft of ENE groundswell and light offshore conditions. The break is fairly consistent, so waves should be rolling through. Keep in mind that at 7 ft, it’s getting solid for a lot of surfers – not a beginner wave, but a fun size for intermediates and above. Crowds are possible here, so get in early.
The period after that falls away again. From Friday the 31st of July right through to Wednesday the 5th of August, it’s back to poor conditions – cross-onshore winds, lumpy and messy, with swell heights mostly between 2 ft and 6 ft. The energy drops off to moderate to weak levels (342 to 732). There’s a bit of a long-period SSW swell showing on the 3rd and 5th of August, but with fresh cross-shore winds, it’s not going to be clean. The advice? Don’t bother. The Thursday the 30th is your window.
So, overall: a rough start, one clean afternoon on the 30th of July with 7 ft ENE groundswell and light offshore wind, then back to the doldrums. If you’re after a wave, aim for that Thursday afternoon.
