The Lowdown
Alright, let’s have a look at what’s cooking over the next couple of weeks. It’s a slow burner, to be honest, but there’s a couple of windows that might get the blood pumping.
For the first week, the pattern is pretty grim. We’ve got a long stretch of pretty poor conditions with weak, short-period windswell and a lot of onshore wind messing things up. The first few days are a write-off. Things get a little more interesting towards the end of the month, but it’s not until the evening of Friday the 31st of July that we finally see a blip of something worth looking at. The good news is, after that, the second week of August kicks off with some proper size.
Let’s talk about Portreath Beach. This spot is a fairly exposed, fairly consistent break that’s best for intermediates. The water temperature is about average for the time of year, nothing to worry about there.
The first real standout window is on Friday the 31st of July. The afternoon brings a new pulse of swell from the WSW, pushing 6ft, with a proper groundswell period of 11 seconds. The combined energy is strong at 846. There’s a gentle breeze, but the conditions are described as marginal, and the score is low. It’s a bit of a gamble, but it’s the first sign of life after a long, flat spell.
Now, the absolute standout of the whole forecast is Sunday, the 2nd of August. Sunday afternoon is the one. We’re looking at a powerful 12ft swell from the W, with a solid 11-second period. The combined energy is massive, hitting 2501. That is serious, heavy water. The wind is a moderate cross-onshore, which is a bit of a bummer, but the file notes the swell is predicted to be too big for this break. This is expert-only territory. If you’re not a seasoned charger, stay on the beach. For those who are, the raw power on offer is something else.
The rest of the second week is a mixed bag. After that big Sunday, the swell drops back but stays rideable through Monday and Tuesday, with waves around 7ft to 5ft, but the wind is still onshore, keeping it messy. Later in the week, it drops right off again, returning to small, weak conditions.
So, to sum it up: a long, quiet start, a brief moment of possibility on the 31st of July, and then one big, powerful Sunday on the 2nd of August for the brave. The rest is forgettable.

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.
