The Lowdown

Alright folks, Rusty here with the straight story on Porth Ceriad.

Gotta be honest with you – this 16-day stretch is a total dud. We’ve got a massive gap of flatness starting right now. First up, Saturday July 25th, we’ve got a tiny 1ft swell with a cross-onshore breeze and a combined energy of only 5. It’s choppy and useless. That’s the whole story for the foreseeable. Sunday July 26th brings the biggest bump of the period – a 4ft swell from the west with clean wind, but the combined energy is still just 71, and it’s rated as poor surf conditions. That’s the high point, and it’s sad.

The whole first week drifts by with nothing but flat, clean but empty water. The water temp on that first Saturday was about 5° warmer than usual for this time of year, which is notable, but it doesn’t put any waves under you.

We get the best chance on Tuesday August 4th. A 1ft southwest swell with a period of 8 seconds, a clean offshore wind, and a combined energy of 23. That is the absolute standout, and it’s still a very weak, small wave. After that, it just fades back to flat, tiny dribble with a few long-period pulses on August 9th that offer nothing.

For a break that’s fairly consistent, this is a weird, dead run. The forecast is solid for the near term, so it’s not changing. The second week continues the same theme: clean conditions, no surf. This is kite territory for now.

Don’t get your hopes up. Check back in a week.

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.
