The Lowdown
Hey, Rusty here again. For my imperial‑minded mates, same story for Portreast Beach – no good surf in the 16‑day window. From Saturday July 18th through Sunday August 2nd, every session is rated poor.
The water’s a touch warmer than normal at about 64°F. The only real pulse of energy hits on Saturday July 25th – combined swell energy of 411 (moderate) with waves around 6–7 ft from the WNW. But onshore NNW winds at 15–16 mph ruin it – messy and choppy. Before that, tiny swells with short periods and cross‑onshore breezes.
After that, it fades fast: weak 1–2 ft slop with a few longer‑period pulses early August, but still not clean enough. Even a 13‑second swell on July 24th is only 0.3 ft – nothing.
The cleanest looks are Monday July 20th morning (light cross‑offshore wind, 2 ft) and Sunday July 19th morning (offshore wind, 3 ft). Still tiny and weak.
A spot like Portreath usually gets more love than this. Don’t write it off forever – forecasts can change – but for now, save your energy.
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.
