The Lowdown
Alright, Rusty here. Let's have a look at what the next couple of weeks are serving up. We're looking at a pretty extended run of small, tidy conditions, but nothing that's gonna blow your mind. The water temp is sitting at 70°F, which is a solid 7°F warmer than normal for this time of year – that's way above average, so ditch the wetsuit.
We're starting off this Sunday morning, the 16th of August, with small 2 ft swell from the SSW. The period is a long 16 seconds, so it's groundswell, and the combined energy is moderate at 222. The wind is a light cross-shore, so it's not totally clean, but it's not blown out either. That long period means the wave shape might be a bit fat and straight at a beach setup, but for a point break like Rincon - Rivermouth, it should wrap in nicely. The afternoon cleans up to a 2 ft swell with a cross-off breeze, making things look a bit cleaner.
Monday the 17th drops a touch to 2 ft from the SSW, still decent period at 15 seconds. Morning is a bit bumpy with cross-shore wind, but the afternoon cleans up again.
Tuesday the 18th is where we see a bit of a switch. The morning is still small at 2 ft, but Tuesday afternoon we get a pulse of 3 ft from the W, and the period drops to a short 8 seconds – that's windswell, less grunt. Still, with a clean cross-off breeze at 15 km/h, it'll be rideable but a bit weak.
The rest of the week into the weekend is a long stretch of tiny, knee-to-waist high waves. From Wednesday the 19th all the way through to Saturday the 22nd, we're mostly looking at 1 ft to 2 ft. The winds are light and mostly cross-off, so the surface will be smooth, but the energy is dropping. The combined energy numbers are mostly in the 100-200 range, peaking at 231 on Tuesday morning, but sliding down to 88 by Saturday morning. Not much push.
Sunday the 23rd stays small at 1 ft, but the period stretches back out to a very long 18 seconds from the SW. That’s a lot of time between sets, but those waves will have some real glide if they connect. Again, the light cross-off wind keeps it clean.
From Monday the 24th right through to Thursday the 27th, it's a proper flat spell. We're looking at 1.0 ft to 1 ft swells with combined energy figures dropping into the double digits – 45 on Monday afternoon, 62 on Wednesday afternoon. The conditions are clean, but there's just no water moving. This is a dead zone.
Things finally start to wake up again on Friday the 28th of August. The morning shows 1 ft from the SSW with a 16-second period, but that combined energy climbs back up to 193. The wind is light and cross-off. By Saturday the 29th, we have the best-looking window of the whole forecast. Saturday morning brings 2 ft from the SSW, 15-second period, and wind 15 km/h cross-off. The energy is at 224, and it’s labelled as "good surf conditions." This is your standout. The afternoon builds a little more to 2 ft from the SSW, but the wind picks up to 20 km/h – still cross-off, so it'll be choppier but rideable.
Sunday the 30th holds that 2 ft from the SSW period around 15 seconds, with a light cross-off breeze in the afternoon making it clean again. Energy stays solid around 210-216.
We finish off Monday the 31st of August with a drop back to 2 ft from the SSW, energy fading to 142 in the morning and down to 84 in the afternoon.
So, the real standout in this 16-day window is hands down Saturday the 29th of August, at Rincon - Rivermouth. You've got the biggest swell of the run at 2 ft to 2 ft from the SSW, a solid 15-second groundswell period, and a clean cross-off breeze. Combined energy is sitting at a moderate 224, and the wave comment calls it "good surf conditions." It's a point break, so that long period will wrap around nicely. Just a heads up, the crowds there can get busy often, so get in early. After the dry spell mid-week, this is the day to circle on your calendar.
Rusty, signing off.
