The Lowdown
Alright, Rusty here again. Let’s talk about Porth Ceriad – but this time in feet and miles.
It’s a real bummer, folks. From Monday 20 July all the way through Tuesday 4 August, there’s nothing worth riding. Sixteen days of flatness. Every session in the forecast is poor surf conditions. Even when the wind is light offshore or glassy, there’s simply no swell. The biggest wave we see is about 5 ft on Sunday 26 July morning, but it’s a short-period windswell with only 5 seconds between waves and combined energy of just 124 – weak and junky. Not worth the effort.
Porth Ceriad is normally a fairly consistent beginner spot, exposed to SW swells, so this quiet spell is unusual. The wind is often offshore or cross-offshore, which would be perfect if there was any swell. But there isn’t. Expect a long blank run. The good news is this break doesn’t usually stay flat for long, so forecasts can change. Keep an eye on it, but for now, leave the stick at home.
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.
