The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Sennen Cove over the next couple of weeks.
Right off the bat, I’ve got to be straight with you – the start of the period is a struggle. We’re looking at tiny, weak waves with a combined energy of just 33, and the wind is a fresh 19 mph from the NNE. It’s clean, but there’s nothing to ride. That’s Wednesday the 22nd.
The next few days aren’t much better. Thursday the 23rd shows a bit of a bump with a 3 ft swell from the north, but it’s short-period slop at 6 seconds and the energy reading is only 96. The wind is light, which is a positive, but the quality is still very ordinary. Friday and Saturday are a write-off – small and onshore, with a moderate breeze making a mess of things.
We do see a bit of a jump in size on Sunday the 26th, with a 8 ft swell from the WNW. The energy is strong at 637, but that’s paired with a 22 mph cross-onshore wind. It’s lumpy and difficult. That wave height is pushing into the territory where it’s only going to be for the experienced crew, and the wind is ruining it.
The highlight of the whole outlook, the only real standout, comes on the 4th of August. Tuesday morning we’ve got a 6 ft swell from the WSW, climbing to 6 ft in the afternoon. This is a proper groundswell with a 9-second period, and the real kicker is the wind: a clean, cross-off breeze from the SSE at 12-19 mph. The combined energy is strong at 618 for the morning and 533 in the afternoon. This is the window where it all comes together for a decent session. The water temp is 65°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.
Before that, on Monday the 3rd, the wind is howling from the south at 22 mph, making it cross-shore and lumpy. That’s a kite-surfing setup, not a paddling one. The week after that standout on the 4th sees the swell drop back down and the wind shift around, with nothing else worth getting excited about.
So, to sum it up: the first week and a half is a battle with small, weak, or blown-out conditions. The one true shot is Tuesday the 4th of August. It’s a long way off, so the forecast confidence is lower, but if it holds, that’s your day. Everything else is a pass.
Rusty.
