The Lowdown
Alright, let’s have it. Rusty here with the lowdown for Portreath Beach.
Honestly, it’s a real slow start. You’ve got a blank run from now, Monday the 14th, through to Sunday the 20th – a full seven days of “poor surf conditions.” The swell is there, but the wind’s a total letdown. On the 15th and 16th we hit some moderate to strong wave energy (522 and 1003), but the onshore wind is too fresh, and it’s all chop. Even on the 18th we’re looking at strong energy past 1600, but the cross-onshore wind just wrecks it.
Things get better on Monday the 21st, but it’s marginal – a 1.0m west-northwest swell with light cross-shore breeze. The real star, the one to mark on your calendar, is Wednesday morning the 23rd. That’s the cleanest we’ll see: 1.2m from the west, a light cross-offshore wind, and clean conditions. It’s small, but it’s your best shot.
Then, jumping ahead, Sunday the 27th brings a massive 3.5m southwest swell with an 11-second period and monster combined energy over 3000 (very strong). The wind is light and clean. But that kind of size at Portreath Beach is for hardcore experts only – it’s a beast and not for everyone.
To sum it up: the first week is a dud. The 23rd is your clean, smaller session, and the 27th is the big dog for the brave. Stay patient.

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.
