The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks. I’m going to be straight with you – it’s not a classic run. We’re looking at one main joint, Steamer Lane-The Slot (Santa Cruz), and it’s going to be a game of patience. Water temps are sitting about average for this time of year, so nothing weird going on there.

We kick off Thursday the 13th of August, and honestly, it’s a slow start. Swell is tiny, around 2ft from the SSW with a seriously long period of 16 seconds. That long period gives the wave some shape, but the combined energy is only 334 (weak), and we’ve got a light cross-onshore wind from the SSW at 6 mph. It’s not clean, and the conditions are poor. Friday the 14th is much the same – a little 2ft SSW swell, still that long period, and the wind is onshore from the SW at 6 mph. The energy picks up a touch to 396 (still weak), but it’s only a marginal call.

The weekend of the 15th and 16th sees the swell bump up to 3ft from the SSW, with those long 16-second intervals. The energy is climbing into the moderate range now (548 and 555). The mornings are your best chance with a light onshore breeze from the SW at 3-6 mph, but the afternoons get chopped up by cross-onshore wind. It’s still only a marginal forecast at best.

Monday the 17th is a write-off with 3ft waves and fading energy (487). Honestly, the first real glimmer of something different comes on Tuesday the 18th. The swell direction swings to the NW at 6ft, but the period drops right off to a short 8 seconds. That’s windswell, not groundswell, and it’s a bit jumbled. The energy is up to 849 (moderate). The wind is a light cross-onshore from the W at 6 mph. Still only marginal, but it’s the best we’ve seen so far.

Now, the standout in this whole outlook is Wednesday the 19th of August. The morning brings a solid 7ft of NW swell, still short period at 8 seconds, but the combined energy jumps right up to 1245 (strong). That’s a big number for this break. The wind is a light cross-onshore from the WSW at 6 mph. Now, 7ft with short period can be a bit unruly on a reef setup like the Lane, and it’s pushing into expert-only territory. But for the experienced crew, that’s the day to have a look if the tide lines up. It’s going to be powerful. Watch out though, Steamer Lane often has crowds, and with this being the only real pulse, you can expect it to be busy.

The rest of that week and into the next drops off again. Thursday the 20th is back to 4ft, energy down to 483, and poor conditions in the afternoon. The following days from the 21st to the 24th are all small – mostly between 1ft and 3ft – with weak to moderate energy. The wind stays light and mostly cross-onshore or onshore. It’s a lot of “marginal” or “poor” on the forecasts.

Looking further out to Tuesday the 26th, we get another bump. The morning brings 5ft from the NW, but it’s short period again at 8 seconds, energy at 546 (moderate). Wind is light onshore. The 27th pushes up to 5ft from the NW with energy of 823 (moderate). That’s a second-week hope, but at this range, treat it as a promising maybe. The 28th stays around 5ft.

So, the bottom line: don’t expect much until Tuesday the 18th. Wednesday the 19th is your true standout for size and power, but it’s for experts only and it’ll be crowded. After that, there’s a long gap of small slop until the 26th, which has a chance of being alright. It’s a patchy run, but the Lane can surprise you. Keep an eye on that Wednesday the 19th.

Rusty.
