The Lowdown
Alright, let’s break down what’s happening at Penthievre for the next couple of weeks.
Honestly, it’s a slow start. From the 16th right on through to the morning of the 28th, there’s barely a ripple. You’re looking at tiny 0.7ft to 2ft slop with very weak energy (5 to 80) and a lot of choppy or cross-on wind. There’s a few clean, glassy moments on the 18th, 19th, and 22nd, but with no swell behind it, you’re just staring at a flat lake. It’s a long, quiet stretch.
Things finally kick into gear on the 28th of July. The afternoon brings a 6ft swell from the SW, but it’s only got a short 7 second period and strong cross-on winds (35 km/h), so it’s gonna be a lumpy, messy closeout. The combined energy is moderate (301), but it’s not really one for the surfboard.
The real highlight is the morning of the 29th of July. Wednesday morning we’ve got a clean 6ft swell from the WSW with a 9 second period, and the wind is a light NNE cross-off. The combined energy is a strong 463, and with glassy, clean conditions, this is your best bet. Solid, fun waves for anyone comfortable on a bigger board. The afternoon gets choppy again as the wind swings cross-on.
Thursday the 30th still has some decent leftover energy – 4ft from the west in the morning with a light NNE offshore breeze. Energy is still moderate at 241, and it’s clean. Worth a look.
Then on the 31st of July, Friday morning, another pulse of 5ft from the west, 8 second period, with a light NNW cross-off. Combined energy is strong again at 493, and the conditions look clean. That’s your second standout, though it’s a ways out so don’t set your watch by it yet.
Water temp is about average for the time of year, nothing to write home about.
So, it’s a flat first week and a half, then a couple of really promising mornings at the tail end. Focus your energy on the 29th and the 31st.

Information about the Penthievre Surf forecast
The above surf forecast table for Penthievre provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Penthievre can be found by selecting the local surf guide option on the grey menu. Our Penthievre 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 (Penthievre) 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 Penthievre 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.
