The Lowdown
Alright, let’s get into it. It’s looking pretty quiet out there for the next two weeks. The water is sitting at about 52°, which is over 6° colder than normal for July – that’s a major anomaly, so you’ll want a thick wetsuit.
We start off with a rough patch. From Thursday the 16th all the way through Sunday the 19th, it’s mostly small and messy. Swell heights are around 2ft to 3ft, short period, and the wind is onshore or cross-onshore. The combined energy readings are all below 70 (weak). There’s a glassy morning on Sunday the 19th, but no swell at all – zero energy. So that’s a solid four-day stretch with nothing worth chasing.
Monday the 20th finally offers a little something. The morning brings a 3ft swell from the west, with an 8-second period. The combined energy hits 144 (moderate). The wind is a light cross-offshore from the east at around 6 mph, keeping things clean. It’s surfable, but only just. Tuesday the 21st is similar but a touch smaller at 3ft from the WNW, and the afternoon goes glassy – that might be your best window. Still, nothing to get excited about.
After that, it’s back downhill. From Wednesday the 22nd onward, the swell fades fast. We’re down to 2ft and smaller, with poor wind, and by the weekend of the 26th and 27th, there’s barely a bump. The combined energy numbers are tiny – single digits and low teens. That’s another several-day gap with no surf.
The long-range into the end of the month shows nothing. Zero. It’s a dry spell, and for this spot, that’s pretty normal. Forecasts can change, but right now, I’d say leave the stick at home and wait for a better run.
