The Lowdown
Hey folks, Rusty here. Let’s talk about what’s shaping up at Trestles (Uppers) over the next couple of weeks.
Honestly, it’s a pretty grim outlook for the next while. The water is sitting at 75°, which is a whopping 8° warmer than usual for this time of year – that’s very unusual, almost like bathwater. The swell energy is moderate at best, but the problem is that the wind is just never in the right place. For the first stretch from Sunday the 2nd right through to the end of the week, we’re looking at tiny waves around 1ft to 2ft, mostly from the SW. The wind is light, but it’s either onshore or cross-onshore, leaving the surface with small ripples or chop. The combined energy is weak to moderate (like 129 to 221), and the scores are all zero. It’s a flat spell, plain and simple.
We’ve got a long gap of about a week with nothing worth paddling out for. The first hint of any change starts around Sunday the 9th of August, but even then, it’s marginal. The swell finally bumps up a bit on Friday the 14th of August, with a 4ft SW swell and a 17-second period. That’s a long-period groundswell, which means better-shaped waves, but it’s also prone to breaking a bit too straight for a beach break – luckily, Trestles is a point and reef setup, so it should handle that well. The combined energy jumps to 755, which is strong, but the wind is a gentle cross-onshore breeze making it a bit choppy. It’s still only a marginal call.
The best on offer is really that Saturday the 15th of August. We’ve got a 4ft SW swell (16 seconds) and a 3ft SSW swell, giving us a moderate energy reading of 687. The wind is light and cross-onshore in the morning, but it’s still clean enough. This is as good as it gets, but for a spot like Trestles, that’s not saying much. It’s a consistent wave, but crowds are always a factor here, so expect company. The waves are waist to chest high, not too big for most, but the quality is just marginal due to the wind.
So, there’s really not a standout session in this window. The long-range for Sunday the 16th and Monday the 17th just fades back into the same old poor conditions. Hold tight, forecasts can change, but right now, it’s a waiting game.
Rusty.
