The Lowdown
Alright, folks. Rusty here. Let's talk about what's cookin' for the next couple weeks.
Gotta be straight with you – this forecast for Poldhu Cove is a slow burner. We're looking at a real dry spell at the start. From the 21st all the way through the 25th, it’s basically flat. Swell heights are barely 1 ft, and the combined wave energy is weak, sitting in the 30s (31-49). The wind changes every day, but there's just no juice in the water. You’re better off waxing your board and waiting.
Things finally get interesting on Sunday the 26th. The swell jumps to 8 ft in the morning, coming from the WNW with a period of 8 seconds. The combined energy kicks up to 660 (660), which is a solid, powerful push. The morning wind is a cross-offshore from the NNW, keeping the waves clean. But here’s the thing – at 8 ft, this is expert territory. It’s a short period, so it'll be a bit fat and dumpy, but for the brave souls, there’s grunt in it. The wind shifts cross-shore in the afternoon, so the morning is the clear window.
The real standout is Monday the 27th. The morning delivers 6 ft of WNW swell, with that same clean cross-offshore breeze from the NNW. The energy is still strong at 441 (441). It’s a solid size, but manageable, and the conditions should be glassy. This is your best session of the whole 16-day run. Water temp is about average for this time of year.
After that, it’s a steep drop-off. The rest of the week and into early August is small, messy, and onshore. There’s a brief chance on the morning of the 29th with a light easterly cross-off, but the swell is only 2 ft. It’s rideable, but nothing to write home about.
Bottom line: first week is a bust. The big highlight is the morning of Monday the 27th of July. Sunday the 26th morning has the biggest waves, but it’s for the experts only. The second week looks like a bust too, with small, choppy conditions.
Rusty.

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.
