The Lowdown
Alright, let’s talk surf in proper units. Rusty here, and the outlook for the next couple of weeks is a bit of a slow-burner. We’ve got a long stretch of nothing to start, so don’t be in a rush.
From the start through the first week, it’s pretty grim. The 6th and 7th are a total write-off with onshore winds making a mess of things. Monday the 7th sees a bit of a pulse with a 7ft swell from the west, but it’s a 13-second groundswell and the wind is choppy. That size is over 8ft, so it’s only for the experts, and with the wind, it’s a no-go. The whole week looks more like a kite-surfing setup than a paddle day.
The real standout, the one you’ve been waiting for, is Thursday the 17th. The afternoon session at Portreath Beach is where it’s at. We’ve got a 4ft swell from the west-northwest, and the wind goes glassy, an easterly at just 3 mph. It’s clean, it’s glassy, and the swell period is a solid 9 seconds, so it’ll be a fun wave. The water temp is a touch warmer than usual at 64°F. This is the best on offer.
Before that, there’s a few scraps. Thursday the 10th morning has a clean 4ft swell, but it’s a short 7-second period, so it’ll be weak. The 14th is glassy, but the swell is only 2ft – not worth it. The 17th is the one.
The second week is a slower one. The 18th and 19th have some clean offshore mornings, but the swell stays around 3ft. It’s surfable, but nothing special. The 20th is clean too, but small.
So, to sum it up: don’t bother until the 17th. That Thursday afternoon glass-off at Portreath is the only real highlight. The rest is just waiting.
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.
