The Lowdown
Alright folks, Rusty here. I’ve been staring at Portreath Beach for the next couple of weeks and, honestly, it’s a tough one. This spot is usually fairly consistent, but the forecast is a real letdown. There’s basically no good surf on offer in the entire 16-day window. A few days might have a tiny window of rideable waves, but nothing that’d get me rushing down the road.
Let’s start from the beginning. Monday 20th July – nothing doing. The morning has a tiny 2ft swell from the north with a short 5-second period, and only 35 units of energy (weak). Wind is cross-off from the ESE at 6 mph, but the wave comment says “poor surf conditions.” The afternoon is even worse – 1ft from the WNW, 11 seconds, but cross-on wind at 12 mph. That’s a no-go.
Tuesday 21st and Wednesday 22nd are similar: small swell around 3ft to 3.5ft, short period, and cross-on winds blowing 9-19 mph. The energy never gets above 94 (still weak). Conditions are described as “poor” – no chance of a decent wave.
Then we get a brief glimmer on Thursday 23rd July. The morning has a light ESE breeze at 6 mph, blowing offshore, and the swell is 3ft from the north, period 6 seconds, energy 78 (weak). The wave comment says “surfable waves but very ordinary conditions.” It’s a 1 out of 10 – not a total washout, but definitely not a standout. The afternoon goes back to poor with cross-on wind.
After that, it’s a long dry spell. Friday 24th sees tiny 1ft swell, then Saturday 25th gets a bit bigger (3.5ft) but with strong onshore winds from the WNW at 22 mph – that’s more of a kite session than a surf. Sunday 26th has the biggest swell of the whole period: 6.9ft from the west, period 7 seconds, and a whopping 483 units of energy (strong). But the wind is onshore from the NNW at 16-19 mph, and the wave comment is “poor surf conditions.” For a beach break, that much onshore wind would make it a mess – definitely not for beginners, and even experts would struggle. That setup looks more interesting for kite surfing than paddle surfing.
The rest of the week into early August is a repeat of small, wind-affected swell. Monday 27th to Thursday 30th has 2ft to 3.5ft, mostly cross-on or onshore winds, energy ranging from 107 to 183 (moderate at best). Friday 31st July has a 4.3ft swell from the west with 9-second period and 261 energy, but again cross-on wind. Saturday 1st August and Sunday 2nd stay poor with onshore breezes. The last few days, Monday 3rd and Tuesday 4th, are no better.
So, bottom line: if you’re desperate for a paddle, Thursday morning 23

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.
