The Lowdown
Right then, let’s have a look at what’s on the cards for Portreath Beach over the next couple of weeks. Straight up, I’ve got to be honest with you – it’s a pretty dire stretch for a while. The wave comment for the entire 16-day period is "poor surf conditions," so the board’s staying on the car for a bit.
We start off with a real gap. From Friday the 17th of July right through to the end of the month, there’s just nothing worth paddling out for. You’re looking at a solid two-week wait for anything that might hold up. The water temperature at the start is sitting at 63°, which is a touch warmer than normal for this time of year (an anomaly of 2°), but that’s about the only positive.
The first sniff of something that might be rideable comes right at the end, on Saturday the 1st of August. The morning shows a 5ft swell from the WNW with a period of 6 seconds, combined energy of 177 (moderate). The afternoon drops slightly to 4ft from the same direction and a period of 6 seconds, energy at 151 (still moderate). But here’s the kicker – it’s blowing cross-on from the NNW at 12-16 mph. That’s going to chop it up and make it messy. Even if there’s a bit of size, the conditions will be poor.
It’s exposed and the optimum swell direction is from the NW, so when the WNW swell arrives it’s close, but that onshore wind is a dealbreaker. The crowds at Portreath Beach can be often, but honestly, with this forecast, you won’t have to worry about the lineup. The setup looks far more interesting for kite surfing than paddle surfing given the cross-onshore winds and lumpy conditions. Nothing here is a standout for a surfer.

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.
