The Lowdown

Alright folks, Rusty here. Let me be straight with you – this is a tough one. We’re looking at a long, dry spell for the coast, with the first real hope not showing up for a while.

We start off flat. The first few days are a total write-off. Porth Ceriad sees nothing but tiny, weak dribble from the 24th through to the 31st of July. Winds are messy, and the swell energy is pathetic, often in single digits. It’s a real struggle just to find a ripple. The water temp on the 24th is sitting at a balmy 66°, which is a whopping 6° warmer than usual for this time of year – that’s very unusual, but there’s no surf to enjoy it in.

We finally get a pulse of energy on the 1st of August. The morning brings a 2ft swell from the WSW, but it’s onshore and messy. The afternoon sees a slight improvement with a 3ft swell from the same direction, but it’s a short-period 11 seconds and cross-shore. The combined energy jumps to 149 (moderate), but conditions are still ordinary. It’s not worth getting wet for.

The real tease comes on the morning of the 2nd of August. The swell is still a modest 2ft from the WSW, but the wind goes glassy. The water is like a mirror. It’s the first time the report says “surfable waves but very ordinary conditions.” It’s frustrating because it’s so close to being good, but the swell is just too weak and short-period (10 seconds) to offer any real punch. The combined energy is only 62 (weak). That’s the best of a bad bunch right now.

After that, the wind goes to hell again. The 4th of August brings howling near-gale winds – 31 mph onshore and 34 mph cross-onshore – with a 3ft swell that’s blown to bits. The combined energy hits 111 (moderate) but it’s completely unsurfable. That’s more of a kite-surfing setup than a paddle session.

The 5th of August is the biggest swell of the whole forecast, but it’s a total mess. We get a 6ft swell from the SW, but with a short period of just 6 seconds. The combined energy is strong at 221 to 265, but the wind is a fresh cross-shore, leaving it lumpy and choppy. That size is getting too big for beginners, and the quality is just not there for anyone.

After that, we fade back into small, weak, and choppy conditions through to the 8th of August. The offshore winds on the 8th are clean, but the swell is a pathetic 1ft with almost no energy. It’s a clean flat spell.

The Standout (with a caveat): Honestly, the only window that’s even worth a look is the morning of the 2nd of August. The glassy conditions at Porth Ceriad are a rare treat, but the swell is tiny. If you’re desperate for a longboard glide and don’t mind a dribbly wave, that’s your shot. It’s a beginner-friendly spot, and the crowds are often there, so expect company. Just don’t expect any power.

This is a tough run, folks. These blank spells happen. We’ll just have to wait for the next proper groundswell to align with some clean wind.

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.
