The Lowdown
Alright, let’s talk about what’s on offer for the next couple of weeks here. It’s gonna be a real mixed bag, and honestly, for the most part, it’s looking pretty grim. The first week is a bit of a write-off unless you’re desperate for a paddle.
We’ve got a long stretch coming up from Thursday the 27th of August right through to the end of the month, and it’s mostly poor surf with some strong cross-shore winds. The wave energy is weak, with values as low as 20 for the combined energy of all swells directed here, but it does bump up. The water temp is about average for the time of year, so nothing to complain about there.
The first real standout, or at least the best of a bad bunch, comes on Wednesday the 2nd of September in the morning. Portreath Beach is looking like our only real chance for a clean session. The swell is tiny, just 3ft from the WSW, but the wind is absolutely glassy – dead calm. That’s rare gold for a beach break, and it means the surface will be like a mirror. The combined energy of all swells directed here is only 72, so it’s weak, but for a quiet, clean cruise on a longboard, this is your window. Keep in mind it’s a fairly consistent spot, but crowds are often here, so get out early.
The rest of the period is a battle. A few mornings, like the 30th of August and the 4th of September, have clean conditions but the swell is either too small or the wind picks up to ruin it. There’s a bit of a pulse of bigger swell on the 29th of August with 8ft to 12ft from the SW and WSW, but with strong breezes and messy conditions, it’s more of a kite-surfing show than a paddle session. The combined energy of all swells directed here hits 2009 on the Saturday afternoon, which is strong, but the wind is cross-onshore and messy.
Looking further out, the second week doesn’t offer much redemption. The 11th of September has a 8ft swell from the west with a 9-second period and moderate cross-shore chop, but it’s only marginal. The combined energy of all swells directed here is 1033, so there’s plenty of power, but the quality is just not there.
So, to sum it up: hold out for Wednesday the 2nd of September if you want a clean, glassy morning. The rest of the time, it’s a waiting game. Forecasts can change, so don’t write the whole window off, but right now, it’s slim pickings.

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.
