The Lowdown

Right then, folks, let's have a look at what's cookin' for Porth Ceriad. I gotta be straight with you right from the off – this 16-day window is a bit of a desert for us. We're looking at a whole lot of flat, small, and messy energy, with a glimmer of something worthwhile way out there.

The water is currently a balmy 66°, which is a massive 6° warmer than what we’d usually expect for this time of year. That’s really unusual, so you'll be in boardies or a shorty for sure.

The first few days are a write-off. Friday the 24th and Saturday the 25th see nothing but tiny, weak waves. The combined energy is pathetic, barely registering 6 (6), and it's either cross-off or cross-on with a chop. Sunday the 26th through to the end of the month? More of the same. Flat spells and onshore slop. There's a big gap of almost no surfable recommendations. We're talking a solid week of nothing good.

There's a tiny flicker of life on the 1st of August, with some 0.4 ft swell from the SW creeping in, but it's still weak. The real story, and the only one worth getting even a little excited about, is the morning of Saturday the 8th of August. We've got a pulse of 6 ft swell from the SW, with a period of 7 seconds. The combined energy jumps up to 331 (331) – that's moderate, but it's actually the best we'll see. The wind is forecast to be glassy, which is a massive positive. It'll be clean. But, it's a short-period swell, so it won't have that grunty groundswell shape. The wind is light and glassy, so the clean conditions will be the main draw.

Honestly, that morning of the 8th is the only standout. For a beginner-friendly spot like Porth Ceriad that's exposed to the SW, this is a promising little window. The 6 ft swell is more than 5 ft, so it's a bit too much for total beginners, but it's still manageable for anyone with a bit of time in the water. Word of warning: the crowds can be *often* here, so get down early. The forecast is a long way out, so take it with a pinch of salt, but it's the only glimmer on the horizon. For the rest of the time, you're better off checking the wind forecast for a kite session.

Information about the Porth Ceriad Surf forecast

The above surf forecast table for Porth Ceriad provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Porth Ceriad can be found by selecting the local surf guide option on the grey menu. Our Porth Ceriad 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 (Porth Ceriad) 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 Porth Ceriad 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.
