The Lowdown

Right, folks, Rusty here. Let’s have a look at the cards for this stretch of coast. I gotta be straight with you – the next couple of weeks are looking pretty flat and sad, but there’s one little window where things might just line up.

The first real chance to get wet comes in on Tuesday the 28th of July. The water is a balmy 73°, which is a good five degrees warmer than normal for this time of year, so you’ll be comfortable in a shorty or even just boardshorts. Tuesday morning sees Trestles (Uppers) picking up a 4ft SSW swell, but it’s coming from the wrong side of the compass for this spot. The wind is a cross-on 9 mph from the SSW, so it’s going to be choppy and a bit of a mess. The combined wave energy is still strong (1065), but the quality is not there. The afternoon cleans up with a lighter 6 mph onshore wind, but the swell drops slightly to 4ft.

Wednesday the 29th is more of the same – a 3ft to 4ft SSW swell, but the wind stays cross-on or onshore, keeping the surface bumpy. The wave energy is still moderate (567-722), but the condition is marginal. Thursday the 30th through Saturday the 1st of August has a bit more size, with 5ft to 5ft S swell, but the period drops to 13-14 seconds. The wind is light and onshore, so the surface might be a little less messy. Still, the scores are low.

Then Sunday the 2nd of August, the plug gets pulled. The swell drops to 2ft and the conditions become poor. This flat spell lasts for the next week and a half. From Sunday the 2nd through to Wednesday the 12th of August, we’re looking at tiny waves, mostly 1ft to 3ft, with poor conditions. The wind is light, but it’s either onshore or cross-on, so it’s not doing us any favors. The wave energy is weak (117-566). You’ll be hard-pressed to find a ride.

The one standout in this whole period is the very first day, Tuesday the 28th of July. Even though the wind is a bit of a factor, the 4ft SSW swell has a very long period of 17 seconds. That’s proper groundswell energy, and it’s hitting the reef and point setup at Trestles (Uppers) perfectly, as the optimum swell direction here is W. A long period swell like this will wrap around the point and set up some nice, long lines. The wave energy is strong (1065). The catch is that the wind is cross-on, which will put a slight chop on the face, but it’s still the best size and energy we’ll see. The afternoon cleans up with a lighter wind. It’s not perfect, but it’s the only session worth chasing.

Other than that, it’s flat and grim. This is a blank run that’s normal for the area in a quiet spell. Forecasts can change, but right now, you’re looking at one good day.

Rusty.
