The Lowdown
Alright, folks, Rusty here. Let's take a look at what's coming down the line for Harlyn. I gotta be straight with you – the next couple of weeks are a bit of a mixed bag. We got some waitin' to do before anything really gets good.
Right now, it’s a bit of a tough stretch. The water temp is currently about 64°, which is a touch warmer than normal for this time of year, so that’s a little treat.
The first real window of hope is around Tuesday the 22nd. Tuesday morning is lookin' pretty special. We got a clean 3.6ft west swell rollin' in, and the wind is totally glassy. That’s a recipe for pure, smooth waves out there. The combined energy is moderate (582), so there's some push behind it. This is the standout for the whole period – get on it early.
Tuesday afternoon sees the swell bump up to 4.3ft from the west-northwest, and the period jumps to a very long 16 seconds. That’s proper groundswell energy (1086 combined), but with that kind of period, it might be a bit straight for a beach break. Still, with a light north wind, it could be worth a look if the tide is right.
Then we get a good run on Wednesday the 23rd. The afternoon is the pick with a 3.9ft west-northwest swell and clean, cross-offshore winds from the east. The period is a solid 12 seconds, so the waves will have some shape and power (488 combined energy). That’s surfable and fun.
After that, it gets messy again. We get a few days of small, clean but weak surf from the 24th to the 25th, with energy levels dropping right down (82 to 63 combined). Nothin' to get excited about.
The last real promise comes on Saturday the 26th of September. The morning is showin' a 5.2ft west-northwest swell with a very long 14-second period. The wind is clean and cross-off from the southeast. The combined energy is strong (1024), so there's some grunt there. It won't be perfect, but it's the most solid bet in the second week for a surfer who knows what they're doin'. Keep an eye on that one.
For the beginners among us, anything over 5ft starts to get a bit spicy, and you'll wanna stick to the smaller, glassier windows early on.
So, overall: don't get too excited for the next week because it's mostly a write-off. The clear winner is Tuesday the 22nd morning for that glassy, clean swell. Wednesday the 23rd afternoon is a solid second option. The 26th holds some promise further out, but it's less certain. That’s the long and short of it.
Catch ya on the beach.

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.
