The Lowdown
Alright, let’s get straight into it, folks. Rusty here, and I’ve got the lowdown on what’s coming our way.
Well, I’ll be honest with you – it’s a bit of a slow start. We’re looking at nearly a week of flat, messy conditions before anything worth paddling out for shows up. The first few days are a write-off for anyone wanting a proper surf. From Monday the 27th of July right through to Sunday the 2nd of August, it’s pretty much a bust. We’re talking tiny, weak swells, mostly cross-onshore winds, and the wave energy is barely registering – you’ll be lucky to get a ripple. The combined energy is pitiful, often in the single digits (5 to 30) and the swell is small, around 0.65ft to 2ft. It’s just not happening.
The first real glimmer of something better kicks off on Monday the 3rd of August. The wind finally swings offshore and cross-offshore, and while the swell is still small, the conditions get clean. On Tuesday the 4th of August afternoon, we start to see a bit of a pulse building, with the combined energy hitting 44 – still modest, but it’s a start.
Now, the standout period is from Wednesday the 5th of August through to Thursday the 6th of August. This is where it gets interesting. The wind turns offshore and stays there, blowing clean. The swell builds from 3ft up to 4ft, coming from the SW. The combined energy jumps up to a solid 132 on Wednesday afternoon, and then peaks at 165 on Thursday afternoon. That’s moderate energy, and for this spot, that’s the best we’ll see in the whole run. The wave period is around 7 seconds, so it’s a short-period swell, not the cleanest groundswell, but with that fresh offshore wind, it’ll be clean and punchy. This is the one to aim for. The water temperature is sitting at 67°F, which is much warmer than normal for this time of year – a full 5°F above average. That’s a nice bonus.
After that peak, it drops off quickly. Friday the 7th of August sees the swell fade right back down, and by Saturday the 8th of August, the wind swings onshore and gets strong, the swell gets lumpy, and the energy jumps up again, but it’s poor quality. That’s not for surfing, that’s a kite session. The rest of the second week is a mix of onshore rubbish and small, weak cross-shore waves, so don’t get your hopes up after that Thursday.
So, the call is clear. Whitsand Bay and Tregantle won’t give you much for the first week, but keep your eyes on Wednesday the 5th and Thursday the 6th of August. That’s the real window. The winds are offshore, the swell is the biggest of the run at 4ft from the SW, and the energy is solid. It’s not a classic long-period groundswell, but it’ll be the best we’ve got. The crowds can be a problem here sometimes, so get in early.
Rusty out.
