The Lowdown
Alright, cobber, Rusty here. Let’s have a look at what the next couple of weeks are serving up for Cobden Breakwater.
Right off the bat, the first couple of days are a bit of a nothing-show. We’ve got small, weak swell on Wednesday and Thursday, nothing that’s going to get you out of bed. The energy is weak (341, 249, 118) and the waves are just too small to be any real fun. You’re better off sorting your gear or checking the tide charts. It’s a flat spell to start, so we’re looking at a couple of days of patience before things start to move.
Then Friday morning things start to wake up. The swell fills in to a solid 5.6ft with a clean offshore breeze, and the energy jumps into the moderate range (587). That’s a proper sign of life. It’s a bit on the bigger side for the beginners, but for the everyday surfer, this is looking like a good one. The swell direction is from the NW, which is a bit off the optimum, but the clean conditions are going to make it work.
Friday afternoon is where it really turns on. The swell pushes up to 7.5ft and the energy is strong (1049). Offshore wind holds, and the note says it’s excellent for experienced surfers. This is a standout. The period is a touch short at 10 seconds, so it might not have that real groundswell push, but there’s plenty of power in it. This is the one to circle on the calendar.
Saturday keeps the fun going. The swell stays well overhead at 6.6ft to 6.9ft with a moderate offshore breeze. The period drops to 8 seconds, which is short-period windswell, so it’s going to be a bit more crumbly and softer. Still, it’s clean and there are waves to be had. The energy is strong (668, 838), so there’s plenty of push.
Now, Sunday morning is a big one, but not for the right reasons for most. The swell is forecast to be a massive 14.8ft, with the energy going through the roof (3838). That’s way oversize for this break. The comment says it’s too big, and they’re right. This is only for the most insane chargers, and even then, it’s likely to be a washing machine. The afternoon backs off to 7.2ft but the wind switches onshore, making it a messy, marginal session. That morning is experts-only, and honestly, I’d be watching from the shore.
Monday brings a welcome reset. The swell drops back to a clean 3.3ft, but the period jumps to 15 seconds. That’s a long-period groundswell, and it’s going to have some real push to it. The energy is moderate (656, 602). With light offshore and cross-off winds, it’s going to be glassy and clean. This is a quality day for the log or the fish. The long period might make it a bit straight at a beach break, but this is a breakwater, so it should be alright.
Tuesday is smaller again at 1.6ft, but that long period is still there (20 seconds!). It’s weak energy (370, 250), so it’s going to be fat and slow. A fun day for a longboard if you’re desperate, but not a day to get excited about.
Wednesday is a write-off. The wind is up and onshore, and the sea is going to be a mess. The morning is poor, and the afternoon brings a big 9.8ft of onshore slop. That’s a kite-surfing day, not a paddle-surfing day. The energy is strong (2810), but it’s all going to be blown out chop.
Thursday sees the wind swing back offshore, and the swell drops to a more manageable 6.2ft. The energy is strong (996). The morning is looking clean and very good. The period is a modest 11 seconds, but it should still have some shape. Another good option.
And then we get to the second week, and this is where things get real interesting.
Friday the 14th, a week and a half out, is a standout. Morning has clean 5.2ft swell from the W
