Table - best surf conditions forecast for Trestles (Uppers) over the next 16 days.


Alright folks, Rusty here. Let’s have a proper look at what the next couple of weeks are serving up down at Trestles (Uppers). We’re looking at a typical summer run – plenty of small, cleanish windows but nothing that’s gonna have you ringing in sick to work. The water temp is sitting pretty average for the time of year, no weird anomalies to report.

Right, the first few days are a write-off, to be honest. Sunday the 12th through to Saturday the 19th, it’s a real struggle. We’ve got swell in the water – mostly around 1 ft to 3 ft, with a long-period groundswell from the SSW, but the wind is constantly messing it up. It’s cross-on or onshore nearly the whole time. The wave energy is weak to moderate (around 185-424), and the forecasts are all “poor surf conditions” or “marginal.” There’s a little spike on Saturday the 18th afternoon – a 6 ft S swell hits, and the energy jumps right up to 1585 – but the wind is a cross-on 9 mph from the WNW, so it’s gonna be a messy, choppy lump. Honestly, not worth paddling out for. That kind of setup, with the onshore wind and beach/reef mix, looks more interesting for a kite surfer than a traditional paddler.

Then we roll into the second week. Sunday the 19th is still poor. From Monday the 20th through Wednesday the 22nd, it’s a similar story: waist-to-chest high stuff (3 ft to 4 ft) but that consistent 9–12 mph cross-on wind from the W keeps the surface bumpy. The energy ticks up a bit, hitting 550 to 612, but the quality just isn’t there.

Now, here’s where it gets a little interesting. The real standout window is Saturday the 25th and Sunday the 26th. Saturday morning we see a 3 ft SSW groundswell with a period of 21 seconds, but the energy is strong at 1008, and the wind is light – 6 mph from the S, cross-on, but light enough to keep it semi-clean. Then Saturday afternoon gets better: the swell holds at 3 ft from the SSW, period still 21 seconds, and the wind swings light onshore from the SW at 6 mph. The energy jumps to 1115, and it’s the first proper sniff of a clean, workable day. That long period means the waves will have real push for the size, and the long gaps between sets will make paddling out a breeze.

Sunday the 26th morning is another one to circle. We’ve got a 3 ft SSW swell, a very long 20-second period, and the wind goes glassy-light from the SW at just 3 mph. The energy is strong at 1018. This is the pick of the fortnight. It’s not big, but that light offshore wind on a long-period groundswell at Trestles is a recipe for some clean, rippable walls. Could be a fun session before the onshore fills in later.

Monday the 27th morning holds a bit of promise too – 4 ft from the SSW, 18-second period, energy at 1233, and a light onshore breeze – but it’s a long way out, so keep your fingers crossed.

So, to wrap it up: the first week is a dud. The best on offer is looking like Saturday the 25th afternoon and especially Sunday the 26th morning. Get your board ready for that Sunday dawn patrol.

Rusty.
