The Lowdown

Right then, let’s have a look at what’s on offer for the next couple of weeks.

To be straight with you, it’s a grim run for most of the forecast. We’ve got a long stretch starting from Saturday the 12th right through until Tuesday the 22nd where the surf is just not worth paddling out for. The wind is all over the place, mostly cross or onshore, and the water’s a touch warmer than normal at 64°, but the quality is shot. The swell energy is there at times – you’ll see moderate to strong readings, like 421 (moderate) up to 937 (strong) – but it’s all blown out. Even on the 15th and 16th of September, when we get some clean offshore wind from the NW with swell heights of 6ft to 6ft and period around 8 to 10 seconds, the wave comment still says *poor surf conditions*. It’s a shame.

Now, there is a little bit of light at the end of the tunnel. On Wednesday the 23rd of September, things finally turn. We’ve got a clean morning with a light ESE breeze, cross-offshore, and a 6ft swell from the west. The energy is weak at 312, but the conditions are described as “clean”. Then Wednesday afternoon gets even better – a gentle offshore wind from the SE, 7ft of west swell, and the wave comment says *expect good surf conditions*. This is the standout. The water temp is still that touch warmer than normal, but who cares when it’s glassy and offering head-high waves. Thursday the 24th morning keeps that clean offshore theme with 5ft west swell and a moderate offshore, but the energy drops a bit.

For the rest of the run into the 27th, it’s back to messy onshore junk with strong energy but terrible shape – 8ft and 15-second swell on Sunday the 27th sounds big, but with strong cross-onshore wind it’s a mess. Not for paddle surfing.

So, if you’ve got patience, Wednesday the 23rd and Thursday the 24th are your window. The rest is a write-off until then.

Information about the Portreath Beach Surf forecast

The above surf forecast table for Portreath Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Portreath Beach can be found by selecting the local surf guide option on the grey menu. Our Portreath Beach 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 (Portreath Beach) 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 Portreath Beach 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.
