The Lowdown

Alright folks, Rusty here. Let's take a look at what Poldhu Cove has got cooking for us over the next couple of weeks.

Honestly, looking at the whole picture, it's a bit of a frustrating run. There are windows where the swell shows up, but the wind just won't play ball. Most of the time it's onshore or cross-onshore, mucking up what could be decent waves. There's no real standout, screaming “surf me” session, but let’s break it down day by day.

We kick off Thursday the 10th with some swell, but it's small and messy. The water is sitting at a touch warmer than normal for this time of year, coming in at 64° with a 3° anomaly. The wind is howling onshore from the SSW at 19 mph, so the 3 ft swell from the WSW with a short 5-second period isn't going to be much fun. The combined energy is weak (93).

Friday the 11th shows a bit more size – 5 ft from the W with a 9-second period on Friday morning – but the wind is a cross-shore from the NW, which isn't ideal. The energy is building (380), but the report calls it marginal, not good.

The weekend and early next week are a write-off. Saturday and Sunday see building swell, but it's all onshore or cross-onshore wind, making it choppy and poor. Monday the 14th is flat and weak. The only flicker of hope is that the swell is fairly consistent, but the quality just isn't there. There's a gap of nothing good through to the middle of the following week.

We get a bit more size on Tuesday the 16th with a 8 ft swell from the WNW early, and the wind is actually a clean cross-offshore from the NNW. The combined energy is high (978), so there's power. But this is 8 ft, which is getting into expert territory and the report flags it as marginal, not a green light.

Later in the week, Wednesday the 23rd and Thursday the 24th have some potential, but it's a long way off. On Wednesday morning, the 23rd, we see a clean cross-offshore breeze with a 4 ft swell from the W, but the period is a very long 13 seconds. That long period can make a beach break like Poldhu Cove close out straight, so watch out for that. The energy is solid (513). Thursday the 24th has a bit more size at 5 ft but a weak 7-second period and a light onshore breeze, so it’s still marginal.

For the best on offer over the whole period? It's a tough call, but I'd have to point to the morning of Wednesday the 23rd. It's a long way out, so take it with a pinch of salt, but with a 4 ft swell, a 13-second period, and clean cross-offshore wind from the N, it might just line up for a few fun ones at this exposed spot. You'll want a step-up board for that long-period energy, and you’ll be hoping it doesn't close out. The other slight nod is Wednesday the 16th morning, but that 8 ft is only for the experienced.

Signing off,
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.
