The Lowdown
Alright, Rusty here again, talkin' in feet and all that.
We’ve got a mixed bag of conditions ahead, with a long wait for anything worth paddling out for. The first real nod to a surfable day is a solid couple of weeks off, so patience is the name of the game.
The water temperature is running at 69°, which is a touch warmer than normal for this time of year, so at least the wait won’t be a cold one.
We start off quiet. The first few days (13th through the 17th) are a write-off. The surf is tiny, with swell around 2ft to 2ft, and the wind is mostly cross-onshore, making things choppy and messy. Nothing to get excited about there.
The 18th and 19th show a glimmer of hope with slightly more energy, but the swell is still small (2ft to 4ft) and the conditions are still marginal. The combined energy readings are creeping up, hitting 419 and 788, but the wind is either onshore or light and cross, so the quality is just not there.
The 20th, 21st, and 22nd are more of the same: marginal surf, small swell, and light winds that aren’t quite clean enough. It’s a frustrating stretch.
Now, the standout. The 23rd of July, Thursday morning, is the day to circle. Things finally come together. Trestles (Uppers) is the spot. The swell jumps to 5ft from the south, with a period of 13 seconds, and the wind goes glassy. That’s the magic word. The combined energy hits 1382, a solid moderate push. It’s a reef and point setup, so that longer period south swell will wrap in nice and clean. This is for experienced surfers, as the size is up there, but the conditions are described as excellent. The afternoon on the same day sees the swell bump to 7ft, but the wind turns cross-onshore, making it less ideal. The morning is the call.
The 24th and 25th still have some decent size (5ft to 5ft), but the wind is cross-onshore, and the period drops off a bit. It’s still surfable, but not as clean as that Thursday morning.
The last few days of the forecast (26th to 28th) see the swell drop back down to 2ft to 3ft, with marginal conditions and light winds. The energy is still there (760 to 1127), but the size is lacking.
The best on offer is definitely Thursday the 23rd, morning session at Trestles (Uppers), with that glassy 5ft south swell. It’s the only real standout in the whole 16-day window.
Rusty.
