The Lowdown

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

Straight off the bat, I gotta be honest with ya – it’s a tough start. We’re looking at a real long stretch of messy, onshore junk before we finally get a window of clean surf. The first decent days are a long way off, so patience is the name of the game.

The first week and a half is pretty much a write-off. From Sunday the 30th of August right through to Friday the 11th of September, it’s a constant battle with cross-onshore winds and lumpy, choppy conditions. The swell is there, sure – we’ve got some solid pulses of energy, like on Monday the 31st of August with a 10 ft W swell and combined energy hitting 1744, and again on Friday the 4th of September with an 8 ft W swell at 1644 energy. But the wind is just ruining it. It’s fresh to strong cross-onshore the whole time, making for a real battle. That’s not surf for the faint-hearted or the beginners; that’s more of a kite-surfing session if you ask me. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year.

We do get a glimmer on Saturday the 5th of September, with a 5 ft WNW swell and a gentle cross-onshore breeze, but it’s only rated as marginal. Not worth getting too excited about.

Then we hit a real flat spell from Sunday the 6th of September through to Thursday the 10th of September. Swell drops right off, with heights down to 1 ft and combined energy as low as 33. The wind does go cross-offshore or even glassy at times, but there’s just nothing to work with. It’s clean but flat.

The real standout, the only one worth circling on the calendar, is Saturday the 12th of September. Finally, it all comes together. We’ve got a 4 ft W swell at 9 seconds, but the real winner is the wind. On Saturday morning, we get a light N breeze making it cross-offshore and clean. Then Saturday afternoon, it goes glassy – flat calm, with a light SW breeze. That’s the best you’re gonna get. The swell is small but clean, and the combined energy at 278 is modest but workable. For a long period of time, this is your best shot. The break is Sennen Cove, which is exposed and gets its optimum swell from the west, so that W swell is right on the money. It’s a beginner-friendly spot, very consistent, and crowds are only sometimes a problem. With the water feeling a touch warmer than normal, it’ll be a nice day out.

After that, the surf drops off again into the second week. Sunday the 13th and Monday the 14th of September are clean but tiny, with 2 ft and 1 ft swells respectively. Not enough push for a proper ride.

So, to sum it up: a long, poor run of wind-affected surf, then one shining window on Saturday the 12th of September. That’s your day. Get it while you can.

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.
