Hey, Rusty here. Right now, Saturday afternoon, the ocean’s completely flat at Porth Ceriad. The water’s sitting at 64° which is a solid 6° above normal for this time of year – properly warm, but no swell to enjoy it. The whole 16-day window looks pretty grim. Sunday morning, Sunday afternoon, Monday, Tuesday – all tiny 0.3ft dribbles, mostly cross-off winds, zero energy. The only slight bump comes on Saturday 25 July afternoon, with a 3ft swell from the WSW, but it’s onshore and the conditions are poor. Combined energy is still just 27 – weak. Wednesday 15 July morning has a tiny 2ft ESE swell but that’s about it. Most days the swell is either absent or below 1ft, and the wind is rarely clean. There’s a glassy moment on Friday 17 July morning with 1.0ft from the SW, but again, no real push. The rest of the period is flat or near-flat, with a few offshore winds offering clean surfaces but no waves. Porth Ceriad is a beginner-friendly break, fairly consistent, and it needs a decent SW swell to light up – we’re just not getting that. So for now, it’s a long flat spell. Forecasts can change, and this spot usually delivers when the swell kicks in, but for the next couple of weeks, don’t bother packing your board. 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.
