The Lowdown
Hey, Rusty here. Let's break down the surf for the next couple of weeks.
This Saturday morning, July 18th, it's a slow start. A 3ft south swell with a 13-second period is there, but that cross-on wind from the SSW at 6 mph is making things a bit bumpy. The energy is moderate (388), so it's a marginal call. Not the best way to kick things off.
The real highlight is Monday, July 20th. We've got a solid 7ft to 8ft SSW swell, with a period of 13 to 14 seconds. The combined energy is strong to very strong (2015 and 1887). The best part? Glassy conditions all day, with no wind and clear skies in the morning. This is excellent surf for experienced surfers, so if you're a beginner, this is too big for you. Black Rocks Jetty is a very consistent reef break, exposed to the SW swell, which is the ideal direction. It can get crowded, so keep that in mind. The water temperature is about average for this time of year, so you'll be fine in a spring suit.
The following week, starting July 27th and 28th, we've got some very solid, very long-period SSW groundswell building. Monday morning the 27th is looking exceptional for expert surfers, with a 10ft swell, a 17-second period, and very strong energy (6043). The wind is a light cross-off from the NNE at 3 mph, keeping it clean. This is proper, powerful, long-period swell, and it will be handling well at the reef. Tuesday the 28th is also excellent, with a 10ft SSW swell and glassy conditions in the morning. These days are for experienced surfers only; over 8ft is expert territory.
Thursday the 30th of July is another standout, with an 12ft SSW swell, a 15-second period, and glassy conditions in the morning. The energy is very strong (5263), and it's exceptional for experts. This is a big, powerful swell.
So, the best on offer is Monday, July 20th for a very clean, solid day, and then the week starting July 27th for the real heavy stuff, but that is for the experienced crew only. The gaps in between are small, with some marginal days, but there are some great sessions to be had.
Rusty.
