The Lowdown
Alright folks, Rusty here. Let’s have a look at what's coming down the line for Poldhu Cove. It’s a bit of a slow burn, but there is some magic on the horizon if you’re patient.
Right off the bat, the water temp is feeling pretty average for this time of year, nothing unusual to report. But the main story for the next week and a half is that we’ve got swell coming in, but the wind is just not playing ball. For the first ten days, from Friday the 11th right through to the 19th, it’s a write-off. The conditions are mostly choppy, wind-affected, or just plain messy. You get a bit of cross-shore here, a bit of onshore there, but nothing that’s going to clean up the faces. The energy is there for sure – we see some moderate readings like 430 on Friday morning, and even a solid 947 on Wednesday the 16th morning, but with a fresh cross-shore wind, it’s just lumpy chaos. Honestly, the set-up is so wind-swept for some of those days that it looks more interesting for a kite surfer than a paddle surfer. We’re talking a long stretch of poor-to-marginal conditions until the weekend after next.
Now, hold on to your board shorts, because the real promise kicks in on Sunday the 20th. That morning we get a proper pulse of long-period groundswell from the West – 2.2m (about 7ft) with a 14-second period and a combined energy of 1912. That’s a lot of power. The wind is a gentle cross-shore, so it’s a bit bumpy but the sets are going to be meaty. The afternoon cleans up even more with a cross-off breeze from the NNW, and the swell drops just a touch to 2.1m (about 7ft) but with a 13-second period. This is the first real taste of good surf.
But the standout window? That’s Monday the 21st and Tuesday the 22nd. Monday morning is a stunner: a clean 1.2m (about 4ft) swell from the West with a 12-second period, but the wind is offshore from the NE at 15 mph. That’s clean, lined-up, and the combined energy is a solid 739. This is genuinely good, clean surf. Monday afternoon stays clean as the wind drops right off to a light offshore from the ENE for some long, tidy lines on the 1.0m (about 3ft) swell. Tuesday afternoon is another beauty – a clean 1.0m (about 3ft) swell with a cross-off breeze, perfect for a longboard or a funboard.
Then we get to the big one. Friday the 25th is for the experienced crew only. The morning shows a solid 2.5m (about 8ft) swell from the WSW with a clean cross-off wind. The energy hits 1168 – that’s a lot of water moving. But the afternoon is where it gets serious: 3.0m (about 10ft) of swell from the WSW, a 10-second period, clean cross-off wind, and a combined energy of 3265. That is solid, powerful surf. This is not a beginner’s game; it’s for those who know what they’re doing and want a proper session. Saturday the 26th morning carries on that theme with another 3.0m (about 10ft) swell, but from the West this time, still clean and punchy. Over 8ft, you need your wits about you.
So to wrap it up: the first ten days are a right-off. Don’t bother. The real action starts on Sunday the 20th, and the absolute best bets for everyone are Monday the 21st for clean, friendly waves and Tuesday the 22nd afternoon for some glassy fun. For the big boys, Friday the 25th afternoon is the one to circle on the calendar. Keep an eye on that long-range forecast though – it’s promising but we’ve still got to get through that rough patch first.
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.

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.
