The Lowdown

Alright, this is Rusty. Let’s be honest right out of the gate – the next couple of weeks around here are looking pretty flat and uninspiring. We’ve got a long stretch of small, weak, and messy conditions, so don’t get your hopes up for any proper sessions for a while. The first real window of anything rideable doesn’t show up until the second week, and even then it’s marginal.

We’re looking at Trestles (Lowers) as the only spot on the radar, and it’s a tough one to call. The water is running much warmer than normal for this time of year, sitting at 76°F with a 9°F anomaly, which is very unusual.

From Thursday afternoon, August 6th, right through to Monday, August 10th, the swell is tiny – around 2ft to 3ft – and the period is all over the place. The combined wave energy is moderate (203 to 449), but the wind is cross-on or onshore, making for choppy, poor surf. Honestly, it’s not worth paddling out. There’s a bit of a spike in energy on Tuesday afternoon, August 11th, with the combined energy hitting 428, but the swell is still only 2ft and the wave comment says “marginal.” Not exactly firing.

Wednesday, August 12th through to Sunday, August 16th, we see a slight bump in size, but it’s still small. The morning of Saturday, August 15th edges up to 4ft from the SSW with a 16-second period, and the combined energy is strong (724). But the wind is a gentle cross-onshore from the W at 9 mph, which will keep it bumpy. The wave comment for that afternoon is “poor surf conditions.” This is not a standout.

The best of a bad bunch looks like the morning of Sunday, August 16th. The swell is 3ft from the SSW with a 16-second period, and the combined energy is moderate (534). The wind is light and onshore from the SW at 6 mph, which is at least clean-ish. The wave comment is “marginal.” It’s the closest thing to a wave all week, but it’s nothing to write home about.

After that, from Monday, August 17th through to Friday, August 21st, the swell drops back to the 2ft to 3ft range, with light onshore to cross-onshore winds. The energy stays moderate (254 to 385), but the wave comments are consistently “poor” or “marginal.” There’s no real push.

Honestly, the whole 16-day window is a dud. The swell is too small, the wind is never properly offshore, and the wave quality is poor. If you’re desperate for a paddle, try the morning of August 16th at Trestles (Lowers), but don’t expect much. Otherwise, give it a miss.

Rusty.
