The Lowdown
Howdy, Rusty here. Let’s be honest – Poldhu Cove is looking pretty flat and depressing for the next couple of weeks. It’s a spot that’s fairly open to a southwest swell and is alright for a beginner, but the surf just isn’t showing up. There’s a solid, quiet run of nearly twelve days with nothing worth writing home about, and only a couple of small windows that might get you wet.
Starting Friday the 14th and Saturday the 15th, we’ve got waist-high waves at 1.0m to 1.1m out of the west, but the wind is howling at 15 to 25 miles per hour from the west-northwest, blowing cross-shore or cross-onshore, leaving a choppy, messy surface. The combined energy is only around 152 to 166 – that’s weak. Sunday the 16th drops off hard to tiny 0.5m, with energy down to 33 to 39. Monday and Tuesday are just as poor, with no push and bad wind. It’s a tough stretch.
Wednesday the 19th shows a little pulse: 1.1m of west swell with a 10-second period bumping the combined energy to 262 to 279. But the wind is still cross-onshore from the WNW at 12 to 15 miles per hour, so the surface is choppy. Not worth the paddle. Thursday the 20th gets up to 1.3m to 1.5m of west-northwest swell, hitting 377 energy, but a fresh cross-shore wind at 18 miles per hour makes it lumpy. This looks more like a kite-surfing day than a clean surf session.
Friday the 21st and Saturday the 22nd finally turn clean. The wind switches to cross-offshore from the north and north-northwest at 15 to 18 miles per hour, giving us smooth conditions with 1.0m to 1.4m waves, but the period is only 7 seconds, so the waves are weak and short. The combined energy is 156 to 221. Not a standout.
From Sunday the 23rd through Tuesday the 25th, it’s back to tiny, weak waves: 0.4m to 0.2m, energy in the teens and twenties. A total bust.
The real bright moment comes on Wednesday the 26th in the morning. Glassy calm seas – a light southeast breeze at just 3 miles per hour – with a 0.5m west swell and a 10-second period. The combined energy is only 81, so it’s small, but the surface is dead flat and perfect for a clean, easy session. Then again on Friday the 28th in the morning: glassy, 0.8m west swell with an 8-second period, the wind is dead calm from the southwest at 3 miles per hour, and the energy is 89. For this area, those two mornings are the only true standouts – clean, small, and easy.
Friday the 28th afternoon goes downhill fast with a 25 mile per hour strong breeze and rain, and Saturday the 29th stays rough.
The water temperature is about average for late August around here. Nothing strange.
Bottom line: the first 12 days are a long, flat slog, with a couple of cleaner but weak days around the 21st and 22nd. The only real champions are the glassy mornings of Wednesday the 26th and Friday the 28th. Watch those windows.
Rusty.

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.
