The Lowdown

Alright, let's get straight into it. It's a bit of a flat spell ahead for us, no two ways about it. The next two weeks are looking pretty quiet, so keep those expectations in check.

To be honest, the first real chance of anything rideable doesn't show up until Thursday, the 23rd of July. Even then, it's a tiny pulse of 1ft from the WNW with a super short period of 3 seconds. That's hardly enough to get a longboard moving, and the cross-off wind from the NW won't do much to help it. The wave energy is a measly 2 (weak).

We get a little bump on Friday, the 24th of July. The morning sees a slightly better 1ft swell from the NW with a 4-second period, but the wind is cross-shore from the WSW, so it's going to be a bit bumpy. The combined energy is still weak at 13.

The only period that might raise an eyebrow is Saturday, the 25th of July. The morning brings a 2ft swell from the SW with a 5-second period. The wind is a clean cross-off from the NNW at 18 mph, so it'll be glassy. The wave energy is a bit more present at 24 (weak). This is probably the best of a very flat bunch for Porth Ceriad, a beginner-friendly spot that's fairly consistent and exposed to the SW. The water temp is about average for this time of year, so nothing wild there.

The rest of the outlook is a write-off. After the 25th, it drops back to tiny, under 2ft slop, with weak energy and poor surf conditions. The crowds are often around here, but honestly, with this lack of swell, it won't be an issue.

So, to wrap it up: if you're desperate for a paddle on the 25th, you might get a few small, weak waves. But honestly, this is a long, flat spell. Keep the board in the garage and wait for the next system.

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.
