The Lowdown
Alright, let me take a look at what we’re working with for the next couple of weeks.
I’m not gonna sugarcoat it – this is a flat spell. For Octagon House (Octagon), the next 16 days are looking pretty bleak. There’s no real surf on the table. We’re looking at a long stretch of tiny, weak waves with nothing to get excited about. The first bit of any real size doesn’t show up until the very end of the period, and even then, it’s nothing special.
Starting from Sunday the 19th of July through the rest of the month, the swell is tiny. We’re talking about waves around 1 to 2 feet, with a short period of just 4 to 5 seconds. The combined energy is in the gutter – mostly single digits or low teens. That’s barely enough to ride a foamie. The wind is a mixed bag, but even on the cleaner mornings with a cross-off breeze, there’s just no swell to push things around. The water temperature is about 85°, which is a touch warmer than average for this time of year, so the water feels nice, but that’s about the only positive.
As we head into the first week of August, there’s a little bump. Monday the 3rd of August shows a morning with 3 feet of swell from the south, period around 5 seconds, and a clean cross-off wind. The energy is still weak (56), but it’s the best looking window in the whole outlook. Still, with that short period, it’s going to be pretty weak and crumbly – not the kind of waves that will have you excited.
If you just want to get wet and float around on a clean morning, the 3rd of August with that west-southwest cross-off breeze is your best chance. But for any real surfing, there’s nothing here that stands out. The energy never gets into the moderate range. This is one of those stretches where the ocean is just taking a nap.
Stay patient, keep an eye on the sky, and hopefully the next forecast brings some real swell.
