The Lowdown
Right, let’s have a look at what’s coming up for Harlyn over the next couple of weeks. I’ll be straight with you – it’s a challenging outlook, with a lot of onshore or cross-offshore wind and messy conditions. The main break we’ve got to work with is Harlyn itself, a sheltered, beginner-friendly spot that is inconsistent.
Overall Pattern: The first half of the forecast period is a write-off for decent waves. There’s a lot of wind and poor surf quality. It’s not until the second week, specifically around the 7th of September, that we see a slight glimmer of something surfable for those who are patient.
Friday 28th August kicks off with rain showers and a strong cross-offshore wind from the WSW at 19 mph. The swell is tiny – just 1.0 ft from the WNW with a period of 9 seconds. The combined energy is weak at 21. The water temperature is 66°F, which is a touch warmer than normal for the time of year. It’s not worth your time.
Saturday 29th August sees a jump in swell size, but the wind is the problem. Morning brings a 5 ft SW swell (period 7 seconds) with a howling 25 mph offshore wind from the S. It’s clean but the wind is so strong (189 combined energy – moderate) that it’ll be hard to paddle into. By the afternoon, a 8 ft WSW swell arrives, but it’s accompanied by a near gale cross-shore wind from the W at 31 mph. That’s a massive 1194 combined energy (very strong) – it’s a total mess.
Sunday 30th August is a bit cleaner. Morning has a 5 ft WSW swell with a fresh 19 mph SSW offshore wind. It’s clean (366 combined energy – moderate), but still a lot of wind. Afternoon brings a risk of thunderstorms, a 7 ft WSW swell, and a cross-offshore wind from the SW at 19 mph (589 combined energy – moderate to strong). Not terrible, but not a standout.
Monday 31st August through Wednesday 2nd September is all cross-onshore and cross-shore wind with lumpy, choppy conditions. Swell sizes range from 10 ft down to 2 ft, but the wind direction and strength ruin it. For example, Monday morning has a 10 ft W swell with a fresh 19 mph cross-onshore – 1374 combined energy (very strong) but poor quality.
The best on offer is a waiting game. Monday 7th September morning is the only slightly hopeful window. There’s a 4 ft swell from the WNW with a period of just 5 seconds, which is very short period and not great for shape. The wind is light from the WSW at 6 mph, which is a cross-offshore breeze, making it clean. Combined energy is a weak 102. It’s surfable but very ordinary. Given the inconsistency of Harlyn, this is the best you’ll get within the entire 16-day window, but you’d be scoring some weak, wobbly waves.
After that, things deteriorate again with more cross-shore and onshore winds through to the end of the forecast period. Expect a lot of gaps with no real recommendation.
Signing off: It’s a rough run for Harlyn. Patience is the key. That Monday morning might give you a few, but don’t hold your breath.

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.
