The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for this stretch of coast.

We’ve got a tough run ahead. The whole 16-day window is one long, frustrating gap. There’s nothing on offer that’s worth paddling out for. The first few days are completely flat, and even when tiny lumps of swell try to show up, they’re met with nasty wind, onshore slop, or just zero energy. It’s a real desert out there.

The first little whisper of something comes on the 24th of July, with a tiny 0.3 ft swell from the west, but it’s barely a ripple. The energy is almost nothing (3). The water is running much warmer than normal for this time of year at 66°F, but that’s about the only highlight. The wind is light and cross-off, so it’s clean, but there’s nothing to ride.

From the 25th through to the end of the month, we see pulses of weak, short-period swell (4 to 6 seconds) bumping up to about 3 ft, but the wind is swinging between cross, cross-off, and onshore. The combined energy stays low, never cracking 100. It’s messy, poor surf conditions all the way.

The first few days of August are a bit of a tease. The 2nd of August shows glassy conditions in the morning with a tiny 0.7 ft swell from the WSW, but the energy is still weak (9). It’s clean, but you’d be hard-pressed to get a ride.

Then, on the 6th of August, things get a little more interesting but not for the right reasons. The swell picks up to 4 ft from the southwest, with a period of 6 seconds, and the combined energy bumps up to 89 (moderate). But the wind is a fresh cross-onshore at 19 mph, making it lumpy and messy. The setup is more interesting for a kite surfer than a paddle surfer.

Bottom line: this is a blank run. Porth Ceriad needs a proper swell and clean wind to turn on, and it’s just not in the cards. Forecasts can change, but for now, save your wax and wait for the next one.

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.
