The Lowdown
Alright crew, Rusty here. Let’s break down what’s coming our way.
I won’t sugarcoat it – the start is a dud. Sunday the 19th and Monday the 20th are nothing to write home about, with small, weak swell and a crummy onshore wind. The water is sitting at about 59°F, which is a touch warmer than usual for this time of year (about 2°F warmer), so that’s a small bonus if you’re just having a paddle.
Things start to get interesting as we move through the week. The main event is *Steamer Lane-The Slot* (Santa Cruz). This is a well-known reef break that’s very consistent, so it’s always on the radar. The real window of opportunity is Friday the 24th. The afternoon session is the one: we’re looking at a 0.7m (2ft) groundswell from the SSW, but the period is a massive 24 seconds – that’s proper, deep-water energy. The combined energy reading is 786 (moderate), but the game-changer is the wind going glassy from the WNW. That’s going to put a perfect, clean face on the waves. With the swell direction matching the optimum west, the Slot should be threading nicely. Just remember, crowds are often an issue here, so be prepared to share the takeoff.
Saturday the 25th afternoon is another gem. The wind is glassy again, with a 0.8m (3ft) SSW swell at 21 seconds. The combined energy is 853 (moderate), and it’s going to be a clean, long-period groundswell. The Slot is the place to be for the weekend.
As we get into the second week, the swell sticks around but the conditions get a little messier. Monday the 27th morning sees a jump in size to 1.0m (3ft) SSW at 18 seconds, with a combined energy of 1795 (strong) – that’s a lot of punch. The wind is light cross-onshore, so it’s not pristine, but the power is there. Tuesday the 28th morning is glassy with a 1.1m (4ft) SSW swell at 18 seconds – another solid window for the experienced crew.
The next few days keep the wave heights between 1.0m and 1.4m (3ft to 5ft) with long-period energy, but the wind tends to be a little scratchy. The 30th of July afternoon sees a shift to a short-period WNW swell at 9 seconds, which is less appealing. The 31st of July afternoon offers a glassy, clean 0.7m (2ft) SSW swell for a fun, easy session.
The final weekend, August 1st and 2nd, brings a 1.2m to 1.3m (4ft to 4ft) S swell, but the wind is onshore, so it’ll be a bit lumpy. The 3rd of August drops off into a weak, short-period WNW swell with only a 9-second gap.
If you’re picking your sessions, make Friday the 24th afternoon and Saturday the 25th afternoon your top priority. That’s the cleanest, most lined-up swell of the whole run. The Slot is going to be a sight to see.
Rusty.
