Alright, Rusty here, and I’ll be your eyes on the water for Portreath Beach over the next couple of weeks. Gotta be straight with you – we are staring down a long, dry spell. The first surf worth even looking at doesn’t show up until Monday, July 14th, and even then it’s a whisper. That’s over a week of flat or junky conditions before we get a pulse.

Alright, let’s walk through it.

The first bit of hope comes on Monday morning, July 14th. We’ve got a small 0.8ft swell pushing in from the west, with a period of 10 seconds – that’s a little groundswell energy, so the shape might have a bit of push despite the size. The wind is a light cross-shore from the NE at 9 mph, which leaves the surface a little choppy but not horrible. Combined energy is moderate at 177. It’s not great, but it’s the first window that’s not a total write-off.

Then, on Tuesday afternoon, July 15th, things get a little interesting. The swell drops to 0.7ft from the west, but the period stretches to 10 seconds and the wind goes glassy – ENE at 3 mph. That’s clean, no chop, just smooth lines. Combined energy is moderate at 126. The waves are small but the conditions are glassy, which is about as good as it gets for a wave that small. If you’ve got a log or a longboard, this is your session. The water temp is about 62°F, which is a touch warmer than normal for this time of year, so a spring suit should be fine.

Wednesday morning, July 16th, offers a similar story – 0.6ft from the west, 9-second period, but this time we get a gentle offshore breeze from the SE at 9 mph. That means clean, lined-up faces. Combined energy is moderate at 108. Again, small, but clean.

Beyond that, the second week gets a bit more active but messy. Sunday morning, July 20th, a pulse of 2ft from the WSW but with a short 6-second period and a cross-onshore wind. That’s a lumpy, weak windswell – not something to get excited about. And Monday morning, July 21st? A big 3ft groundswell from the west (10-second period) but hammered by a 25 mph onshore from the NW. Combined energy is through the roof at 2106, but that’s just a washing machine for experts only, and even then it’ll be a battle. Not a paddle-surf recommendation.

So, the standout window is Tuesday afternoon, July 15th, at Portreath Beach. Glassy conditions, a tiny but clean west swell, and the water’s a bit warmer than usual. It’s a longboarder’s dream. The next decent chance is Wednesday morning, July 16th, with offshore wind and clean little waves.

The crowd here can be an issue, especially when it’s clean and small, so expect company if you go.

To sum it up: we’ve got a big gap of nothing until mid-July, then a couple of clean, small days. After that, the swell gets bigger but the wind ruins it. If you’re hanging for a paddle, aim for the glassy afternoon on the 15th.

Rusty, signing off.

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.

Portreath Beach is 5 km (3 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
