The Lowdown

Alright, let’s get real about Portreath Beach. I’m looking at the next 16 days and honestly, it’s a tough watch. The first real chance to get wet doesn’t come until Saturday the 5th of September.

That Saturday morning you’ve got a clean 5ft WNW swell rolling in with a light offshore breeze from the WNW at 6 mph. It’s got a solid 12-second period, so some proper groundswell energy, with the combined energy sitting at 730 — moderate power. The water temp is 64°, about 2° above average for this time of year, so it’s a little warmer than you’d expect. Just a touch. That morning window is your best shot, but the overall call is marginal and crowds are often here, so expect it to be busy.

By Saturday afternoon the wind swings cross-shore and the swell drops to 4ft. Not worth staying in the water.

Sunday the 6th has offshore wind in the morning but the swell is tiny — only 3ft with combined energy of 106. That’s barely surfable.

Monday the 7th sees a big jump in size — up to 8ft WNW with a very long 13-second period and combined energy of 1783 — but the wind is cross-onshore and choppy. That’s going to be blown-out and messy. Too big for beginners, too rough for anyone wanting a clean wave.

From Tuesday the 8th all the way through to the 19th of September, it’s a rough run. Most days have moderate to fresh cross-onshore winds, lumpy conditions, and swell sizes rarely over 3ft, with combined energy often under 200. The period is mostly short, under 10 seconds, so you’re not getting any real drive.

The one glimmer is Sunday the 20th of September. It’s still small — only 2ft from WNW — but the wind is light cross-offshore from the ENE at 6 mph, keeping the surface clean. The combined energy is weak at 77, period is 9 seconds, so it’s not going to be firing. But if you’ve got a longboard or a foamie and just want a clean little glide, that’s your window. Just remember, this is way out at the end of the forecast — promising, but far from certain.

All in all, it’s a lean run. Nearly two weeks of poor to flat conditions with just a couple of very short, marginal windows. This area can go through dry spells like this, and this is one of them. Keep checking back, but don’t hold your breath.

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.
