The Lowdown
Alright, let’s size this up in feet and miles per hour. It’s a grim picture for Portreath Beach over the next 16 days, so don’t hold your breath.
The first wave worth talking about is on Monday afternoon, August 3rd. We’ve got a tiny 3ft swell from the WSW with a short 8-second period, and the energy is weak. The wind is blowing cross-off from the SSW at 9 mph, so the surface will be clean. The water is 65°, which is a touch warmer than normal. It’s surfable, but it’s nothing special.
From Tuesday, August 4th, through to Sunday, August 9th, it’s a complete wipeout. The wind is onshore or cross-shore, choppy, and the swell is either too small or too messy. There’s no reason to even think about paddling out.
Then, from Monday, August 10th, all the way to Tuesday, August 18th, it’s the same story. The swell stays tiny, mostly under 3ft, with weak, short-period energy. The wind is a mix of cross-off (clean but tiny) or cross-on/onshore, making it lumpy and choppy. The combined swell energy stays in the low range.
The one standout day, if you can call it that, is Friday, August 14th. The afternoon brings a 5ft swell from the W with an 8-second period and moderate energy. The wind is cross-on from the W at 16 mph, so it’ll be choppy. It’s the biggest swell of the whole period, but the wind will mess it up. For experienced surfers only, it’s the best of a bad lot.
This is a long, dry stretch for the area. Forecasts can change, but right now, there’s not much to get excited about.

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.
