Table - best surf conditions forecast for Portreath Beach over the next 16 days.
Right then, folks, Rusty here. Let's have a look at what we've got coming up for Portreath Beach. I've got to be straight with you – the next couple of weeks are looking grim for a proper surf.
We're starting off with a dry spell that runs all the way from Friday, July 10th, right through to Saturday, July 18th. That's over a week with nothing worth paddling out for. The water temp's sitting at 62°, which is about a degree and a half warmer than usual for this time of year – pleasant enough if you're just having a dip, but not helping the waves any.
The combined energy is very weak, barely cracking 100 (119) on the first afternoon, and then it just fades away into single or low double digits for days on end. The swell is tiny, mostly under 3 feet, and the period is short – often around 6 or 7 seconds – so there's just no push behind it. The wind, while often cross-offshore during this stretch, is blowing hard, sometimes up to 25 mph on Monday the 13th, which just makes a mess of what little bump there is. It's a classic case of "poor surf conditions" all the way.
Now, there is a flicker of hope towards the very end of the run, but it's for experienced crew only. On Friday, July 24th, the swell really fires up, but way too much. We're talking a solid 13 to 15 foot swell from the west, with a nice long period of 11 to 12 seconds. The combined energy is massive, over 3500 (3527) and even 5630 – that's a serious ocean. The wind is offshore from the ESE and SE, which would normally be absolute perfection. But mate, this is simply too big for Portreath Beach. The finder even says it's predicted to be too big for the break. It'll be a washing machine, only for the absolute best, and even then, you'd be taking your life in your hands.
After that, it backs off a touch on Saturday the 25th, with a 10 to 8 foot west swell, but the wind swings onshore and the conditions turn choppy and marginal. So, no good options here, I'm afraid.
Hang tight. The forecasts can change, but for now, it's a blank run. The only bit of size we get is just plain dangerous.
Rusty.

A general guide to surfing at Portreath Beach can be found by selecting the local surf guide option on the grey menu.

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.
