The Lowdown
Alright, Rusty here, giving you the lowdown on Tandjung-Lefts for the next couple of weeks. We’ve got a persistent SSW groundswell running, but the wind is going to be the main storyline for a while, with a cross-onshore flow keeping things choppy.
The first week is pretty average. You're looking at chest to head-high surf, around 6 to 8 feet, from the SSW. The ESE and SE winds are going to put a cross-on chop on the surface for most of this period. It’s surfable, but it’s going to be a bit of a battle. The pick of the early days might be Sunday morning, when the swell eases slightly to 7 feet, but it's still not great.
Things get more interesting starting Monday the 10th. The swell kicks up to 10 feet by Monday afternoon and holds through Tuesday, with a long 17-18 second period. That's proper groundswell, with strong energy readings. But again, the cross-on wind is still there, keeping it from being truly clean. It's big and powerful, but you'll be dealing with some chop.
Now, here's the standout. The 20th of August. That's a week out, so it's promising but not locked in. Early morning, the winds drop right out to a light 6 mph breeze, and we've got a solid 10 feet of SSW swell with an 18 second period. The energy is strong, and the surface is finally going to get a chance to clean up. This reef is going to look its best. This is the best window in the whole forecast, no doubt. The swell direction is perfect for the break, and with that light wind, it should be an excellent day for the advanced surfers. Crowds are a possibility, so get out there early.
Following that, the 21st and 22nd see the swell ease back to 8 feet and then 6 feet, and the wind picks back up to a cross-on 12 mph. The quality will drop off again.
So, to sum it up: sit tight through the first week of choppy conditions. There are rideable waves, but you'll be working for them. The one to circle on the calendar is Thursday the 20th – that's the day to make the call. It's going to be big, clean, and powerful. It might be too much for beginners – anything over 8 feet is expert territory – so if you're not confident, give it a miss. But for the rest of you, that's the one.
Rusty.
