The Lowdown

Alright folks, Rusty here. Let's have a proper look at what the next couple of weeks have in store for us down at Sennen Cove. It’s a bit of a mixed bag, got to be honest. For the first few days, the ocean’s going to be a bit of a messy beast, but there are a few windows of absolute magic if you're patient.

The week kicks off rough. Thursday the 3rd and Friday the 4th are write-offs. We've got a solid 6ft to 8ft of west-southwest swell, but it's getting chopped up by strong cross-onshore winds, 25 km/h. The energy reading is moderate, but it’s all over the shop, just lumpy and poor. Not worth getting wet for. You’d be fighting a losing battle. It stays onshore and messy right through to the 4th.

Then Saturday the 5th is where it all clicks into place. We wake up to a clean, glassy morning. The wind is dead calm, zero km/h, and that west-northwest swell is a proper 6ft. The period has jumped up to 12 seconds, so there's some proper push behind it. The energy is up there at 946, which is strong. This is the standout of the week, truly beautiful conditions. The afternoon stays okay, but the wind swings onshore and the swell backs off a touch, so get on it early.

Sunday the 6th sees the swell drop right away to under 3ft, and it’s small and clean but with not much power. The wind swings offshore, which is nice, but there's just nothing to ride.

Monday the 7th gets big again, over 8ft with a long 12 second period, but the wind is screaming onshore at 30 km/h, making it a total mess. The energy reading is huge, 1963, but it's all just lumpy and blown out. This one’s for the kite surfers, not us paddle surfers. That big, clean, contestable swell is just ruined by the wind.

The middle of the week from the 8th to the 11th is a story of poor conditions. Swell stays around 5ft to 8ft, but the wind is just never our friend. It chops everything up. There's a lot of moderate energy, but it's not working for us.

Saturday the 12th starts to look a bit more interesting. The swell drops to 6ft with a better 10 second period, and the wind swings light cross-shore. The models are calling it marginal, but with a little more luck, it could clean up.

After that, things go quiet for a few days until we get to Monday the 14th. That’s when a nice, clean 5ft west swell shows up with a light offshore breeze and clean conditions. It's a bit small, but it's clean. That’s our second standout.

Then Tuesday the 15th and Wednesday the 16th look pretty similar. We’re talking 4ft to 5ft of clean, glassy or cross-offshore waves. These mornings look like the pick of that second week. It's small, but it's clean and fun on the longboards.

After the 16th, it just fades out again, with the swell dropping and onshore winds returning. The water’s sitting at 63°F, which is about normal for the time of year, so a good 3/2 or maybe a 4/3 on the cooler days.

So, to sum it up. The real standout is Saturday morning, the 5th. Glassy, solid groundswell, perfect for Sennen. The other one to circle is Tuesday the 15th morning; it's smaller but still clean and glassy. The long-range stuff from the 14th to 16th is promising, but as always at that range, don't book the time off just yet.

Rusty out.

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.
