The Lowdown

Right then, let’s have a look at what’s on the cards for Portreath Beach over the next couple of weeks. I’ll be straight with you, it’s a bit of a mixed bag, and you’ll need to pick your moments.

The main issue is the wind. For most of the coming days, we’ve got a strong onshore or cross-onshore breeze from the north-west, and that’s going to keep things messy. The water temperature is sitting at 65°F, which feels a touch warmer than normal for this time of year – not a game-changer, but a nice little bonus.

The best bet in this whole forecast is the morning of Tuesday the 28th of July. It’s a small one, with a WNW swell pushing in at about 3ft, but the wind is glassy – dead calm from the SSE. That’ll make the waves clean as a whistle, even if they’re not big. The swell period is 9 seconds, so it’s got a bit of shape to it. The combined energy is weak, sitting at 110, so it’s not going to be a big day, but for a clean, cruisey session on a log or a funboard, that’s your window. Keep an eye out for crowds though – it says ‘often’ busy there, and small clean waves will pull a few locals out.

After that, we hit a long, dry spell. From the 29th of July right through until the 9th of August, the guidance keeps telling me the surf conditions are poor. The swell drops right off, mostly under 3ft, and the wind just won’t let up. There are days with a light offshore in the morning on the 29th and 31st of July, but the swell is tiny – 2ft – and the period is short. Not worth getting wet for.

Then, on Sunday the 9th of August, we see a bit of life return. A WNW swell of 6ft to 7ft rolls in, with a period of 7 seconds. That’s a decent size, but the period is short, meaning it’ll be a bit bumpy and fat. The wind is still onshore from the NW at 15 mph, so the quality will be poor. The energy jumps up to 354 and 414 (moderate), so there’s some push, but for the conditions, it’s a tough sell. This one is for the experienced crew only – that swell over 5ft is too much for beginners, and the messy wind will make it a battle.

Honestly, if you’re keen for a paddle, that Tuesday the 28th of July is your standout. Everything else is either too small, too windy, or just plain ugly. For the rest of the run, it’s a lot of nothing, which isn’t unusual for the area when the wind parks itself in the north-west. Keep an eye on the forecasts – it tends not to stay poor for long.

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.
