The Lowdown
Alright, Rusty here. Let’s talk about what’s happening with the waves.
Look, I’m not gonna sugarcoat it. The next 16 days are a real mixed bag at Trestles (Lowers). We’ve got a bit of a tough start. The first few days from Tuesday, July 28th through to Thursday, July 30th are pretty lackluster, with waves only around 3ft to 4ft, and they’re coming from the SSW. The wind is a problem – it’s cross-onshore or onshore, keeping things choppy and messy. The water is a whopping 73°F with a 4°F anomaly, which is seriously unusual for this time of year, so you’ll feel that warm bath. The combined energy is moderate to strong, around 1062 to 834, but it’s not translating into quality surf thanks to the wind.
Friday, July 31st sees a little bump in size to 5ft, but the period drops to 13 seconds, and the wind is just light cross-onshore again. The energy is still in the moderate range (835 to 763), but it’s still not clean. Saturday, August 1st, the swell drops and the poor conditions continue. Things really go flat from Sunday, August 2nd through to Tuesday, August 12th as the swell drops to 1ft to 3ft, with combined energy tanking to as low as 116. The wind is light and cross-onshore or onshore for most of that stretch, so you’re looking at a long, flat run.
The only real glimmer of hope comes right at the tail end of the forecast. Wednesday, August 12th, the swell builds back to 3ft to 3ft from the SW, but the period jumps to 18 seconds – that’s proper groundswell. The energy picks up to 496 to 646, which is moderate. The wind is light and onshore, so it’s not perfect, but it’s the best thing on offer in this whole 16-day window. Given the long period, this will be best at a point or reef, but Trestles (Lowers) is a beach and reef setup, so it’ll still work, just watch for it to hit the reefs a bit more.
Honestly, if you’re looking for a standout, Wednesday, August 12th is your only real shot. Everything else is a write-off. It’s a long way out, so don’t get your hopes up too high, but it’s something to keep an eye on.
Rusty.
