The Lowdown
Hey, Rusty here again. Let’s break it down in the old measurements.
Honestly, it’s a quiet spell. From right now all the way through to about the 26th of July, there’s not a damned thing worth paddling for. Days of flat, tiny dribble, choppy onshore junk, or weak little waves that barely break. You’ll see a glassy morning here and there, but with swell heights stuck between 0.2ft and 0.8ft and periods as short as 5 or 6 seconds, it’s a total millpond. The combined swell energy is weak, sitting in the double digits – 84 or 50, sometimes as low as 14. That’s just a ripple on a pond. A long, boring wait.
The first little sign of life comes on the morning of Saturday the 25th of July. Harlyn gets a cross-shore swell from the WNW at 0.6ft (2ft), with a 12-second period, and the energy bumps to a moderate 121. The wind is light and cross-shore, so it’ll look clean, but it’s still tiny and weak. Nothing to get excited about.
Things start to change the following week. On the morning of Monday the 27th of July, Harlyn sees a 2.0m swell – that’s about 7ft – from the W, with an 8-second period. The combined energy jumps to a strong 520. The wind is a light cross-offshore from the WSW, so the wave faces will be clean. But that 8-second period is short, meaning it’s windswell with less shape and more bounce. At that size, beginners should sit it out; this is expert water.
The morning of Wednesday the 29th of July looks even bigger but also a bit wild. A 2.2m swell (roughly 7ft) from the W, still with that short 8-second period, pushing the combined energy to a very strong 650. A fresh cross-offshore wind from the SW will keep the faces clean, but that much water moving fast with such a short period makes for a heavy, chunky, and difficult wave. Only for the experienced crew, and even then, it’ll be a grunt.
So the bottom line? A long flat spell, then a few days of clean but short-period swell from the 27th to the 29th. The best of a bad lot is the morning of Monday the 27th at Harlyn – about 7ft from the W with light cross-offshore wind. That’s the one window that might be worth a look. The rest is a lot of nothing and a bit of messy power. Don’t plan a trip around it.
Rusty.

Information about the Harlyn Surf forecast
The above surf forecast table for Harlyn provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Harlyn can be found by selecting the local surf guide option on the grey menu. Our Harlyn 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 (Harlyn) 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 Harlyn 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.
Harlyn is 6 km (4 miles) from Padstow. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Padstow. Padstow has rooms for a wide range of budgets as well as car hire and transport links.
