Table - best surf conditions forecast for Trestles (Uppers) over the next 16 days.
The Lowdown
Alright, let’s get into it. Right now, we’re looking at a pretty flat stretch for the next several days. The surf is small, the energy is weak, and there’s just nothing doing. The first few days of August are all showing poor conditions with tiny waves, light onshore breezes, and hardly any punch. The swell energy is low, between 120 and 354 (weak to moderate), but the wave heights are mostly around 1ft to 3ft - not enough to get excited about. It’s going to be a slow start.
We’ve got a gap here with no real recommendations until we get into the second week. The first hint of anything remotely surfable shows up on Friday the 14th, but it’s still marginal. The swell is small, around 2ft, with a period of 18 seconds from the SSW, and the energy bumps up to 443 (moderate). That’s a long period swell, which usually means better shape but can be tricky on a beach break. Wind is light cross-onshore, so not ideal, but it’s the best we’ve seen.
The real standout, and the only one worth pointing to, is Saturday the 15th into Sunday the 16th. We’ve got consistent 2ft to 3ft SSW swell with a period of 16 to 17 seconds, and combined energy around 341 to 392 (moderate). The wind is light and offshore in the mornings, which is a big plus for clean surf. This is Trestles (Uppers) - a reef and point break that handles a long period groundswell really well. The swell direction is SSW, which is close to the optimum from the west, so it should wrap in nicely. The water temperature is about average for this time of year, nothing unusual. Crowds are always a factor here, so expect plenty of company. For advanced surfers, the consistency is very good, and the shape should be there. It’s not big, but it’s clean and rideable.
So, if you’re patient, the best bet is the weekend of the 15th and 16th. The rest of the window is a write-off. Keep an eye on the forecasts, but for now, don’t rush.
