The Lowdown

Alright, I’m looking at the charts for the next 16 days and honestly, it’s a pretty grim outlook for this stretch. The only break showing up on the finder is Harlyn, and the guidance rates it low for a reason. It’s a beginner-friendly, sheltered spot, but it’s inconsistent and often crowded. The water temp is sitting at 67°F - that’s a solid 5°F warmer than usual for this time of year, so you’ll be surfing in a shorty.

The first proper surfable energy doesn’t show up until the morning of Tuesday the 19th of August, with a 4ft swell from the WNW, but the wind is a moderate cross-shore, and the wave comment is "poor surf conditions." The combined energy is only 130 (moderate wave energy), but it’s not clean. That pretty much sets the tone for the whole first week. Through the 19th and 20th, the swell gets bigger, hitting 7ft by Wednesday afternoon and 8ft on Thursday morning, with combined energy climbing into the 300s and 600s, but the wind is fresh cross-shore or cross-onshore, making it a messy, lumpy, choppy deal. For a sheltered spot like Harlyn, any swell over 5ft is already pushing it for beginners, and over 8ft it’s expert-only, but with this wind, it’s honestly more interesting for kite surfing than paddle surfing.

There’s a real gap from the 21st through the 26th of August, where most days have tiny swell under 3ft and poor wind, just a few clean moments on the 26th with cross-offshore winds, but the swell is only 1.0ft to 1ft. Not worth paddling out for.

The best window in the whole forecast comes around the 31st of August. Monday morning, the 31st, we see a 7ft swell from the west, with a period of 8 seconds, combined energy of 545 (moderate wave energy), and a light onshore breeze. The wave comment is “marginal surf forecast or questionable tide conditions,” but it’s the closest thing to a standout. The 7ft is expert territory, and the period is short, so it’ll be a bit crumbly. Still, it’s the only day where the energy is high and the wind isn’t totally wrecking it. Monday afternoon drops to 5ft with a longer 9-second period, but the wind stays onshore.

Overall, it’s a tough 16 days. Most of the time, the surf is poor, and the few moments of energy are blown out. If you’re desperate, keep an eye on the 31st of August, but don’t expect magic.

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.
