The Lowdown

Alright, let’s call it like it is: Harlyn’s got a grim outlook for the next couple weeks. Most days are just flat or blown out, so don’t get your hopes up.

Water temp is around 65°F, which is a touch warmer than normal. That’s about it for good news.

The first tiny chance is Tuesday afternoon, August 25th. We get glassy conditions with a 2ft swell from the west, period around 10 seconds. Combined energy is weak (96). It’s clean, but super ordinary. Only worth it if you’re learning.

The first real standout comes Thursday afternoon, August 27th. Glassy wind, clean, with a 3ft swell from the southwest, period 8 seconds. Combined energy is moderate (103). This is the best of the early run—clean and small. Expect crowds, it’s often busy here.

From Friday the 28th, things turn ugly. Swell builds but winds go bad. Friday morning sees a 5ft west swell with a 7-second period, combined energy moderate (205), but still ordinary.

There’s a long gap of poor conditions from the 29th through early September. Strong winds, rain, and storms. On Wednesday September 2nd, we get a 8ft to 8ft west swell with strong cross-off winds and combined energy in the high hundreds (783 to 870), but the wind is howling.

Next possible window is Saturday morning September 5th: a 8ft west swell with a longer period of 10 seconds, combined energy strong at 1513. But it’s cross-onshore and only marginal. For experts only.

Sunday morning September 6th brings a 7ft west swell with a 10-second period, combined energy strong at 873, and offshore wind from the SSE. Clean conditions, but still marginal. Might be better for kite surfing than paddling.

The final hope is Tuesday September 8th. That morning we get a 10ft west swell with a 13-second period, combined energy very strong at 3214. Wind is cross-off and light, clean. That’s a big groundswell with a long period, which is usually better at a point or reef. Harlyn is a beach break, so the waves could be too straight. That afternoon it drops to 8ft with a 12-second period, still cross-off, and conditions are rated very good. Combined energy still strong at 1575. This is the best looking surf in the whole forecast, but it’s over a week away (September 8th)—promising but not a lock. Only for experts.

So, if you want the cleanest small waves, go for the 27th of August. The 8th of September could be a big clean day, but it’s far out. For Harlyn, this kind of quiet spell is pretty normal.

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.
