The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Poldhu Cove.
Straight up, the first week is a bit of a write-off. We’re looking at a solid gap of poor conditions until around the middle of the second week. The good news is that things start to clean up nicely after that.
The first surf worth paddling out for looks to be on the morning of Sunday the 15th of September. The wind will be light and offshore from the NE, cleaning up a 3ft groundswell rolling in from the W with an 11-second period. It’s not huge, but it’s clean, and the water is a touch warmer than normal for this time of year at 64°F. The combined energy is sitting at 326 (moderate), so there’s enough push for a fun session. The afternoon looks even better with glassy conditions and the same size swell. This is the standout window – small but clean.
The other real highlight comes on Thursday the 17th of September. Morning offshore winds from the ENE will be grooming a 5ft W swell. The period is a short 8 seconds, so it’ll be a bit lumpier and more suited to a beach break setup, but the clean conditions and moderate combined energy of 323 should make for some fun, punchy waves. This is probably the biggest clean swell of the whole outlook.
Earlier in the week, on the 14th, there’s a tiny glassy bump of 2ft with a long 13-second period, but it’s barely surfable unless you’re on a log. The rest of the first week is dominated by onshore and cross-shore winds, choppy seas, and poor surf quality. The wind is just too messy and the swell is either too small or too short-period to be any good.
So, to sum it up: the first 10 days are a bust. The best bets are the clean, offshore days on Sunday the 15th and Thursday the 17th of September. That’s your window.
Stay frothy,
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.

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.
