Alright folks, Rusty here. Let’s get into it for the Trestles stretch.

We’ve got a bit of a flat spell to start the week. The first real surf worth mentioning doesn’t kick off until Monday the 6th of July. It’s nothing crazy, but there’s some old, long-period groundswell pushing in from the SSW with wave heights around 3 ft and a beautiful 16-second period. That long period means the waves will have real shape and power for their size, especially at this reef and point set-up. The water temp is 68°, which is a touch warmer than normal for this time of year. The morning looks like the pick with light cross-on winds – not perfect glass, but the combined energy is moderate at 530, and it’s the cleanest the waves will be. It’s a marginal call though, so don’t expect perfection.

Tuesday the 7th bumps up slightly to 4 ft from the SSW, still with that delicious 18-second period. The swell energy climbs into the solid moderate range, hitting 853 in the morning. The wind is light and onshore from the SW in the morning – not ideal, but with waves that clean and long, it’s still worth a paddle. The afternoon sees a light cross-on breeze, but the energy is still pumping at 871. Crowds are always an issue here at Trestles (Uppers), so expect company.

Wednesday the 8th holds similar surf: 3 ft to 4 ft at 16 seconds, with light cross-on breezes. The energy is still healthy, although the quality drops a notch. Thursday is similar but the wind picks up a bit, and the energy starts to fade.

From Friday the 10th right through to late in the month, things turn really poor. We’re talking a solid week and a half of weak, choppy, or just flat conditions. Winds are mostly onshore or cross-onshore, and the swell drops off a cliff. The only potential glimmer comes right at the tail end of the forecast, on Sunday the 19th of July. The afternoon suddenly shows a bump of 6 ft from the S with a 13-second period and a jump in swell energy to 1534 – that’s strong energy. Winds are light and onshore, but it’s still a long way out, so treat it as promising but not locked in. If it holds, that’d be the best wave of the whole run for anyone who can handle a bit of size.

Overall, the first few days of next week are your best bet for a clean, longer-period swell, even if it’s not huge. After that, expect a long flat patch.

Rusty.

Information about the Trestles (Uppers) Surf forecast

The above surf forecast table for Trestles (Uppers) provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
