The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Sennen Cove.
Honestly, it’s a tough run ahead. The models are showing a real lean spell for the next couple of weeks. There's no proper pulse of energy on the horizon, just a lot of small, choppy, and wind-affected days. The first real surfable day isn't even until Monday the 21st of July, and even then it’s nothing to write home about. We’re looking at a long stretch of poor conditions, with only a few fleeting moments of something rideable. The combined energy of the swells is weak, often staying below 100 (e.g., 40), and the water is a touch warmer than normal at 65°F.
We start on Monday morning, the 20th of July. The surf is tiny, only 1.0ft from the WNW. The wind is a light cross-off from the ENE, which keeps the surface clean, but there’s just no power. The swell period is a long 11 seconds, suggesting a bit of groundswell, but the height is too small for it to do anything. The afternoon goes cross and gets messy.
Tuesday the 21st sees a bump in size to 3ft, but it’s a short period windswell from the north at just 6 seconds. The wind is howling—12 mph in the morning, 16 mph in the afternoon—making it a cross-off and then cross-chop. It’s a mess.
The rest of that week and into the next is a write-off: small surf, unfavourable winds, and a lot of choppy, cross-onshore conditions. The swell tries to pick up a bit around Sunday the 26th of July, hitting 5ft from the WNW, but the wind is a fresh cross-onshore from the NNW at 19 mph. The combined energy jumps to 241-315, showing there’s some power, but the wind is just trashing the surface. This is more of a kite-surfing setup than a paddle-surfing one.
The only real glimmer in this 16-day window comes on Sunday morning, the 2nd of August. The swell is small, just 2ft from the west with a 9-second period, but the wind goes *glass*. That’s right, a glassy, clean morning. The combined energy is a weak 57, but for a longboard or a foamie, those tiny, clean lines will be the most fun you’ll have. It’s not a standout by any stretch, but it’s the best of a bad bunch.
For the rest of the run, the wind keeps up, the swell stays small, and the conditions are ordinary. You’ll be waiting a long time for a proper wave. Forecasts can change, but as it stands, that glassy Sunday morning on the 2nd of August is your only real window.
Rusty.

Information about the Sennen Cove Surf forecast
The above surf forecast table for Sennen Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sennen Cove can be found by selecting the local surf guide option on the grey menu. Our Sennen Cove surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Sennen Cove) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
