The Lowdown
Right then, let’s have a look at what’s coming up for Poldhu Cove. The water’s sitting at 66°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus if you’re getting in.
To be honest, the next week or so is pretty grim. The first recommendations don’t really kick in until Thursday the 27th of August, so there’s a big gap of quiet, small surf and poor conditions before that. From now until then, it’s mostly cross-onshore winds, small choppy waves, and nothing worth paddling out for. The waves are either too weak or too messy, with combined energy values sitting low, often under 150 (weak energy), so don’t hold your breath.
Things start to look interesting on the morning of Thursday the 27th of August. The winds go glassy – dead calm – and that’s a major positive. The swell is 6ft from the southwest, with a period of 7 seconds. It’s a bit short-period, so it’ll be a bit soft and lumpy, but the glassy conditions will make it rideable. The combined energy is moderate (363). This is the best chance for a paddle in the first week, but it’s not a standout.
The real standout comes on Friday the 28th of August. Now, this is a big one. The afternoon sees a 12ft swell from the southwest, with a period of 9 seconds. That’s a solid groundswell and the combined energy is a massive 2060 (very strong wave energy). The wind is light cross-onshore from the south-southwest, so it’s not perfect, but the size is serious. However, this is a big swell – over 8ft – so it’s for experts only. Expect it to be too big for most. Poldhu Cove is a fairly exposed beach, and with that size, it’s going to be a show for the brave. The morning of that day is also noteworthy, with 10ft swell and light cross-onshore winds, but still a big lump.
After that, the weekend of the 30th of August has a glassy morning on Sunday with 7ft swell from the west-southwest, but it’s short-period and the wind turns onshore by afternoon. The following Monday the 31st is a write-off with strong winds and messy conditions.
So, to sum it up: the best session on offer is the afternoon of Friday the 28th of August, but only if you’re an expert. For the average surfer, the glassy morning of Thursday the 27th of August is your best bet, though it’s nothing special. There’s a long gap of nothing until then, so don’t rush.

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. If you surf the same spot (Poldhu 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 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.
Poldhu Cove is 12 km (7 miles) from The Lizard. If you plan a holiday in South Cornwall, look for hotels and other accommodation in The Lizard. The Lizard has rooms for a wide range of budgets as well as car hire and transport links.
