Right then, let's have a look at what's on the cards for the next couple of weeks around Portreath Beach. I'll be honest with you, it's a bit of a flat spell to start, and frankly, a frustrating outlook overall.
The next week or so is looking pretty lacklustre. We've got a lot of days with onshore winds and small, weak swell. There's a pretty big gap where you wouldn't even bother paddling out. From Saturday the 4th right through to Tuesday the 8th, the swell is tiny – under 3ft – and that combo of weak energy (mostly under 200) with onshore winds means poor surf. Not worth your time.
Wednesday the 8th morning is the first flicker of something half-decent. The wind swings offshore from the east, light at 6 mph, making things clean. The swell is a tiny 2ft from the west at 9 seconds, so not much push, but it's surfable. The combined energy is only 83, so it's weak, but if you're desperate for a paddle, you could make something work.
The rest of that week into the weekend of the 11th and 12th is mostly blown out with fresh cross-onshore winds and lumpy, choppy conditions. The swell picks up a touch on Saturday the 11th, but with a strong 19 mph north wind, it's messy.
Now, the best bet of the whole outlook, and I mean *the* standout, is looking like Friday the 17th. There's a bit of a pulse of south-west swell coming in. On Friday morning the 17th, we see a 4ft SW swell but with a cross-onshore wind, it'll be a bit chopped. However, the real event is Friday afternoon the 17th. The swell jumps to 7ft from the west, with an 8-second period. The combined energy hits a solid 495, which is a decent wall of water. The catch? The wind is onshore from the WNW at 12 mph, so it's going to be a bit of a battle, and that 7ft is getting into expert-only territory for most. It's not going to be clean perfection, but the sheer size and energy will make it the most powerful session of the fortnight. If you're an experienced local and you can handle a bumpy, powerful wave, that's your window.
Before that, Thursday the 9th through to the 16th is all pretty ordinary. There's a couple of brief windows of clean conditions with offshore winds on the 13th morning and 15th morning, but the swell is tiny – 1ft and 2ft respectively – so it's barely breaking. The water temp is around 61°, which is bang on average for this time of year.
So, in a nutshell: a long, flat, and mostly blown-out week and a half, then a spike of real, heavy, but messy power on the 17th afternoon. Not much to get excited about otherwise.

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.
