The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Portreath Beach over the next couple of weeks.
Right off the bat, I have to be honest with you – it's a rough start. The forecast is calling for a long, dry spell with hardly any surf worth paddling out for. We're looking at nothing but poor conditions right through the end of July and into the first week of August. The wind is mostly cross-onshore, the swell is tiny, and the energy is just not there. The combined wave energy barely gets into double digits most days, and when it does, it's still weak. You'll be sitting on your board doing nothing.
The first real glimmer of hope doesn't come until late in the run. On Monday the 27th of July, the swell starts to show a pulse. The combined energy climbs to 252 (moderate) and we see a 4ft swell from the WNW with a 9-second period. The wind is a gentle cross-shore, which is an improvement. It's still labelled as poor surf, but it's the best we've seen all week. The water temperature is a touch warmer than normal for this time of year, sitting at 64°F.
Then, there's a real standout, but you have to be patient. On Tuesday the 28th of July, the morning session offers something special. We get a light ESE wind, which is a clean cross-offshore breeze, and a 2ft swell from the west with a 9-second period. The energy is weak (43), but the wind is the key here – it will be glassy and clean. For a spot like Portreath Beach, that's a rare gift. The swell is small, perfect for a longboard or a funboard, and it's going to be a real treat for the soul. This is the best bet in the entire 16-day window – a clean, clean morning.
After that, the outlook gets messy again. The wind swings back onshore or cross-onshore, and the swell energy stays low. The second week of the forecast is a write-off, with small, choppy, and weak surf through to the 5th of August. The combined energy is mostly in the teens or twenties, which is barely enough to get you moving.
So, to sum it up: the first week is a total bust. The standout is the morning of Tuesday the 28th of July. If you're free, that's the one to chase. The rest of the run is a waiting game.
Rusty.

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.
