The Lowdown
Alright, Rusty here. Let's talk about what we've got coming up for Cobden Breakwater.
The week starts off pretty promising with some good, clean waves on the menu. The water temperature is sitting at about 54°, which is pretty standard for this time of year.
Wednesday 29th July kicks things off with a solid 5ft swell from the W/SW, with a long 14-second period. That's a beautiful groundswell. The morning is looking choice with that offshore ENE breeze keeping things clean. The wave energy is moderate at 799, but it'll feel plenty punchy. The afternoon stays clean but the breeze swings to a cross-off, which is still fine.
Thursday 30th July morning is another good one, with a 4ft W swell, still a nice 13-second period, and clean conditions thanks to that offshore ENE wind. It's a great morning for an intermediate surfer. The afternoon, though, you need to watch out for. The wind goes cross-off from the north and cranks up to 19 mph, while the swell jumps to 8ft but with a short, weak 8-second period. It’s going to be a messy, lumpy 1174 of energy – more of a kite-surfing setup for the experienced ones.
Friday 31st July is a write-off. Onshore winds from the W/WNW, huge, sloppy swell, and just poor conditions all day.
Saturday 1st August morning is a clear winner. The swell drops to a clean 7ft from the west (11-second period) with light SE cross-off winds. The energy is moderate (1046), but the conditions are described as excellent for experienced surfers. This is a standout session. The afternoon goes marginal as a light cross-on wind creeps in.
Sunday 2nd August morning is a small but clean 3ft from the west with offshore cross-off winds. The afternoon gets glassy, with a tiny, tiny 1ft swell but a super long 21-second period. It'll be pretty slow and small.
Monday 3rd August morning is another gem. A 4ft WSW swell with a long 18-second period, clean and glassy off a light ESE breeze. The wave energy is solid at 1302. Excellent conditions for experienced surfers again. The afternoon gets glassy with a bigger 7ft W swell, but it’s a short 9-second period. Still, glassy is glassy.
Tuesday 4th August through to Thursday 7th August is a solid run of clean, surfable waves. Most mornings are clean with small to moderate west to WSW swells in the 2ft to 6ft range. The standout of this stretch is Friday morning 7th August, with a 6ft W swell (10-second period) and clean cross-off winds. That’s a good, fun day.
Saturday 8th and Sunday 9th August get smaller and a bit messier. Saturday has a tiny, long-period groundswell (1ft, 18 seconds), and Sunday afternoon turns into a choppy cross-on mess.
Now, hold onto your board for Monday 10th and Tuesday 11th August. Monday morning brings a clean 7ft W swell (13-second period, 1446 energy!). That’s excellent for experienced surfers. But Tuesday 11th August morning is the real standout of the whole 16 days. You’re looking at a solid 10ft W swell with a long 14-second period, all clean with an offshore ESE breeze. That’s a big, powerful, clean swell – 3508 of energy – and it’s for experts only. It’s a long way out, so keep an eye on it, but it’s the one to circle on the calendar.
Wednesday 13th August morning is another good one for experienced surfers with a 8ft NW swell and clean cross-off winds (2227 energy). The afternoon turns glassy with a clean 6ft WNW swell. A solid end to the forecast.
So, best on offer? The Saturday 1st August morning for a proper, clean session, and keep your fingers crossed for that big Tuesday 11th August morning. This break is fairly consistent, so the gaps in poor surf are short.
Rusty.
