The Lowdown
Alright, surfers, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty slow and mushy for our stretch of coast. We’ve got a window of decent swell but the wind is going to be a constant problem, keeping things lumpy and uninviting for the most part. It’s not a total loss, but you’re going to have to pick your moments and lower your expectations.
The first few days, starting Thursday the 3rd, are a write-off, to be honest. We’ve got a short-period south-southwest swell pushing in at around 2ft, but the cross-on breeze is just going to chop it all up. Not worth paddling out for.
Friday the 4th and Saturday the 5th see the swell fill in a touch, getting to 3ft to 4ft by Saturday afternoon. We’re still dealing with that cross-on wind. Saturday afternoon looks like the pick of this first stretch, with the wind clocking more onshore and the swell starting to show some shape. It’s still only marginal, but a few cleaner ones might roll through.
Now, here’s where it gets interesting, but frustrating. Sunday the 6th and Monday the 7th are our biggest swell of the run. We’re looking at 6ft of south-southwest groundswell. The problem? The wind is still on it. Sunday morning has that onshore wind making things lumpy, and by Monday afternoon it’s cross-on with more energy. This is proper-sized surf, over 5ft, so it’s not for the beginners. It’s got the power, but the surface conditions are going to be messy. Not the clean, lined-up Trestles we all dream about.
After that, it just fades out. Tuesday the 8th still has some size in the morning (6ft) but it drops off fast through the day. From Wednesday the 9th onwards, it’s a slow, sad slide into small, weak surf. We’re talking 1ft to 3ft waves with periods that drift around. There’s a glimmer of longer-period swell around the 14th and 17th, but the heights are tiny and the wind is all over the place. Those long-period swells at those sizes just won’t have the push.
So here’s the honest truth. There are no standout days in this 16-day window. The best you’re going to get is a marginal, sub-par session on Saturday the 5th or maybe Sunday the 6th if you’re desperate and don’t mind it rough. That bigger swell on Sunday is the only one with any real power, but it’s going to be hard work. We’ll take what we can get, but this isn't a week to be calling in sick for. Forecasts can shift, but as it stands, Trestles (Uppers) is going to be doing a whole lot of nothing. Keep an eye on it, but don't hold your breath.
Rusty, signing off.
