G’day, Rusty here. Well, I’ve got to be straight with you – this 16-day run for Trestles (Lowers) is a tough one to call. It’s a classic spot, a beach and reef setup that’s very consistent and exposed to the SW, and when it’s on, it’s world-class. But right now, we’re looking at a long stretch of poor to marginal conditions. The water’s sitting at 69°, which is a touch warmer than normal for this time of year.

The first real glimmer of anything rideable doesn’t pop up until Tuesday, July 7th. Things are pretty grim before that – July 3rd through the 6th is just a write-off, with small, weak swell and cross-onshore breezes ruining any chance of a clean wave. The combined energy is barely climbing past 650 on the 6th, which is only in the moderate range.

So, for Tuesday, July 7th, we finally get a bit of a pulse. The morning sees a 4 ft SSW swell, with a very long period of 18 seconds, and the wind goes light and offshore from the SSW. The wave energy is moderate, sitting at 822. That long 18-second period groundswell means the waves will have real shape and power, and the light offshore will keep ‘em clean. It’s still a marginal call – a 2 out of 10 in the guidance – because the swell size isn’t huge, and long period swells can sometimes be a bit tricky on a beach-break setup like this, mostly wanting to stand up and dump. Still, if you’re keen and you know the lineup, this is the pick of the whole forecast. The afternoon holds similar conditions with a light cross-onshore.

Wednesday, July 8th follows a similar pattern. The morning gives us a 4 ft SSW swell, 16-second period, and light offshore from the SW. The energy is moderate (873). It’s still just on the edge of being good, but Tuesday morning has the cleaner window.

After that, it’s back into the doldrums. From July 9th right through to July 18th, it’s a long, flat, and windy grind. The swell drops under 3 ft, periods shorten, and the wind stays mostly cross-onshore. The wave energy falls into the weak to moderate range, with many days below 300. The best you can hope for in that second week is a marginal session on July 18th (Saturday), with a 3 ft SW swell and a light cross-onshore, but the energy is still moderate. It’s a lot of paddling for not much reward.

To be honest, this is a period where you’d be better off finding something else to do. The setup is more interesting for kite surfing than paddle surfing if the wind picks up. For the rest of us, keep your eyes on Tuesday, July 7th – it’s the only real standout, and even then, it’s a marginal one.

Rusty.

Information about the Trestles (Lowers) Surf forecast

The above surf forecast table for Trestles (Lowers) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestles (Lowers) can be found by selecting the local surf guide option on the grey menu. Our Trestles (Lowers) 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. If you surf the same spot (Trestles (Lowers)) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 (Lowers) 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.
