The Lowdown

Alright folks, Rusty here. Let me level with you about the Cornish coast for the next couple of weeks. To be honest, it’s a bit of a rough stretch. The models are showing a whole lot of nothing for a good while, and when the swell does show up, the wind is going to be a pain in the backside. We’ve got a long wait ahead.

The first sniff of anything rideable isn't until the 26th of July, which is a Sunday. That’s a full week of flat, onshore junk before we even get a look-in. So, for the first week, don't bother checking the cams, you’ll only get sad.

Right, so let's start where we can. Portreath Beach is the only game in town mentioned, and it’s a tough one. This is a beach break, fairly exposed to the NW, and we need that NW swell to line up. The water temp is about average for the time of year, nothing unusual there.

The first real pulse of energy shows up on the afternoon of the 26th. We’re looking at a 4ft swell from the west, but with a period of just 6 seconds. That’s weak, short-period windswell, and the combined energy is only 119 (moderate). The real killer is the fresh cross-onshore wind from the WNW. It’s gonna be lumpy and choppy. Not a day for a classic ride.

We get a bit more oomph on the 27th. The morning sees moderate energy at 149, but the afternoon is where it gets interesting. Swell jumps to 5ft from the west, with a 9-second period, and the combined energy hits 332 (moderate). The wind goes light onshore from the NW. It’s still not clean, but there’s more push.

Now, the biggest swell of the whole window hits on the 28th of July. Tuesday morning has a 7ft swell from the north, with a short 7-second period. The energy is strong at 861 (moderate to strong). This is a big, chunky, messy beast. It’s also 7ft, so that’s getting into expert-only territory, especially with the moderate cross-onshore wind making it choppy. The afternoon drops to 7ft, and the wind goes light onshore, which is a slight improvement, but the period is still short and fat.

If I had to pick a standout, and I’m stretching here, it would be the afternoon of the 27th of July. The 5ft west swell with a touch more period and light onshore wind is the best combo of size and relative calm we get. It’s not going to be epic, but it’s the least ugly option in the lineup. The rest of the two weeks is a mix of weak dribble and onshore slop. There’s a spike in wind on the 31st of July with strong offshore winds from the ESE, but the swell is small and weak. That’s a kite day, not a paddle day.

Hang in there, lads. The forecasts can change, but right now, it’s a waiting game.

Rusty.

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.
