Alright, let me be straight with you. Looking at this 16-day window for Porth Ceriad, it's a tough one. There's barely a breath of surf worth getting wet for, and there's a long gap with absolutely nothing on offer.
From now, the first few days are just flat. There's a tiny, weak pulse showing around Thursday the 10th into the weekend, but it's ankle-snappers at best. After that, it looks like we're looking at a blank run for several days – nothing of any real size until maybe mid-week the following week, which is over a week away, and even that is tiny and inconsistent.
Let's talk about the only window that's even worth a mention. Around Friday the 12th and into the weekend of the 13th and 14th of July, we might see a trace of swell creep in. We're talking a paltry 0.3 ft, mainly from the west. The combined energy is next to nothing, barely registering, so don't expect any push. The saving grace is that the wind turns offshore or cross-offshore from the north-northwest, with some glassy periods on the morning of Friday the 12th. So, the water will be clean, but there's simply no wave to ride. For a beginner-friendly spot like Porth Ceriad, this is a real bum-out.
Honestly, with such tiny, weak swell and mostly clean but empty conditions, the setup here over the next week would be more interesting for a kite surfer than a paddle surfer. You'd be better off waiting for a proper forecast.
Hang in there, but I wouldn't hold my breath for this stretch.

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.

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.
