The Lowdown
Alright, I’m lookin’ at Sennen Cove here. Gotta be straight with you, this is a tough one to call a surf trip for. The wave energy is super low for the first week and a half, and even when a bit of swell shows up, the wind is a nightmare. The water’s sitting at 63°F, which is a touch warmer than usual for this time of year, so that’s a nice little bonus if you’re just paddling around.
The first real surf worth mentioning doesn’t show up until the 25th of July (Saturday morning). We’ve got a little pulse of swell from the west, about 2ft, with a period of 10 seconds, giving us a moderate 113 units of energy. But the wind is cross-onshore out of the NNW, so it’s going to be a bit choppy and messy. Not the cleanest, but it’s the first time we see any real push.
The 27th of July (Monday) sees a bit more size, with 3ft swell from the WNW, but again, the wind is cross-onshore from the NNW, making it a messy, lumpy affair. The energy is moderate at 104, but it’s not a pretty picture.
Things get a little more interesting toward the end of the month. The standout for the whole outlook is the 29th of July (Wednesday). The swell is from the west-northwest, 3ft in the morning and 4ft in the afternoon, with a period of 10 seconds. The combined energy jumps to 354 in the morning and 313 in the afternoon – that’s a solid, moderate-strong push of energy. But the wind is a moderate cross-shore from the south and south-southwest, so it’s not going to be glassy. It’s a bit of a lumpy, choppy mess, but there’s definitely some power to play with. This is the best the 16-day window has to offer, but it’s by no means perfect.
The 30th of July (Thursday) brings the biggest swell of the period, with 6ft from the west, but with a short period of 7 to 8 seconds. The energy is strong, hitting 319 and 328. But the wind is a moderate cross-onshore from the south-southwest and southwest, making it a choppy, bumpy mess. For a beach break like Sennen Cove, this setup is honestly more interesting for the kite surfers than us paddle surfers. The size is there, but the quality is poor.
For the rest of the days, it’s either tiny, blown out, or both. There’s a long, dry spell from the 15th up to the 25th, and then another gap between the 30th and the end of the outlook. It’s a rough run. If you’re desperate, the 29th is your best bet, but keep your expectations low. Things can change, but right now, it’s a “wait and see” kind of outlook.
