The Lowdown
Right, let’s have a look at what’s on the cards for the next couple of weeks. The only spot to really talk about is Poldhu Cove, and it’s a bit of a mixed bag. It’s a fairly exposed little cove, and it tends to pick up a solid SW groundswell, but it’s inconsistent. The water temp is about where you’d expect it to be for this time of year, so nothing weird there.
We kick off the forecast period with a bit of a dud, I’m afraid. The first few days are a write-off. Friday the 4th is a no-go with lumpy, cross-shore wind and rain, not worth a paddle. Saturday morning the 5th, though, is where it starts to get interesting. We get a nice 6ft swell from the west, with a proper 12-second period behind it. The real kicker is that glassy wind – just a whisper of air. That’s a huge positive, making for clean, organised lines. The combined energy is moderate (818), so it’s got a bit of push. This is the standout session of the whole outlook. Get on it.
Saturday afternoon and Sunday fade out fast, with the swell dropping and the wind turning onshore, so don’t get too excited.
Now, Monday the 7th morning sees a jump in size. We’re looking at 8ft of WSW swell, but the period is a shorter 13 seconds, and the wind is a moderate cross-shore. That’s a lot of water moving around (2003 combined energy), but it’s going to be a bit of a messy, choppy mess. It’s too big for beginners and will be a handful even for the experienced. The afternoon looks worse. The rest of that week is much the same story – plenty of swell, but always with a cross or onshore wind, keeping it lumpy and uninviting.
The following weekend, the 12th and 13th, the swell settles down to a more manageable 4ft, but with a lovely 10-11 second period and light, clean cross-off winds. The energy is light (340-346), but for a longboard or a funboard, it’ll be a million times better than the stuff we saw earlier. It’s a good, clean option.
The second week is a bit more of a waiting game. Monday the 14th has a weird 6ft swell with a very short 6-second period – that’s windswell, not proper surf. The 15th offers a better 6ft, 9-second swell with clean, light winds, so that’s a decent call. Looking further out, Wednesday the 16th morning is a real gem on paper: 5ft of west swell, glassy wind, and a clean 10-second period. That’s the other clear standout. After that, it’s mostly small, clean but weak waves right through to the 19th, with the swell dropping below 3ft.
So, to sum it up: the best on offer is that Saturday morning the 5th. It’s a clean, glassy, solid groundswell. The second best is the Wednesday morning the 16th – another glassy, clean session. The rest is either too windy, too messy, or too small. For a spot that’s inconsistent, it’s not a bad run, but you’ll need to pick your moments.

Information about the Poldhu Cove Surf forecast
The above surf forecast table for Poldhu Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Poldhu Cove can be found by selecting the local surf guide option on the grey menu. Our Poldhu 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.

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 Poldhu 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.
