The Lowdown
Right then, let’s have a look at what’s on offer for Sennen Cove over the next couple of weeks.
Honestly, it’s a bit of a tough stretch for paddle surfing. The whole 16-day window is looking pretty average, with a long, quiet gap right at the start and only a few days that might offer something, but even those are a real compromise. The combined wave energy is weak for most of the first week, often under 100, and the wind is rarely on our side.
The first real chance, and it’s a long shot, comes on Monday the 10th of August. We’ve got a tiny 2ft swell from the WNW, with a period of 8 seconds. The wind is light and cross-off shore from the NE, which will keep the surface clean. It’s surfable, but very ordinary.
The next period to keep an eye on is around Wednesday the 12th of August. The swell picks up to 3ft from the WSW, and the combined energy jumps to a moderate 172. The wind is strong offshore from the ESE, which will make it clean, but with that strong breeze, paddling back out will be a mission. The wind is so strong it’s hard to get into the waves.
Later in the month, around Tuesday the 18th of August, the swell really kicks in, hitting 10ft from the WNW with a combined energy of 1241. That’s a lot of power, but the wind is cross-on shore from the NW, making it choppy and messy. This is expert-only territory, and even then, it’s a marginal call with questionable tide conditions. Honestly, for a beach break, this setup looks more interesting for kite surfing than paddle surfing.
The water temperature is about average for this time of year.
So, there’s no real standout here. The best bet for a clean, small wave session is probably Monday the 10th, if you’re desperate. For the more experienced, the big swell on the 18th is there, but it’s a battle against the wind. This is a tough forecast for Sennen Cove.
