Alright folks, Rusty here. Let’s be straight with you – this is a tough watch for the next couple of weeks. We’ve got a long, quiet stretch ahead, so don’t be holding your breath for any fireworks.

The overall pattern shows a real lack of energy. We start off with a few small, weak pulses that just don’t have the quality to get excited about. The water temp is sitting about average for the time of year, nothing weird there, just normal summer stuff.

From Wednesday the 8th right through to the end of the second week, it’s a pretty grim run. There’s a small window on Friday morning the 10th at Portreath Beach where we see a clean little 3ft wave from the west, with a period of 9 seconds. The wind is light and cross-off, which will keep the surface tidy, but the combined energy is only 139 (moderate). It’s surfable but it’s very ordinary – think long, slow walls with barely enough push. After that, it drops off a cliff. We’ve got a huge gap from Saturday the 11th all the way through to Wednesday the 23rd of July where the scores are dead zero. The waves that do pop up are either tiny, blown out, or coming from the north with a weak, short period that just won’t hold a face.

The one standout that finally appears is on Thursday morning the 23rd of July. Now, this is a long way out, so treat it with some caution, but the models are hinting at a pulse of swell. We’re looking at a 7ft wave from the north, but here’s the catch – the period is only 6 seconds. That’s short-period wind swell, so it’ll be bumpy and a bit chaotic. The combined energy jumps to 406 (strong), which is the only real power in the whole forecast, but the quality? The file says it’s marginal. That size (7ft) is getting into expert-only territory at a beach break like Portreath, especially with that short period. The wind is cross-off and moderate, so the surface might be clean, but the wave shape will be fat and closey. It’s a proper long-range maybe, not a guarantee.

The rest of the 16 days are a write-off. If you’re a kite surfer, you might find some interest in the stronger winds on the 14th and 15th, but for a paddle surfer, this is a blank run. It’s one of those periods where the forecasts can change, so keep an eye on it, but right now, I’d say pick up a longboard or find another hobby for a bit.

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.
