The Lowdown
Right then, let’s have a look at what we’ve got. I’m lookin’ at Portreath Beach over the next couple of weeks, and honestly, it’s a bit of a slow burn. The first week is pretty much a write-off for any decent surf.
We kick off Monday the 14th with a small, messy 4ft swell from the west and a cross-shore wind. The water’s a touch warmer than normal for the time of year at 64°, but that don’t help the surf. The combined wave energy is weak (242), and it’s just not worth paddling out. That same poor form hangs around through Tuesday, Wednesday, and Thursday, with winds mostly onshore or cross-onshore, and the swell bumping up to a messy 6ft. The energy gets moderate to strong, hitting 1046 on Wednesday morning, but with those onshore winds and a short, choppy period, it’s all just closeouts and whitewater. For a beach break like this, it’s lookin’ more like a kite surfer’s session than a paddle surfer’s.
We get a little glimmer on Friday the 18th morning – a 6ft swell from the west-northwest, a long period of 13 seconds, and combined energy of 1198 – that’s got some proper power behind it. But the wind is a light cross-onshore. It’s still pretty marginal. Then Saturday and Sunday keep that same cross-onshore wind with a drop in size to 4ft. Not great.
Now, the first proper standout comes in on Monday the 21st. Finally! A clean, glassy morning with a 3ft west swell, 12-second period, and a light offshore breeze from the east-southeast. The combined energy is moderate at 306 and the forecast is for good surf conditions. It’s not huge, but it’ll be clean and lined up. Portreath can be a bit inconsistent, but when it gets that offshore wind on a long-period groundswell, it’ll offer some nice little peelers. Expect a fair few people out if it’s clean, though, because it looks like one of the only decent windows for a while. That good form carries into Tuesday morning with similar 3ft swell and clean cross-off winds, and then Thursday the 24th is the other real highlight. Thursday morning and afternoon look brilliant – a 4ft to 4ft west swell with a long period of 11-12 seconds, light east-southeast and east-northeast winds, and the forecast is for good surf. The energy is moderate to solid (358-463) and the conditions will be clean. That’s the pick of the second week.
After that, things fade out again into the last weekend and into the 16-day window, with small, weak swells and mostly cross-onshore winds. A few clean moments on the 27th and 29th, but the swell is tiny and the energy is very low (24-41). So, in short, the first week is a washout. The Monday the 21st is a good chance for a clean session, but the absolute best bet is Thursday the 24th. Keep an eye on that one.

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.

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.
