The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for Trestles (Uppers) over the next couple of weeks.
Right off the bat, we’ve got a solid, long-period groundswell rolling in to start the week. Monday morning, July 27th, is looking like the pick of the entire forecast. We’re sitting on a clean 4ft swell from the SSW, with a very long 18-second period pushing a ton of energy into the water (1118). That’s proper groundswell. The wind is a light southwesterly, which is onshore, but it’s light enough that it’s not wrecking the shape. The water is sitting at 71°, which is much warmer than normal for this time of year, almost three degrees above average, so it’s a real treat. This is a break that’s very consistent, and with a northeast offshore being the ideal, a light onshore breeze isn’t the end of the world. This is the standout. The swell direction is a little off the optimum, but the sheer quality of the long-period energy makes it worth it. The access is easy, but crowds are always a factor here, so expect company.
The energy drops a touch into Monday afternoon, still decent, but the wind stays on. Tuesday the 28th sees a little more wind, a southerly at 9 mph creating a cross-on chop, making the 4ft swell a bit messier. It’s still surfable, but the quality takes a hit.
By Wednesday the 29th, the swell drops to 3ft and the period shortens up. The cross-onshore wind is light, but there’s a little wind ripple on the surface. It’s small and junky. Thursday the 30th sees a slight bump in size to 5ft, but the period is down to 14 seconds, and the wind is still onshore. The energy is still moderate (1052), but it’s not the same clean package as Monday.
Friday the 31st is similar, with a 5ft swell from the south, but the period is dropping to 13 seconds and the cross-onshore wind is back. It’s a bit of a mushburger. Saturday the 1st of August is a repeat of small, onshore, fading swell.
Then we hit a real lull. From Sunday the 2nd of August all the way through to Wednesday the 5th of August, the swell is tiny, only 1ft to 2ft, with the wind still cross-onshore or onshore. The energy is weak, in the 100-200 range. It’s a blank run. The conditions are poor and there’s just nothing to get excited about. The forecasts can change, but for now, it’s a dry spell.
The surf tries to creep back around Thursday the 6th of August, but it’s a weird one. The swell is only 1ft, but the period is a massive 21 seconds. That’s incredibly long, but there’s no size to push it. The energy is still low (291). It’s a tease.
Friday the 7th and Saturday the 8th of August show a slight increase to 2ft and 3ft, with periods dropping back to 17-18 seconds. The wind is light and onshore, so it’s clean but weak. The energy is still only moderate (around 500). It’s marginal.
The following week, from the 9th of August onward, the pattern is more of the same: small, weak swell, with the wind mostly onshore or cross-onshore. There’s a spike of very long-period energy (20 seconds) on the 10th of August, but again, the swell height is only 2ft so it’s just a bump on the surface. Nothing to make a plan for.
So, to wrap it up: Monday morning, July 27th, is your day. Get on it if you can. After that, the window closes up fast and the waiting game begins.
Rusty.
