The Lowdown

Alright, let’s get straight into it.

The next couple of weeks are looking pretty average, to be honest. There’s a lot of onshore and cross-shore wind messing things up, and the surf quality is suffering for it. We’ve got a slow start, then a big pulse of energy that’s just going to be blown out, and then maybe a small window of cleaner conditions if we’re lucky. It’s all about picking the right moment.

First up, we don’t have anything worth paddling out for until Friday the 7th. The swell will be there, building to around 7ft from the west, but the wind is cross-shore and bumpy with a moderate breeze. The energy is moderate (1486), but an onshore wind state is killing it. The morning is your only shot, and even then it’s a bit of a gamble.

Saturday the 8th stays similar. The swell is up to 8ft from the west, with a bit more energy behind it (1877). It’s still cross-shore, but the wind is a touch lighter. The morning is again the pick of the day, but I’d call it marginal at best.

Here’s the big one. From the 10th through to the 15th, we’ve got some serious size coming in. We’re talking 12ft to 18ft of west-northwest groundswell. The energy numbers are massive, climbing from 3292 all the way up to 10837. But, and it’s a big but, the wind is just going to destroy it. Fresh to strong cross-shore and cross-onshore winds will have it all chopped up and messy. This is not a paddle-surfing situation. With that much swell and that much wind, this setup is looking a whole lot more interesting for the kite surfers than us. The water will be warm, around 85°, so you won't need a wetsuit, but you’ll be fighting a washing machine.

The standouts, such as they are, come right at the end of the forecast. The 17th and 18th of August are the ones to circle. The wind finally swings around to a cross-offshore direction, and the ocean starts to clean up. The swell is still solid, 12ft on the 17th morning and 10ft on the 18th, with moderate to strong energy (3074 and 2329). This is a much better setup for the reef, and the conditions will be far more favorable. The 18th afternoon looks great with a moderate breeze and clean conditions. It’s a long way out, so I wouldn’t book the time off just yet, but it’s the best chance we have for a proper session.

The last day, the 20th, has a small drop in swell to 5ft, but it’s coming from the west with a shorter period. The energy is weak (524), and the wind is light and cross-shore. It's still not ideal, but it’s the only clean-ish option in the last few days.

So, there you have it. A few bumpy, blown-out days, some serious size that’s unsurfable, and a couple of cleaner windows at the end. The 18th looks like the one to wait for.
