The Lowdown
Right then, let’s have a look at what’s on the cards for Poldhu Cove. It’s a bit of a slow start, to be honest. The first few days are a write-off, with messy cross-shore winds and lumpy conditions that are more trouble than they’re worth. We’re looking at a gap right through Tuesday afternoon the 8th and all through Wednesday and Thursday the 9th and 10th, with nothing but poor surf. The water temp is a touch warmer than normal for this time of year, sitting at 64°F.
Friday morning the 11th is where we finally get a glimpse of something decent. The wind swings to a light NNW cross-offshore breeze, and that cleans things up nicely. You’ve got a 5ft swell rolling in from the WSW with a period of 9 seconds, and the combined energy is moderate at 461. It’s far from the biggest swell of the window, but it’s the cleanest we’ll see for a while. The break is fairly exposed to the SW, so it’s catching that energy well. Poldhu Cove is inconsistent though, so don’t expect a set every minute, but when they come, they’ll be worth the paddle. Keep an eye out for crowds, as they can be around sometimes.
Saturday the 12th and Sunday the 13th are a bit of a mixed bag. Saturday gets onshore winds again, turning it into a lumpy mess. Sunday morning’s got a 5ft W swell with a 10-second period and a light cross-shore wind, but it’s only marginal – the tide might be playing tricks, and the forecast isn’t confident. The combined energy is still moderate at 498, but it’s not a standout.
The middle of the week, Monday the 14th and Tuesday the 15th, is more of the same – cross-onshore chop and poor conditions. Tuesday afternoon shows a glimmer with a clean cross-offshore wind and a 4ft W swell, but it’s only marginal.
The real standout of the whole forecast is Saturday morning the 19th. That’s the one to circle on the calendar. Glassy conditions, with a NNE breeze so light it’s barely a breath of air. The swell is a solid 4ft from the WNW with a period of 10 seconds, and the combined energy is a moderate 378. The wind will be glassy, and that’s a rare gift. The break is inconsistent, but when it’s glassy like that, it’s a special session. Poldhu Cove is a fairly exposed spot, so it’ll catch that swell just right. It’s a long way out, so keep your fingers crossed the forecast holds.
After that, the last week of the outlook is pretty ordinary. Clean winds on the 20th, 21st, and 22nd but the swell drops right off to under 3ft, with combined energy dropping into the weak range. The 23rd has a long-period 14-second swell from the west at 4ft, pumping the energy up to a strong 638, but it’s cross-onshore and choppy. That’s a shame – that’s a lot of energy for a messy day.
All in all, the best bet is that Friday morning the 11th for a solid clean session, and if you’re feeling lucky, keep your eyes on the 19th. It’s a waiting game, but it tends not to stay poor for long.

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.
