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.
