Alright, Rusty here. Let’s take a look at what’s shaking for your local break.

To be straight with you, it’s a pretty flat outlook for the next two weeks. We’ve got a long stretch of nothing, with barely a bump to get excited about. The first few days are dead calm, with tiny swell and clean but empty conditions. The first real chance to get wet doesn’t show up until the very end of the run, and even then, it’s a small one.

The forecast only really shows a potential pulse of activity around the 21st of July. That’s over a week away, so don’t get your hopes up too high, but it’s the best we’ve got. For the whole 16-day window, we’re looking at a big gap of nada until that Tuesday.

Porth Ceriad is the only spot on the map, and it’s a beginner-friendly, exposed beach that likes swell from the SW. The water is sitting at 63°, which is *much warmer than normal* for this time of year—that’s a seriously unusual anomaly of nearly 5° above average, so you’ll be comfortable in a spring suit or even boardshorts.

The standout moment—such as it is—comes on the afternoon of Tuesday the 21st of July. We’ve got a 2ft swell from the SW, with a clean 6-second period. The combined energy is a weak 35 (moderate), but the wind is a gentle offshore from the NNW, which will keep the surface glassy. It’s small, but it’s the only window where the wave state is worth a look. The vibe is clean, the crowd factor is “often” here, so you might have a few buddies out, but for a Tuesday afternoon, it’ll be quiet enough.

Don’t hold your breath for the rest of the fortnight. The swell stays tiny, mostly under 1ft, with periods all over the place. The wind is often offshore, which is a tease—clean conditions with no waves to ride. It’s a classic case of “good wind, no swell” for this area. If you’re a kite surfer, the steady offshore winds on the 17th and 18th might get your interest, but for a paddle surfer, it’s a dry spell.

The only real potential is that 21st July window. It’s not a day to call in sick for, but it’s the one chance to get a few clean little ones. Beyond that, forecasts can change, but as it stands, it’s a waiting game.

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.
