The Lowdown

Alright folks, Rusty here. Let's get straight into it for this stretch of coast, focusing on the one spot we've got a good read on: Trestles (Uppers).

We're looking at a pretty drawn-out and, frankly, sub-par run of waves for the next 16 days. The overall pattern is one of persistent, weak, onshore-angled swell, with a lot of onshore or cross-onshore wind messing up the surface. The water is a wild 72° right now, which is a massive 6° warmer than usual for this time of year. It's like surfing in a bathtub, which is very unusual.

The first few days are a write-off. Monday the 20th through Thursday the 23rd are just a struggle. The swell is tiny, around 3ft to 3ft, and it's coming from the SSW or S with a short, weak period. The wind is mostly onshore from the SW, making it bumpy and unappealing. The combined wave energy is weak to moderate (around 541 to 893), and the scores are bottom of the barrel. Best to save your energy.

There's a bit of a glimmer on Friday the 24th. The wind finally goes light and onshore, with the swell holding at 4ft to 5ft from the SSW. The energy jumps up (1304), which is a sign of moderate, workable power. Saturday the 25th brings a super long period groundswell of 21 seconds from the SSW, but the height is tiny at 3ft. That long period will make it incredibly straight and walled-up at Uppers, which is a reef and point setup, so it might actually offer some decent, long walls if the tide is right. The morning wind is light onshore, but the afternoon gets a bit cross-onshore.

The best window actually looks like the stretch from the 25th of July right through to the 31st. The swell holds between 3ft and 4ft, all from the SSW or SW, with solid periods (15-19 seconds). The wave energy is consistently moderate to strong (806 to 1168). The winds are light, mostly cross-onshore, which will keep it from being perfect, but it'll be clean and rideable. The morning of Thursday the 30th has the best wind call of the whole run, with a light onshore breeze and the swell at 4ft. It's not pumping, but it's the most consistent, manageable surf we'll see.

Then it all fades out. The first week of August is a total bust. Swell drops to 1ft to 2ft, period is short, and the energy is pathetic (136 to 277). The wind is either onshore or cross-onshore, and the conditions are consistently 'poor'. It's a full-on, flat spell.

So, the standout here is the entire week from Friday the 24th of July through to Thursday the 30th of July. It's not a classic, but it's the most consistent, cleanest run of waves in a very long, drawn-out forecast. The best pick is likely Thursday the 30th morning, with the lightest wind and decent 4ft SSW swell. For a break that's very consistent, it's a surprisingly quiet period. It won't stay this poor for long, but right now, we're in a waiting game.

Rusty, signing off.
