The Lowdown
G’day, I’m Rusty. Let me break down the next stretch for you at Trestles (Uppers). This reef and point break is super consistent and open to west swell, so when it’s on, it’s a gem. Right now though, we’ve got a slow start before a little pulse late in July and into early August. The water temp is sitting at 22°, which is notably warmer than average – about three degrees above the norm, so that’s a nice treat for the early sessions.
We’re starting Friday the 24th of July with tiny surf. Swell is 0.7m from the southwest, a super long 24-second period, but it’s weak and the wind is a light cross-onshore, making it choppy. The combined energy is moderate (946), but honestly, it’s marginal. Saturday the 25th is the same story – 0.9m, long period, light onshore wind. Not much to get excited about. Sunday the 26th ticks up to 1.0m, period drops a little, and the wind stays light cross-onshore. Energy is moderate, but the quality’s off. Monday the 27th bumps to 1.3m from the SSW with 18-second period – still moderate energy (1144) and light onshore breezes. It’s there, but not clean. Tuesday the 28th holds around 1.3m with light cross-onshore wind, moderate energy (1070). Wednesday the 29th fades to 1.1m and the wind gets stronger, turning it choppy with weaker energy (682). Thursday the 30th is a total miss – 1.0m and cross-onshore wind, poor conditions.
Now, here’s the bright spot. Friday the 31st of July sees the swell jump to 1.8m from the south, period at 14 seconds, and the combined energy is strong at (1852). Wind is light onshore in the morning, then cross-onshore in the afternoon. It’s a decent pulse, but the direction isn’t the ideal west, and the wind isn’t clean. Still, for the confident crew, there’s size. Saturday the 1st of August holds at 1.8m from the SSW, with light onshore wind in the morning and a light breeze later. Energy is moderate to strong (1179), and conditions are better. This is the standout window – solid swell, light wind, and the break is consistent. Expect crowds though, because when it’s on, everyone knows.
Sunday the 2nd of August drops to 1.3m, and then it’s a long dry spell. From Monday the 3rd of August through Saturday the 8th of August, the surf is tiny – under 0.7m, short periods, weak energy (under 208), and persistent gentle cross-onshore wind. It’s poor conditions day after day, nearly a week with nothing worth paddling for. The break rarely works during this stretch.
Your best bet is Saturday the 1st of August. The morning offers 1.8m from the SSW with light wind and solid energy. It’s not glassy, but it’s the biggest and most consistent call in the whole outlook. Crowds are guaranteed, so get there early.
Rusty out.
