The Lowdown
Right folks, Rusty here. Let’s get straight into it for the next couple of weeks.
Honestly, looking at the whole 16-day window, it’s a dire stretch for Portreath Beach. We’ve got nothing but poor conditions and tiny waves. There’s a gap of several days at the start here with no surf worth mentioning, and it doesn't really get any better.
On Monday the 4th of August, a southwest windswell creeps in around 4 ft, but the period is a weak 7 seconds and a strong 16 mph southwest breeze is creating a messy cross-chop. The combined energy is moderate at best (171). It’s not a pretty picture. Tuesday the 5th of August sees a similar story with a 6 ft swell from the west and that same onshore wind, making for poor conditions and a combined energy of 301 – moderate, but the quality is shot.
Thursday the 7th of August offers a glimmer, with a lighter offshore breeze from the NNW and a 2 ft west-northwest windswell. It’s only 5 seconds of period, so it’s weak, but the wind might keep the surface a bit cleaner. The combined energy is very low at 44. It’s a scrap, not a session.
Beyond that, it's just a relentless grind of messy, onshore wind and tiny, weak swells right through to the 17th of August. There’s nothing that stands out as a top pick. The water temp anomaly is not provided in the data for the first mentioned break, so I can't say much on that.
The whole outlook is a long, flat spell with onshore winds. This setup would probably be more interesting for a kite surfer than a regular paddler, especially on the 5th of August with that 16 mph west-northwest wind.
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.
