The Lowdown

Alright, grab a coffee mate, let’s have a look at what’s cooking. It’s a tough stretch ahead, I’ll be straight with you. The whole 16-day window is looking like a write-off for any kind of decent surf. We’re looking at a long, flat spell, so if you’ve got other plans, don’t feel bad about pulling the pin.

Porth Ceriad is the only spot we’ve got on the radar, and honestly, it’s a ghost town. We kick off with nothing on the board, and that’s the story right through to the end of the forecast. The first hint of anything rideable doesn’t show up until the 10th of September, but even then, we’re talking about a tiny window. On the Thursday morning, the wind finally goes light and clean with a cross-off breeze, and the swell shows up at 5 ft from the WSW with a period of 7 seconds. The combined energy reads a moderate 279 (just a moderate push), and the water temp is a very unusual 65°—that’s much warmer than you’d expect for this time of year. It’s a break that’s fairly consistent and exposed, facing a SW swell, so it gets what’s coming.

For that Thursday morning, it’s going to be clean and surfable, but don’t get too excited—it’s only a brief moment. The afternoon drops off to 4 ft and the energy halves. After that, it’s back to the doldrums. Friday the 11th is tiny and clean but you’d be fighting for scraps. The rest of the second week is a complete bust—flat, blown out, or just too small to bother. There’s one late blip on Sunday the 13th afternoon with a gentle offshore, but the swell is a mere 1 ft. That’s not a session, that’s a paddle.

So, bottom line: there’s no standout, no hidden gem, just one or two hours of half-decent conditions on the 10th of September morning if you’re desperate. The rest is a long dry spell. It’s more normal for this part of the world to have these blank runs, but it’s grim. I’d keep an eye on the charts, but for now, I’d find something else to do.

Rusty.

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.
