The Lowdown

Right then, let’s have a look at what’s on offer for the next couple of weeks.

To be straight with you, it’s a pretty grim run for Portreath Beach. The surf just isn't showing up with any real quality, and the wind is playing havoc most of the time. We’re looking at a long stretch of nothing much to get excited about, with the best of the conditions being the odd clean morning here and there, but with tiny, weak waves.

The first real chance of something rideable comes on Monday the 3rd of August. The morning session is your pick. We’ve got a small 3 ft swell coming from the WSW with a period of 9 seconds, which gives it a bit of shape. The combined energy is weak (85), but the wind is a light cross-offshore breeze from the ESE, keeping the surface clean. It’s surfable, but very ordinary. The afternoon sees the wind swing onshore and mess it up.

After that, we go back into a dry spell. The morning of Tuesday the 4th is almost glassy with light winds from the NW, but the swell has dropped to a pathetic 2 ft from the SW. It’s clean, but there’s nothing to ride.

We then hit a proper gap. From the 4th through to the 10th, the north-westerly winds are onshore or cross-onshore frequently, and the swell is small and weak. The best we see is a 4 ft swell on the afternoon of the 7th, but it’s a short-period 6-second wind swell from the SW, combined with 25 km/h cross-onshore winds. The energy is there (125), but it’ll be a choppy, messy mess. Not worth a paddle.

The most promising window, though still not a classic, is Monday the 10th of August. The morning starts with a light offshore breeze from the SE, a tiny 2 ft WNW swell, and clean conditions. It’s small. The afternoon is better: a 2 ft swell from the WSW with a longer 10-second period, and the wind staying offshore from the SE. The combined energy is still weak (86), but the clean, offshore conditions (gentle offshore and clean) mean it’ll be the best looking surf of the whole period. The water temperature is a touch warmer than normal for this time of year, sitting at 65°.

The 11th of August also sees offshore winds, a touch stronger, with a 3 ft WSW swell in the morning, but the energy is low.

To be honest, if you’re desperate for a paddle, Monday 10th afternoon at Portreath Beach is the one standout, but don’t expect barrels. The swell is small, the direction is from the WSW which is okay, but it’s not the optimum NW. It’s a runner for the best of a bad bunch.

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.
