The Lowdown
Alright, let’s break down Portreath Beach for the next couple of weeks.
Honestly, the first week is a total bust. We’ve got a week of straight-up poor surf conditions from Thursday the 3rd through to Wednesday the 9th of September. The wind is a nightmare, mostly cross or onshore, and the swell is all over the place with a messy cross-chop. The water is 64°F, which is a touch warmer than normal for this time of year, but that’s little comfort when you’re battling a fresh breeze. There’s a bit of a pulse of energy on Monday the 7th with a 8ft swell from the west, but it’s a 13-second period groundswell that’s hitting the beach with a howling onshore wind (moderate wave energy, 1822). That’s a full-on expert situation, and even then, it’s going to be blown out. For a beach break, that’s looking more like a kite session.
There’s a gap of poor surf right through to the morning of Saturday the 12th, where we finally see a glimmer. Saturday morning (12th) has a 3ft swell from the west-northwest at 10 seconds with a light cross-shore breeze. The energy is moderate (413), but the wave comment is “marginal surf forecast or questionable tide conditions.” It’s only a 1 out of 10, so don’t get your hopes up. The afternoon is a bit better with a 5ft swell from the west-northwest at 11 seconds, and a clean cross-offshore wind. That’s the best of a very average week.
The standout, and I mean the only real highlight, is the morning of Tuesday the 15th of September. We get a 4ft swell from the west at 9 seconds, but the wind is glassy, dead calm. The wave comment says “expect good surf conditions,” and the energy is moderate (278). For a beach break, glassy conditions are gold. The swell isn’t massive, but it'll be clean and fun for an intermediate. A couple of days later, Wednesday the 16th also has glassy conditions in the morning and afternoon, but the swell drops to 3ft and 3ft, so it’s small and ordinary. Tuesday morning is the one to aim for, but remember, it’s a long way out, so keep an eye on the forecast.
After that, Thursday the 17th and Friday the 18th look to turn ugly again with onshore winds and lumpy, choppy conditions. A blank run like this is more normal for the area, but it tends not to stay poor for long, and forecasts can change.

A general guide to surfing at Portreath Beach can be found by selecting the local surf guide option on the grey menu.

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.
