Table - best surf conditions forecast for Portreath Beach over the next 16 days.
Alright, I tell you what, it’s a bit of a quiet start at Portreath Beach. We’ve got some swell on the way, but for the first week and a half, the conditions are just not cooperating. The wind is a real issue, mostly cross-off or cross-on, and it’s killing any chance of decent waves. The water temperature is 63°, which is a touch warmer than normal for this time of year, but that’s about the only nice thing going on.
We’re looking at a gap of over a week with no surf worth getting wet for. From July 12th right through to the 21st, it’s all poor surf conditions. The swell is small, mostly under 3 ft, and the period is short, around 5 to 7 seconds, so it’s weak and disorganised.
There is a glimmer, and I mean a glimmer, on July 22nd, which is a Wednesday. We get a big jump in swell, kicking up to 10 ft from the WNW, with a period of 8-9 seconds. The combined energy is very strong, hitting 1201 and then 1664. But look, it’s labeled as marginal, and those are big numbers for this beach, especially with onshore wind. At 10 ft, that’s expert territory only, too big for anyone else. The wind is onshore from the NW, so it’s going to be a wild, messy beast.
After that, the swell drops back down through the end of July. The wind stays onshore or cross-on, so it’s poor conditions all the way to the 27th. Honestly, if you’re a kiter, the setup on the 22nd might look interesting with the strong wind and big swell, but for a paddle surfer, there’s not a single standout session in this entire forecast. It’s a tough run, but that’s how it goes sometimes.

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.
