Table - best surf conditions forecast for Kennack Sands over the next 16 days.
Alright, let me tell ya, it's a pretty lean stretch ahead for us here at Kennack Sands. Honestly, lookin' at the whole 16-day window, the surf is gonna be a real struggle.
We start off with a big fat nothing. The first week is a write-off. From Wednesday the 8th to the end of the weekend on the 14th, the onshore wind is just relentless. The water is a touch warmer than normal at 64°F, but that's the only positive. The swell is tiny and onshore, with the combined energy barely reaching a whisper (just 2). It's all cross-onshore and choppy, or just plain blown out. Sunday the 12th sees the swell push up to 7ft, but with a 19-22 mph cross-onshore wind, it's a complete mess. By Monday the 13th, it's a full-on gale with 10ft swell and a near-gale wind - that's expert-only if you're completely mental, and honestly, it looks more like a session for the kite surfers than anyone with a paddle.
We finally get a break from the wind on Thursday the 16th of July. The wind swings offshore from the WNW, giving us a clean look at the waves. The swell is 5ft from the ESE with a period of 6-7 seconds. The combined energy is moderate (121-175). It's surfable, but very ordinary. Look, the waves are weak and a bit soft, but it's clean. The same goes for Friday the 17th morning - 4ft from the east with a light offshore. It's the best on offer, but that's not sayin' much. After that, it drops back down to tiny, unrideable surf for the rest of the outlook.
So, if you're desperate for a paddle, Thursday the 16th and Friday the 17th are your only real shots. The rest of the run is a solid blank. This is one of those times where the forecast can change, but right now, it's pretty grim.
