The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.

Right off the bat, we've got a bit of a flat spell to deal with. The first few days aren't looking good for a paddle, so we'll be waiting for things to settle down after a big, windy event. The first real window of opportunity opens up on Saturday, the 1st of August.

Saturday the 1st of August is where it starts to get interesting at Cobden Breakwater. The morning is looking clean with a 7ft swell rolling in from the west, and a cross-offshore breeze from the east-southeast at 9 mph. The combined energy is moderate (960), and with a period of 11 seconds, it's got some decent power behind it. This is likely your pick of the near-term, a solid, clean option for intermediate surfers. The afternoon drops off a bit, so make the most of the morning.

Sunday the 2nd of August is a bit of a mixed bag. The morning brings a smaller 3ft west swell with a clean cross-off breeze, but the period is short at 8 seconds, so it might be a bit weak. The real talking point for the afternoon is a glassy, 1ft swell from the west-southwest with a ridiculously long 21-second period. That's proper groundswell energy, but it's tiny. For a spot like a breakwater, that long period energy might just wrap in and offer some smooth, clean lines, even if it's small.

Monday the 3rd of August is a write-off. Strong onshore winds and rain means the 8ft swell is just going to be a mess. Best to give it a miss.

Tuesday the 4th of August is the standout of the first week. The morning is clean with a 4ft west-southwest groundswell (15-second period) and an offshore breeze. The combined energy is moderate (867). The afternoon is where it gets really good: a 5ft west swell, 14-second period, and light cross-offshore winds. The combined energy jumps to a strong 1078. This is excellent, clean, powerful surf for experienced surfers. This is the session to circle.

Wednesday the 5th and Thursday the 6th of August offer more clean, rideable waves, but the size drops off. Thursday morning has a 6ft north-west swell, but the period is short at 8 seconds, so it might be a bit lumpy. The wind is good though.

The following week, from Friday the 7th through to Wednesday the 13th of August, is mostly small. We're looking at waist-to-chest high stuff at best, with a lot of long-period, low-energy swells. The combined energy is mostly in the 100-300 range, which is weak. It's clean on most days, but the lack of swell makes it a gamble. The glassy afternoons are nice, but with 1ft to 3ft waves, it's more of a longboard or a cruise than a proper surf.

Now, there's a promising pulse showing up for the second week. Friday the 14th of August is the one to watch. The morning forecast shows a 7ft west swell with a 12-second period, clean cross-offshore winds, and a combined energy of 1611, which is strong. It's rated as excellent for experienced surfers. This is a long-range call, so it's promising but not a sure thing yet. Keep an eye on it.

Saturday the 15th of August looks like a good follow-up day, with a 3ft west swell, long 17-second period, and clean conditions. The energy is moderate (984).

Overall, the first week has a couple of solid windows, especially the 1st and the 4th. The second week is smaller overall, but that 14th of August is a real potential highlight if it holds. Water temperature doesn't look like it's straying too far from the norm for this time of year.

Rusty.
