The Lowdown
Alright folks, Rusty here. Let’s get into it for Sennen Cove. I’ve got to be straight with you – the next couple of weeks are looking pretty grim for a proper paddle. The whole period kicks off on Saturday the 25th of July, and straight away you’re fighting a moderate breeze from the NW, cross-on, making things choppy and messy. That small, weak swell isn’t doing anyone any favours. The water is a warm 66°, which is much warmer than normal for this time of year, so at least you won’t be shivering while you’re sitting there waiting for a clean one.
The first real hope shows up on Tuesday the 28th of July. We’ve got the wind swinging around to the ESE, giving us a clean cross-off breeze. The swell is small, only 3 ft, and the wave energy is weak (149), but it’s rideable and the conditions will be clean. Not a standout, but a chance to get wet.
Then, Wednesday the 29th of July morning is your best bet. The wind drops to absolutely glassy, calm, zero wind. The swell is tiny, 2 ft, with a moderate energy (87), but it’s clean as a whistle. For a beginner-friendly spot like Sennen Cove, which is very consistent and exposed to the west, this is the pick of the whole outlook. It’s not going to be pumping, but it will be the most enjoyable surf you’ll find in this run.
After that, it’s a long dry spell. From Wednesday afternoon right through to Tuesday the 4th of August, everything is either too onshore, too choppy, or just too small. There’s a brief pulse of energy on the 4th of August Tuesday morning, with a 5 ft swell from the SW and a clean cross-off wind, but the forecast says it’s marginal. The combined energy is moderate (514), but the period is short at 8 seconds, so it’ll be a bit weak and crumbly.
The rest of the window into August is just rough. Strong onshore winds from the W and NW, lumpy conditions, and tiny waves. Honestly, for the more experienced crew, the setup on Monday the 3rd of August afternoon has a 5 ft swell from the SW with moderate energy (371), but the fresh cross-shore wind makes it lumpy and messy. That’s more interesting for kite surfing than a good paddle.
So, bottom line: there’s no standout swell here. The only real chance to grab a clean, glassy wave is on the morning of Wednesday the 29th of July. After that, it’s a long wait for the next chance.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Sennen Cove may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
