Alright, Rusty here. Let’s have a look at what’s cookin’ at Trestles (Uppers).

Right off the bat, I gotta be straight with you – the next couple of weeks are lookin’ pretty flat and frustrating. The swell’s here, but it’s comin’ from the wrong direction, and the wind’s got a nasty cross-on feel to it that’s just wreckin’ the shape.

The first real chance of a wave that’s even worth paddlin’ out for doesn’t show up until Sunday the 5th of July. We’ve got a light breeze and a small 3ft SSW swell, but it’s an onshore wind and the condition is “marginal.” The combined swell energy is moderate at 505. The water temp is about average for the time of year. Still, it’s barely a blip on the radar, and Sunday afternoon is back to poor again. Then Monday the 6th of July gives us a similar story – 3ft from the SSW with light onshore winds and moderate energy (527). It’s frustrating, because you can feel the ocean wants to do something, but it just can’t get its act together.

Tuesday the 7th of July sees the swell tick up just a hair to 3ft from the SSW, with the energy climbing to a solid 801 – that’s moderate wave energy. The morning has light onshore wind, but it’s still in that “marginal” category. Wednesday the 8th of July is much the same, with 4ft SSW swell and the energy hitting 859. Still, the onshore wind and funky conditions are keepin’ it from being a standout.

Honestly, the only moment that deserves a mention is Wednesday the 15th of July. We’re down to a tiny 1ft swell from the SW, but the wind goes glassy in the afternoon. It’s a “Slight air” and the description says “glassy.” Combined energy is weak at 155, so it’s not gonna be a big wave session, but if you’re desperate for a clean little funboard wave in perfect conditions, that’s your window. It’s not a standout in size, but for cleanliness, it’s the best on offer across the whole forecast. But don’t expect any power.
Between the 5th and the 15th, there are a handful of other days with scores of 1 or 2 out of 10, but they’re all plagued by that cross-onshore wind and onshore wind. The swell direction is never the optimum W that this break loves.

So, to sum it up: the first week of July is a write-off for good surf. The second week is a whole lot of “poor” and “marginal” with only the 15th of July afternoon offering a short, glassy window on a very small swell. If you’re a beginner, none of this is too big for you, but the quality is just not there. For paddle surfing, it’s a tough stretch. For kite surfers? With that persistent cross-onshore wind at Trestles, the setup might be more interesting for them than it is for the rest of us.

Rusty.

A general guide to surfing at Trestles (Uppers) can be found by selecting the local surf guide option on the grey menu. Our Trestles (Uppers) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Trestles (Uppers) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
