The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks down at Portreath Beach.
To be honest, it’s a pretty grim stretch ahead. We’re looking at a solid 12 days with nothing worth paddling out for. The water is sitting at 65°, which is a touch warmer than normal for this time of year, but that’s about the only bright spot for a while.
From Thursday the 6th right through to Monday the 17th of August, it’s all poor surf conditions. The swell is tiny, mostly under 3ft, and the wind is almost constantly onshore or cross-onshore, chopping up whatever little bumps there are. There’s one moment on Saturday the 8th afternoon where the wind goes glassy, but with a 1ft, 10-second swell from the WNW, it’s just not enough to get excited about. The combined energy is weak (40), so you’re better off staying dry.
The first real glimmer of hope doesn’t show up until Tuesday the 18th of August. We’ve got a 3ft, short-period swell from the north, and the wind goes glassy in the morning. The energy is still weak (140), but it’s surfable. That’s your best bet in the whole outlook. It’s not going to be world-class, but with glassy conditions, you might snag a few clean ones if you’re patient.
After that, we’re right back into the wind and small, messy junk. The swell picks up a bit into the following week, but the wind is howling cross-shore and cross-onshore, making it a mess. By the 20th and 21st, we’ve got 5ft of short-period swell, but with a strong breeze and rain, it’s more of a kite-surfing scene than a paddle-surfing one.
So, bottom line: if you’ve got to get wet, mark down Tuesday the 18th of August for a glassy dawny. Otherwise, the board’s staying in the car.
Rusty.

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.
