The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Alright, I gotta be straight with you: the surf forecast for Trestles (Uppers) is pretty grim for the next week. The energy just isn't there. We’ve got a run of poor conditions starting Friday the 31st of July, with a small, short-period S swell pushing in around 4ft, but the southerly wind is on it, making it a messy, marginal affair. The combined swell energy is moderate at best (701) but the wave comment says it all. It’s not worth paddling out for.
This poor run stretches all the way through to the first week of August. From Saturday the 1st right through to Sunday the 9th, we’re looking at tiny, weak swells from the SW and SSW, mostly under 3ft. The wind is light and onshore, which is about the only positive, but the waves are just too small and gutless to get excited about. The combined energy drops into the low hundreds (137 to 440), which is weak. Honestly, it’s a kite-surfing kind of setup if anything, with clean, tiny lines.
Now, there’s a little glimmer of hope for Saturday the 15th of August. The morning shows a bit more life with a 3ft SSW swell and a 16-second period. That’s a proper groundswell, and the light offshore wind from the SW would groom it nicely. The combined energy (575) is moderate, but it’s the best we’ve got in the whole window. This is the standout, but it’s a long way off, so keep an eye on it. The afternoon looks like it will get a bit cross-onshore, so the morning session is the one to target.
For the rest of the second week, from the 10th to the 14th, it’s more of the same. Small, sub-3ft swells, mostly from the SW and SSW. The periods are decent (14-18 seconds) but the energy is just too low to push anything worthwhile into the break. The water’s sitting at a very warm 75°F, which is over 7°F warmer than normal for this time of year. That’s unusual, but it doesn’t help the waves.
So, bottom line: if you’re desperate, the morning of Saturday the 15th of August is the only real chance for a clean, rideable wave. Otherwise, it’s a long, flat stretch. Hang tight, forecasts can change.
Rusty.
