The Lowdown
Alright, let's take a look at what's cookin' for Kennack Sands. I gotta be honest, it's a rough stretch ahead. Don't go chasin' any big dreams here for a while.
The first bit of action we see is on Tuesday, July 14th, but it's a total mess. We got a fresh cross-onshore wind with a lumpy 6ft swell from the east, and the energy's weak (337). The water temp is about average for the time of year, but that's the only decent thing. The whole week is pretty much a bust. On Thursday afternoon, the wind goes light and clean, but the swell drops out, so there's nothin' to ride.
We then hit a proper dead zone from Friday, July 17th through to Monday, July 20th. There's simply no swell to speak of, just clean, flat water. It's the kind of gap that makes you wonder if the ocean's on vacation.
Come Tuesday, July 22nd, we finally see a pulse. Wednesday morning that week shows a 8ft swell from the east-southeast, with a period of 7 seconds. The energy is moderate (466), and the wind is a clean cross-offshore. That's the standout of the whole forecast, but it's a big one. At 8ft, this is for experienced surfers only. It's a short-period swell, so it won't have the punch of a groundswell, but it's the only window with any real size and clean conditions. The break is rated as inconsistent and sheltered, so don't expect it to be pumpin' all day, but on Wednesday morning it's the only game in town.
The rest of the week after that drops off quick, and by Friday, July 24th, it's back to flat or tiny, weak swells with no energy. The very end of the month sees a bit of a south swell, but it's tiny, with a long period that'll be too weak to do anything meaningful at this beach. All in all, a tough outlook.
