The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We're looking at a pretty grim start, I'm not gonna lie. For the first week or so, it's a real struggle. The swell is tiny and the wind is all over the place. We've got a solid gap of nothing worth paddling out for from Friday the 7th right through to the 11th of August. The waves are just too small, often under 1.3ft, and when there is a bit of a bump, the wind is mostly onshore or cross-on, making it a messy, choppy affair. It's a write-off.
Things start to show a tiny pulse of life on the morning of Wednesday the 12th. We're looking at a small 2.6ft swell from the west with a 10-second period, and the wind is a clean cross-off from the east. The energy is still weak, only registering 126, and the conditions are "very ordinary," but it's the first time all week you'll see a clean face. It's not a standout, but it's a glimmer of hope after a long, flat spell.
The real standout, the one that gets the heart pumping a bit, is looking like Friday the 21st of August. Now, that's a long way off, so take it with a pinch of salt, but the charts are showing some promise. The morning session is where it's at. We've got a solid 6.6ft swell thumping in from the west-northwest, with a period of 9 seconds. That's a decent amount of power, with the combined energy hitting 600 (moderate wave energy). The wind is a light, clean cross-off from the south-southeast, which is a dream scenario for Portreath Beach. 6.6ft is getting up there, so it's not for the groms, but for the intermediates and up, this is the pick of the entire forecast. The water temperature is sitting at 64.8°, which is a touch warmer than normal for this time of year, so you might even get away with a thinner suit.
The rest of the second week is a bit of a mixed bag. The afternoon of the 21st gets a bit wind-affected with a stronger cross-off, and the following days drop back down in size and get messy again. But that Friday morning is the window. If you've got the patience to wait, it could be worth it.

A general guide to surfing at Portreath Beach can be found by selecting the local surf guide option on the grey menu.

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.
