Alright crew, Rusty here. Let’s talk about what’s cooking at Trestles (Lowers) over the next couple of weeks. To be honest, we’re in a bit of a flat spell right now.
The first half of the outlook is slim pickings. The first real chance to paddle out is on Monday the 7th of July. There’s a small 4ft SSW groundswell with a long 18 second period showing in the morning, with light onshore winds keeping it clean. The combined wave energy is moderate (836). The afternoon gets junkier as the wind picks up from the west.
Tuesday the 8th repeats the pattern: 4ft SSW swell (875 energy) with light winds in the morning, then it gets bumpy. Wednesday through Thursday is more of the same – ankle to knee high slop with cross-onshore breezes. Water temp is about 68°, a touch warmer than normal for July.
The Standout
Your real window comes on Saturday, July 18th. This one’s a long way off, so don’t book the day off yet, but there’s a pulse of longer-period SSW groundswell showing. Swell height is only about 3ft, but the period stretches to 18 seconds, and the energy jumps to (677) – that’s a proper moderate push. The wind will be from the SSE at a moderate breeze, so expect it to be cross-onshore and choppy.
That long period is great for power, but at a beach-and-reef break like Trestles, it might break a bit fast. Still, it’s the best we’ll see. The spot is very consistent and often packed, so paddle out ready for a crowd.
The Rest
From Sunday the 19th onwards, it fizzles back to knee-high dribble with small, short-period swell. Not much to write home about. This run is a waiting game.
Rusty, out.
