The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Alright, we're looking at a bit of a frustrating picture here. The good news is Trestles (Uppers) is a world-class reef and point break that handles a south swell beautifully, and it's very consistent. The bad news is the wind is just not playing ball for the first week. We've got a solid swell rolling in, but it's all coming with a cross-onshore or onshore wind, making things choppy and messy. The water temp is about average for this time of year, nothing unusual there.
The first few days, from July 28th through to the 1st of August, are a write-off. There's wave energy, with the combined energy hovering around 1000 (1067) during the first morning, but it's all "marginal surf forecast." Tuesday morning the 28th sees a 4ft swell from the SSW, but with a 9 mph cross-onshore wind, it's just going to be a bumpy, blown-out mess. The swell period is a very long 17 seconds, which is usually a good sign for a point like Trestles, but not with this wind. The rest of those days are more of the same, with the swell dropping and the wind staying onshore or cross-onshore.
Then, from the 2nd of August, the plug gets pulled. We hit a flat spell that lasts for a solid week. From Sunday the 2nd right through to the 12th of August, the forecast is nothing but "poor surf conditions" with tiny waves, mostly 1ft to 3ft. The combined energy drops to triple and even double digits, bottoming out at 95 (95) on the 6th. There's nothing to get excited about there.
The only faint glimmer is on the 12th of August, the last day of the forecast. The swell bumps up a tiny bit to 2ft from the SW with a period of 18 seconds, and the combined energy is 445 (445). But it's still a cross-onshore wind from the W at 9 mph, so it's going to be a choppy, weak day. Nothing for a board.
So, to be straight with you, there's no standout session in this 16-day window. The first week has the swell but the wind ruins it, and the second week has no swell. It's a bummer, but it happens. Don't give up on it though – Trestles is too good a wave to stay flat for long, and the forecasts can always change.
Rusty.
