The Lowdown
Right then, let’s have a look at what’s on offer for Poldhu Cove over the next couple of weeks.
Mate, I’ll be straight with you – the start of this forecast is a bit of a write-off. We’ve got a fair bit of swell coming through, but the wind is just not playing ball. It’s a frustrating pattern, but don’t lose hope, because there’s a little window of pure magic right at the end.
First up, Saturday morning, September 5th. We’ve got a 6ft swell from the west, with a 12-second period bringing in some moderate energy (818). The water is a touch warmer than normal at 64°. The wind is light and cross-shore, which is okay, but the report says it’s marginal. The swell is a bit strong for beginners at over 5ft. Honestly, it’s not the best of the window.
The rest of the first week is a bit of a heartbreaking story. We get a jump in size on Monday, September 7th with a 8ft WSW groundswell. The period is a long 13 seconds, and the combined energy is strong (1724). That’s a lot of power, but the wind is a moderate cross-onshore, making it choppy. It’s really only for the experts at that size, and the wind is ruining it. The same goes for Tuesday and Wednesday – there’s swell, but the conditions are just messy.
We then hit a real dry spell. From Thursday, September 10th right through to Monday, September 14th, the wind is either too strong or onshore, and the swell drops off. The waves get small and the reports are all poor. There are a few days there with nothing at all worth paddling out for.
Then, out of nowhere, things change. Tuesday, September 15th is a standout. On the morning, we have glassy conditions – that’s dead calm, offshore wind. The swell is tiny at 1ft, but it’s a clean, long-period groundswell from the west (12 seconds). The energy is weak (69), but for a longboard or a foiler, that’s going to be a beautiful, clean session. It’s a rare, inconsistent spot, but when it’s glassy like this, it’s special.
The real star of the show, though, is the following weekend. Friday, September 18th through to Sunday, September 20th. We’ve got a consistent 2ft to 3ft swell from the west-northwest. The wind is offshore or cross-offshore, and clean. The water is clear, the air is still. The combined energy is still low to moderate (around 151), but the conditions will be perfect. Saturday, September 19th afternoon is the peak: glassy conditions, 2ft of swell, and a clean, peelable wave. It won’t be big, but it will be some of the best, cleanest surf you’ll find in this window. There’s a chance of crowds on the weekend, but for that quality, it’s worth it.
So, to sum it up: the first ten days are a washout. Hang tight, because the second week, particularly the 15th and the 18th-20th, offers some real gems. The standout is Saturday, September 19th afternoon – get on it.

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.
