The Lowdown

Alright, Rusty here. Let’s break down what’s cookin’ for this stretch. It’s a slow burner, but there’s a couple of days that’ll make you smile.

The start of the week is flat. Tuesday the 25th is a dud – a tiny 0.4m SW swell with a 16-second period, but the combined energy is only 167, so it’s weak. The morning wind is a light cross from the SW at 6 mph, making for poor conditions. The water is 70°, which is a whopping 7° warmer than normal for this time of year – that’s really weird, like a warm bath. The afternoon cleans up with a cross-off breeze, but the swell is still too small. Wednesday the 26th is more of the same: 0.4m SW, clean but weak.

Thursday the 27th sees a slight bump to 0.7m from the WNW, but the period drops to a short 8 seconds, and the energy is only 69. The wind is cross-on, so it’s messy. Don’t bother. Friday the 28th is where we get a pulse. The morning brings a 0.5m SSW swell with a solid 19-second period – that’s long-period groundswell. The combined energy jumps to 289, so there’s some kick. The wind is light cross-off from the WSW at 6 mph, and the call is for good surf conditions. This is the standout of the first week. For a point break like Rincon - Rivermouth, that long period will make for nice, lined-up waves – just know it might get a bit straight, but here it’ll wrap in well. Crowds are listed as “often,” so expect some company.

Saturday the 29th and Sunday the 30th keep the SSW swell at 0.8m, with periods around 15 to 17 seconds and energy in the 300s. Winds are light and cross-off in the afternoons, giving clean surf. Saturday afternoon is good, but the mornings are marginal for tide. Monday the 31st fades back to weak, ordinary waves.

Now we hit a quiet stretch. From Tuesday the 1st of September through Thursday the 3rd, it’s mostly tiny – 0.2m to 0.5m – with very low energy. Friday the 4th of September brings a return. The afternoon has a 0.7m SSW swell with a 17-second period and energy of 321. The wind is a clean cross-off from the WSW at 9 mph. That’s another good session. Saturday the 5th of September has a similar 0.8m SSW swell with 16-second period and energy hitting 392, making it moderate to strong. The morning is marginal on tide, and the afternoon is clean but still marginal. Still, with that energy and clean wind, it’s a solid bet for those who can work the tide.

The second week is more of a whisper. Sunday the 6th and Monday the 7th see 0.6m to 0.7m SSW swells with periods around 14 to 15 seconds. Winds are light cross-off, keeping it clean. Energy stays in the 200s. After that, from Tuesday the 8th through Wednesday the 9th, it fades to 0.5m to 0.6m with lower energy, and the wind turns cross-on in the mornings, so it’s pretty ordinary.

The takeaway: The best days are Friday August 28th with that clean, long-period SSW groundswell and light cross-off breeze, followed by Friday September 4th afternoon for a similar setup. Everything else is small and average. Crowds will be a factor at Rincon, but the waves will be worth the company.

Rusty.
