The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
To be straight with you, this is a rough run for Portreath Beach. We’re lookin’ at a solid stretch of poor surf conditions with no real standouts. The forecast is a long, frustrating gap of junk. You’re better off waitin’ for the next swell window.
The first real shot at anything is on Wednesday the 12th of August. We’ve got a small, clean-looking morning with a 3ft swell from the west, period around 10 seconds, and a moderate ESE breeze keepin’ it cross-off. The water is a touch warmer than normal at 65°, about a degree and a half above average for this time of year. It’s rideable, but nothin’ to write home about. The afternoon stays similar, with a 3ft west swell, but the wind is light and cross-off, so it’ll be clean.
The energy picks up Thursday the 13th with a 4ft west swell and a period of 11 seconds, but the wind swings around to a NNW cross-on and then a NW onshore, and it’s just choppy and messy. No good.
From Friday the 14th through to Monday the 24th of August, it’s a relentless grind of onshore and cross-onshore winds, mostly from the north and northwest, keepin’ the surface lumpy, choppy, and blown out. Swell sizes bounce between 2ft and 4ft, but with periods all over the place and winds strong enough to ruin it, there’s not a single session worth paddling out for. The combined energy is weak to moderate at best, never breakin’ past 353 (moderate energy) and often sittin’ well under 100.
Late in the run, Monday the 24th of August, the wind goes howlin’ from the north at 25 mph, bringin’ a 7ft cross-onshore mess. That’s a strong breeze (564 combined energy), but it’s only for experts and even then, it’s junk. Tuesday the 25th and Wednesday the 26th show a bit more size, up to 8ft, but the wind is still onshore or cross-onshore. The afternoon of the 26th hits 8ft with a west-northwest wind, and the energy jumps to 730, but it’s a marginal forecast with questionable tide.
Honestly, for the whole 16-day window, there’s not a single day that stands out as a proper session. It’s a blank run, and for this area, when the wind locks in from the north and northwest, that’s just how it goes. You might get a clean-ish window on the 12th, but it’s tiny. Keep your eye on the charts, but for now, I’d be findin’ something else to do.
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.
Portreath Beach is 5 km (3 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
