Alright crew, Rusty here. Let’s call it like it is—this 16-day outlook for Porth Ceriad is a real bummer. We’re looking at a whole lot of flat, tiny surf, so don’t be in a hurry to wax up.
From Tuesday the 7th all the way up to Wednesday the 22nd, it’s pretty much nothing but ankle-high slop. The energy readings are mostly in the single digits—like Tuesday the 7th afternoon, we’ve got a 1ft swell from the NW, but the energy is only 6 and the period is a short 4 seconds—total junk. Water temps are running about 63°, which is 5° warmer than usual for this time of year, so a very warm anomaly.
The only time we see any real size is late in the game. On Wednesday the 22nd afternoon, the swell jumps to 4ft from the WSW, with energy up to 71. But the wind is cross-shore, kicking up chop, so it’s not clean. There’s just no session here that you’d want to tell your mates about.
If you’re a beginner and just want to get wet, Monday the 13th morning might offer a tiny 1ft wave from the East with a light offshore breeze, but the period is only 3 seconds—that’s wind chop. For the rest of us, it’s a long, dry stretch with nothing to chase. Stay patient—forecasts change, but for now, it’s a flat spell.
Signing off, 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.
