The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the cards for Black Rocks Jetty over the next couple of weeks. We’re kicking off with a bit of a flat start, but once the swell kicks in, this spot has the potential for some absolute rippers, especially for the crew who aren’t afraid of a bit of size.
The water temp is sitting at 76°, which is a touch warmer than what we’d usually expect for this time of year. That’s a nice little bonus for a winter session.
Right now, things are pretty ordinary. Thursday the 23rd has a 5ft south swell coming in, but that wind is cross-onshore and the surfaces are choppy. Not worth paddling out for. We’ve got a bit of a wait until conditions clean up.
Friday the 24th morning is where the story starts to change. The swell drops to 3ft from the SSW with a 15-second period, and we get a clean cross-off breeze. That afternoon turns glassy with a 4ft SW groundswell. This is proper, clean surf for a longboard or a fish.
Saturday the 25th is all glass, with clean 4ft to 4ft SW/SSW swells. Consistent, clean, and no wind to mess it up. This is the kind of day you call in sick for if you can. Sunday morning the 26th holds that clean theme with 3ft from the SW, but longer period at 20 seconds – that’s a deep, powerful groundswell. Might get a little straight at this reef setup, but for the experienced lads, it’ll be a treat.
Now, Monday the 27th is the standout of the whole period. 8ft of SW groundswell with a 16-second period, and glassy conditions all day. The combined wave energy is massive (3297). This is not for beginners at all – it’s over 8ft and only for experts. But if you’ve got the skills, the waves will be excellent. Tuesday the 28th is nearly as good, with 8ft from the SSW, glassy, and even higher energy (3354). These two days are the real deal.
Wednesday the 29th stays good for the experienced crew with 6ft SSW and glassy conditions, and that quality holds into the weekend. Friday the 31st morning sees another solid 7ft from the SSW with glass, but the afternoon gets a bit messy with a risk of thunderstorms and onshore wind. Still, that morning session will be firing.
Heading into the first week of August, we’ve got some nice, more manageable waves. Saturday the 1st gives us 6ft in the morning and 6ft in the afternoon – glassy both sessions. Good for intermediate to advanced surfers. Sunday the 2nd is smaller at 3ft, but still clean.
After that, the surf slowly winds down through the week. By Wednesday the 5th and Thursday the 6th, we’re down to knee-high dribble with weak energy (69 to 120). The last few days of the outlook are flat, with no real surf to speak of. A solid blank run to finish things off.
So, the call is this: the Monday 27th and Tuesday 28th of July are the absolute standouts. Big, powerful, glassy SSW groundswell for experts only. The weekends of the 25th-26th and the 1st-2nd of August are great for the rest of us.
Rusty out.
