The Lowdown
Right, folks, Rusty here. Let's have a look at what Poldhu Cove is offering over the next couple of weeks. It’s a fairly exposed spot that likes a good SW swell, but this forecast is a bit of a test of patience.
We start with a blank run, to be honest. For the first week, from Saturday August 15 right through to Wednesday August 19, the surf is small, messy, and onshore. The winds are cross to cross-on from the north and west, and the swell is tiny, coming in at under 3ft. The combined wave energy is weak, mostly sitting between 32-104 on the meter. It’s proper "poor surf conditions" all the way. The water temp is 67°, which is a notable 4° warmer than normal for this time of year – a nice little bonus if you do go for a paddle, but the waves just aren’t there.
Thursday August 20 sees a bit of a push, with swell height rising to 6ft from the west, but the energy ramps up to 575-613, which is moderate. The problem is the cross-onshore wind from the WNW at 19 mph. It’s lumpy and choppy. This is not a day for a longboard. Given the poor quality and the wind, this setup is more interesting for kite surfing than paddle surfing.
Friday August 21 cleans up a little – cross-off winds from the NNW at 16-19 mph get the surface glassy, and the swell drops to 5ft from the west with a moderate energy reading of 462. It’s cleaner, but still not anything to write home about. The waves are there, but they aren't going to be anything special.
Then we hit a proper lull. From Saturday August 22 all the way through to the end of the month, the swell drops right off. For over a week, the swell height is mostly under 2ft, with energy readings well below 100 – often as low as 15-22. It’s looking flat. There is a brief moment on the afternoon of Saturday August 22 with glassy conditions and a tiny 2ft west swell, but it’s barely a ripple. Sunday August 23 sees a period jump to 11 seconds with a 1ft WSW groundswell, but it's still tiny, and the wind is a strong 25 mph from the east.
Even the last few days of the month, like Friday August 28 and Saturday August 29, see a tiny 2-2ft west swell with clean cross-off winds. The combined energy is still weak (30-69). It’s tiny, clean, and frustrating. Honestly, the best wave of the whole period might be that late Saturday afternoon on August 22 when it’s glassy, but there’s no real push.
So, to sum it up: don't get your hopes up. The first week is a write-off with onshore junk. There’s a brief, cleaner period on Friday August 21 with head-high-ish swell (5ft from the west) but it’s not good quality. After that, it’s a long, flat spell for more than a week. Hold tight, check back in a few days.

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.
