The Lowdown
Alright, let’s look at what’s cookin’ for Poldhu Cove. I’ll level with you, mate – the next couple of weeks are a bit of a rough patch, and there’s a gap before we see anything worth wettin’ a wetsuit.
First up, the water here is 64°F, which is a touch warmer than normal for this time of year. Nice.
The first week, from Monday the 31st of August right through to Thursday the 10th of September, is pretty much a washout. The wind is consistently onshore or cross-onshore, often blowin’ a solid breeze, and the wave comment is repeatedly “poor surf conditions”. The combined swell energy is moderate to strong – we’re talkin’ values like 1194 to 815 – so there’s power in the water, but it’s completely blown out and messy. There’s a stretch of mid-week where the swell gets up around 7 ft to 8 ft, but with cross-onshore winds and a cross-chop, it’s more of a kitesurfing setup than a clean paddle session. The period is mostly around 9 to 10 seconds, so it’s a decent groundswell, but it’s wasted.
There’s a noticeable gap of several days with no real hope. The only glimmer is a brief window on the morning of Saturday the 5th of September. We’ve got a light ESE cross-offshore breeze, clean conditions, and a 4 ft west swell runnin’ at 9 seconds. The combined energy is 277, which is moderate, and the score is a 2 out of 10 – the only non-zero score in the whole run. That Saturday mornin’ is your best bet by a long shot, and it’s still a modest one. The break is inconsistent, so don’t expect a set every minute, but if you’re keen, that’s the session.
After that, it drops right off. From the 6th of September onwards, the swell fades fast. By Saturday the 12th of September, we’re lookin’ at tiny 1.0 ft swell with a long 10-second period, but the energy is a weak 34. The wind goes offshore on the 13th, but the swell is barely a ripple at 0.7 ft – clean, but unsurfable. The long period groundswell that shows up on the 15th of September, with a 12-second period, is too small to do anything with and the wind is fresh.
So, the standout is clear: Saturday morning the 5th of September. It’s the only time in the whole 16-day window where the stars briefly line up. A clean 4 ft west swell with a light cross-off breeze. It’s not a big day, but it’s the only one worth your time. The break is inconsistent, so keep your expectations in check, but it’s the best on offer.

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.
