The Lowdown
Alright, folks, Rusty here with a look at what we’ve got coming down the pike for Poldhu Cove. Gotta be straight with you – the next week and a half looks pretty average, but there’s one shining light a little further out that’s got my attention.
We’re starting off with a bit of a lull. The first couple of days are messy. Monday the 14th is a write-off – onshore wind and weak 4ft swell from the west with a short period, just poor. The water’s sitting at 64°, which feels a touch warmer than normal for this time of year, but you won’t be in it long. Tuesday gets a bit more size, 5 to 6ft, but the wind swings cross-shore and kicks up a lumpy chop. Still a no-go. Wednesday the 16th sees the swell jump to 7ft from the west with a much longer 11-second period, and we get a cross-offshore wind in the morning that keeps it clean. The combined energy is strong (1086), but it’s still considered marginal due to tide. That kind of long-period west swell could wrap in alright, but it’s one of those “watch and see” days for the experienced crew.
The rest of that first week and into the weekend stays pretty grim. Thursday and Friday have plenty of size – up to 7ft – but it’s all blown out by strong cross-shore and onshore winds. There’s a run of poor surf conditions that stretches right through to Sunday the 20th. We see some huge combined energy numbers on Friday (2579), but the wind is onshore and it’s just messy peaky waves, probably more interesting for the kite surfers than us paddle folk.
Now, for the one that stands out. Wait for Monday the 21st of September. That’s a beauty. The morning is clean with glassy conditions, a slight offshore from the ENE at just 3 mph. We get a 4ft west swell with a long 13-second period. It’s not massive, but the combined energy is solid at 549. This is the pick of the run – clean, lined-up waves due to the long period, and with that offshore wind, it’ll be worth the wait. Just bear in mind, Poldhu Cove can be inconsistent, so don’t expect a non-stop conveyor belt, but when the sets come through on that glassy morning, it’ll be special. Crowds are possible here.
After that, we get a few more clean days on the 22nd and 23rd with smaller 3 to 4ft swell and cross-offshore or glassy winds, but nothing that matches the quality of that Monday morning. By the 24th, the swell drops right off, and we finish the run with small, weak conditions and strong easterly cross-offshore winds that keep it clean but tiny. A couple of days near the end of the month show a slight bump in swell, but it’s still a gamble.
So to sum it up: grit your teeth through the first week of onshore junk, then circle Monday the 21st on your calendar. That’s the one to aim for.
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.
