The Lowdown
Alright, folks. Rusty here. Let’s break down what’s in store for Poldhu Cove over the next couple of weeks.
Honestly, it’s a quiet start. There’s a big gap with no real surf to speak of right from the beginning. Nothing worth dragging your board out for until around the 26th of July. The swell is tiny and the conditions just aren’t playing ball. We get a few days of clean, glassy conditions on the 21st and 22nd, but the waves are only 1 feet, so it’s barely a ripple. Not worth the effort.
The first real sign of life shows up on the morning of the 26th of July. The swell picks up to 5 feet from the WNW, with a short period of 7 seconds, and the wind is a clean cross-off from the NNW. The combined energy is moderate at 188, so there’s a bit of push. It’s still marked as poor surf conditions, but this is the first time the size and wind line up. The afternoon sees similar energy at 205, but the wind swings cross-shore and gets lumpy, so the morning is your best bet here.
The 27th of July has the biggest swell of the whole run, hitting 5 feet from the WNW with an 8-second period and 335 combined energy. That’s a moderate pulse, but it’s blown out by a fresh cross-shore wind. The water temperature is a notable 67°F with a 5°F anomaly – that’s much warmer than usual for the time of year, so you won’t need a thick wetsuit.
The 28th of July drops back to 3 feet swell, but with a clean cross-off wind in the afternoon, it’s a bit cleaner. The 29th has a glassy morning with 2 feet swell, but it’s tiny. From the 30th onward, the swell stays small and the wind gets messy again, with onshore winds and rain by the 1st of August.
If you’re really itching for a session, the standout moment is the morning of the 26th of July. It’s not great, but it’s the best we’ve got. The swell is 5 feet from the WNW, the wind is clean off the land, and the water is warm. The break is inconsistent, so don’t expect a wave every minute, and crowds are possible. For a beginner, the 5 feet might be a bit much, and the period is short, so it’ll be a bit crumbly. For the rest of the run, it’s a lot of waiting for nothing.
Rusty.

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.
