The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the cards for Poldhu Cove.
The next couple of weeks look pretty lackluster, to be honest. The first week is a real struggle with weak, short-period swell and messy wind almost every day. There’s a big gap of several days with no real surf to speak of. We’re looking at the usual small stuff, but nothing is coming together properly. The water is sitting at 66°F which is a touch warmer than normal for this time of year, so that’s one small comfort.
Monday 10th August kicks things off with a tiny 2ft swell from the WNW, but the period is a short 6 seconds. The wind is a light cross-offshore at 6 mph, which keeps the surface clean, but there’s next to no energy (67) in the water. It’s just small and weak. The afternoon drops even further to 2ft.
Tuesday 11th and Wednesday 12th offer a bit more size, with the swell picking up to 3ft on Wednesday morning showing a touch more energy (138), but the wind is firing from the ESE at 15 mph, making it a cross-off breeze. The period is still short, so the waves lack punch. It’s not terrible, but it’s not worth paddling out for.
The best chance in this first week comes on Thursday 13th August. The morning swell bumps up to 4ft from the west with a solid 11-second period, giving us some decent energy (326). The wind is from the NW at 12 mph, a clean cross-off. This is the only window that looks even remotely interesting, but it’s still a gamble with marginal conditions. The afternoon turns cross-shore and lumpy.
From there, the wind stays moderate and cross-off, but the swell drops back to under 3ft and the period drops to 8-9 seconds. The energy is low (162-165). It’s just not on.
Saturday 22nd August brings a surprise – a glassy afternoon with 5ft of swell from the WSW, but the period is a short 5 seconds. The energy is moderate (153) but the waves will be fat and weak. Still, a glassy 5ft wave is better than a windy 2ft one.
Now, Sunday 23rd August is the standout, but it’s a long way out. The morning kicks up with a serious 10ft swell from the west, with a 10-second period, pumping a massive 1691 in energy. That’s a big, powerful, raw swell. However, the wind is a moderate cross-off from the NNW at 15 mph. The water temp will be similar. This is a big, expert-only day. The afternoon sees the swell drop to 8ft but the wind turns cross-shore and lumpy with a fresh breeze. If you’re an experienced surfer, that Sunday morning is the one to circle on the calendar, but it’s two weeks out, so keep your fingers crossed.
The rest of the second week is a write-off with small, wind-affected waves.
So, there’s not much to shout about. The one real standout, if it holds, is the big swell on Sunday 23rd August. Other than that, keep your expectations low and your eyes on the forecast.
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.

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.
