The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming our way for Cobden Breakwater over the next couple of weeks.
Right off the bat, Monday the 3rd is a write-off. We've got a solid 8ft swell on the way, but it's coming with a howling 19 mph onshore wind and rain. The wave energy is high (1594), but the conditions are pure slop. Not worth a second look.
The real action kicks off on Tuesday morning, the 4th. The wind swings around to an ESE cross-off at 9 mph, and the swell is still a beefy 8ft from the west, with a period of 10 seconds. The wave energy is pumping (1577). This is proper, powerful surf, but at that size, it's for the experienced crew only. The water temp is sitting at 54°, which is about average for this time of year. Tuesday afternoon drops a touch to 6ft, but still clean and very good.
Wednesday the 5th starts with a cleaner, smaller 3ft WSW swell (403) and light ESE winds. It's a nice, easy morning, but the period is a long 13 seconds, which at a breakwater can mean longer lulls between sets. The afternoon fades out with a tiny 3ft and a cross-on wind, so get it in the morning.
Thursday the 6th is tiny. The 2ft and 1ft swells are barely registering, so it's a day for the longboard if anything.
Now, Friday the 7th is a nice little pick-up. The morning is 5ft from the NW with a clean offshore breeze from the east. The afternoon gets even better, with a 7ft NW swell (979) and light offshore winds. That's a solid session.
Saturday the 8th and Sunday the 9th keep the trend going with clean, offshore winds and waist-to-chest high swell. It's consistent, fun surf.
The standout period, and the one to really circle on your calendar, is the window from Monday the 10th through to Wednesday the 12th. Monday morning, the 10th, sees a 4ft west swell with a 15-second period (763) and a light offshore – that's a beautiful, long-period groundswell with clean conditions. But the real beast is Wednesday the 12th. The morning bumps up to a massive 10ft west swell. The combined wave energy is an eye-watering 5578. The period is a very long 19 seconds, and the wind is light and cross-off. This is world-class, expert-only territory. This is not a place for the faint of heart. The afternoon stays at 10ft with a 17-second period (4708). This is the best on offer, no question.
The rest of the second week continues to deliver. Thursday the 13th gives us 5ft to 5ft west swell (1225) with clean cross-off winds. Friday the 14th is another big one, with 8ft to 7ft west swell and strong cross-off breezes.
The following Monday the 17th and Tuesday the 18th also look promising, with 7ft WNW swells and clean conditions, before fading into smaller, glassy waves on Tuesday afternoon.
So, to sum it up: the absolute best sessions are Wednesday the 12th and the surrounding days. The 10ft, 19-second west swell with light winds is a rare, powerful event. For the experienced surfers, that's the one. The whole run from the 7th to the 18th has a lot of quality, but that mid-week period is the standout.
Rusty.
