The Lowdown
Righto, cobber, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
The overall story is that we start with a bit of a dud before it cleans up nicely. The first note on the board is for Friday the 31st of July, but that's a no-go. A big 16ft W swell is hitting Cobden Breakwater, but with a 22 mph onshore wind and a massive combined energy of 8005, it's just a washing machine. No good for a paddle. Give that one a miss.
The real action kicks off on Saturday the 1st of August. The morning brings a clean 6ft W swell with a 9 mph cross-offshore breeze from the ESE. The water temp is sitting at 54°, which is bang on average for the time of year, so no surprises there. The swell energy is a solid 852, showing it's got some push. The Saturday arvo is even better, with the wind dropping to a glassy 3 mph from the SW, and the swell dropping to 5ft from the W with a period of 10 seconds. That's proper clean, lined-up surf. This is the standout session of the whole outlook.
Sunday the 2nd still has some fun waves, but it's smaller. The morning has a 3ft WSW swell, clean with a cross-off breeze, and the afternoon goes glassy again with a tiny 1ft swell but a super-long 21-second period. That's a groundswell, and it'll be a bit fat and straight at this break, but it's still a beautiful thing to sit on.
Monday the 3rd gets messy. Onshore wind and a rising swell, with a 4ft WSW swell in the morning that builds to a lumpy 10ft in the arvo. Not worth it.
Tuesday the 4th of August is another cracker. The morning offers a 6ft W swell at 15 seconds, clean under a cross-offshore breeze, with a combined energy of 1411. That's excellent and will be perfect for experienced surfers. The wind is light, the waves have power, and it's a proper standout.
The rest of the first week sees a mix of smaller, cleaner swells and some cross-shore wind. Thursday the 6th has a 5ft NW swell in the morning, clean, and the afternoon goes glassy. Good, but not as good as the weekend.
The second week gets a bit more inconsistent. From the 8th of August onwards, the swell drops off significantly. There are some glassy mornings on the 9th with small 3ft WSW swells, but nothing with much punch. The standout in the second week is Monday the 10th of August afternoon. A 3ft WSW swell, but with a long 15-second period and a clean offshore breeze, the combined energy is 625. It’ll be clean and fun, but don't expect big barrels.
Later in the week, things get a bit weird. Thursday the 13th of August morning has a massive 12ft W swell, with a combined energy of 2774. The wind is cross-shore, but the forecast says it's too big for the break. That's one for the experts only, if anyone dares. Friday the 14th of August morning is a much better prospect, with a clean 6ft W swell at 14 seconds and a combined energy of 1227. That's a solid, clean option for experienced surfers.
So, the best on offer is Saturday the 1st of August afternoon with glassy conditions and a clean 5ft swell, and Tuesday the 4th of August morning with a powerful, clean 6ft swell. The rest is a mix of small clean days and some big, messy ones. The crowds at Cobden Breakwater are rare, so you'll have plenty of room.
Rusty.
