The Lowdown
Alright, let’s break this down, folks.
Honestly, the next week and a half is looking pretty grim for decent waves. We’ve got a heap of onshore and cross-onshore wind messing everything up, and most of the time it’s just poor surf conditions. There’s a long dry spell in there where I wouldn’t bother suiting up. The water’s sitting a touch warmer than usual for this time of year, about 64°, but that doesn’t help the chop.
There’s a bit of size early on, but it’s ugly. Monday the 7th has a 8ft west swell rolling in, but with 12 mph onshore wind, it’s just blown out. The swell energy is strong at (1783), but with that wind, you can forget it.
The one real highlight, the one I’m getting stoked about, is Sunday the 20th. That morning, Portreath Beach should have a clean 6ft swell out of the WNW with a long 12-second period, and a light offshore breeze from the ESE. That’s going to be clean. The combined energy is solid at (905), and get this—by the afternoon it goes glassy. That’s your day. That’s the best bet on the board.
Before that, Friday the 18th has some clean 5ft swell with offshore wind, but the period is a bit shorter at 11 seconds, and the conditions are only marginal, so it’s not the same quality.
After that Sunday, Monday the 21st gets hammered by a strong cross-onshore wind, so that window shuts down quick.
Bottom line: hang tight through the garbage, and get your schedule clear for the 20th. That’s the one.

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.
