Sennen Cove Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Sennen Cove over the next couple of weeks.

Honestly, for the first week or so, it’s a bit of a tough one. The forecast is calling for a lot of poor surf conditions right through the end of July and into early August. We’ve got a mix of onshore and cross-onshore winds, and the swell energy is mostly weak, with the combined energy sitting in the double digits and low hundreds (96 to 152). The waves are just too small and messy to get excited about. There’s a stretch of several days here where it’s really not worth paddling out.

The first real glimmer of hope comes around Monday, the 3rd of August. The morning sees a clean, light offshore breeze from the SSE, with a small but surfable 5 ft swell from the N. The period is a short 6 seconds, so it won’t be the most powerful, but with clean conditions and the wave energy at a moderate 162, it’s a chance to get wet. The afternoon stays clean with an offshore breeze at 6 mph, and the swell holds at 4 ft. It’s not a classic, but it’s the best we’ve got in the first week.

Now, the standout window is further out. Sunday, the 9th of August, sees a big pulse of energy arrive. The morning brings a 7 ft swell from the WSW, but it’s blown out by a strong 19 mph onshore wind, so that’s a write-off. However, the afternoon of the 9th and into Monday the 10th is where it gets interesting. Sunday afternoon sees a jump to a 8 ft swell from the WSW with a period of 11 seconds, giving us a very strong 1504 combined energy. The wind is still onshore, so it’s messy, but the power is there.

The real highlight is Monday morning, the 10th of August. We’re looking at a solid 10 ft groundswell from the WSW, with a period of 10 seconds. The combined energy is a massive 1690, which is a lot of water moving. The wind is cross-onshore from the NNW at 19 mph, which won’t give you glassy perfection, but for a spot as exposed as Sennen Cove, this is some serious, powerful swell. This is definitely one for experienced surfers only, as those 10 ft waves are too big for beginners. The water temperature is sitting at 67°F, which is 5°F warmer than normal for this time of year, so you’ll be in for a pleasant surprise.

The following Tuesday, the 11th of August, still has some push with a 6 ft swell from the W, but the wind is onshore again, making it a marginal call. The rest of the run looks like it fades back into small, poor conditions.

So, to sum it up: the first week is a wipeout. The best bet on offer is the big swell event on Monday, the 10th of August. It’s a powerful, expert-only session with clean-ish cross-offshore winds. If you’re a capable surfer, that’s your window. The water is also notably warmer than average, which is a nice bonus.

Rusty.
