The Lowdown
Alright folks, Rusty here. Let’s get straight into it for your local stretch.
We’re looking at a bit of a mixed bag over the next 16 days. The first few days bring some small, clean swell, but it’s a real slow burn. The standout period is definitely that window around the end of July into the start of August, when a bigger pulse of S swell pushes through. Up until then, it’s marginal.
The first real surfable day is Friday the 24th of July. The swell is tiny at 2ft from the SSW, but the period is a very long 24 seconds. That’s proper groundswell energy, but for a break like Trestles (Uppers), a reef and point setup, that long period can actually make it break a little too straight and fat. The water is a balmy 72°, which is much warmer than normal for this time of year – a solid 6° above average, so it’s a real treat if you’re getting in the water. The wind is a light SSW breeze, onshore, so it’s not glassy, but it’s not a washing machine either. The combined energy is moderate at 636, so there’s a bit of push, but it’s honestly a session for the patient longboarder. The scores are low, so don’t expect any fireworks.
Saturday the 25th and Sunday the 26th keep the same theme: small 3ft to 4ft SSW to SW swells, with periods dropping from 21 down to 18 seconds. The wind stays light onshore, with a cross-on component on Sunday morning that’ll put a bit of bump on the surface. The energy is moderate (916 to 876), but it’s still a waiting game.
Monday the 27th is where things start to look a bit more interesting. The swell bumps up to 4ft from the SSW, with a 19-second period and the combined energy hitting 1144 – solid moderate. Winds are light and onshore, which is a bit of a bummer, but it’s the best wave size we’ve seen. Still, the forecast is calling it marginal, so keep your expectations in check.
Best on offer: The real highlight is the end of July and the start of August. Friday the 31st of July and Saturday the 1st of August. This is when the swell really kicks. On Friday the 31st, we’re looking at 7ft to 7ft S swell with a 14-second period. That’s solid, pushy wave energy – the combined energy is a strong 1623 to 1929. This is advanced territory. If you’re not an expert, this will be too much. The wind is light cross-on, which will keep things a bit messy, but for the bigger, more powerful S swell, Trestles (Uppers) can handle it. Saturday the 1st of August drops slightly to 6ft, with a 13-second period, still a good size, and the wind is light onshore. The crowd situation at Trestles (Uppers) is always busy, so expect a full parking lot.
After that, the plug gets pulled. From Sunday the 2nd of August all the way through to Saturday the 8th of August, the swell absolutely tanks. We’re talking 1ft to 2ft, with weak energy below 200. The wind stays light cross-on or onshore, but with no swell, it’s a flat spell. A solid 6 to 7 day gap of nothing good. It’s a pretty normal dry spell for the area, so don’t be too bummed – forecasts can change, but right now, it’s looking like a time to take the board in for a repair.
Rusty.
