The Lowdown

Right, folks, Rusty here. Let’s be straight with you – if you’ve got your heart set on a proper surf this fortnight, you’re looking at a long, flat wait. The first crack at anything even remotely rideable doesn’t show up until mid-July, and even then, it’s a real struggle. We’re talking about a solid week of nothing before we even get a whisper.

The first real chance we get is around Friday the 17th. Harlyn’s got a tiny pulse of swell rolling in from the NNW, pushing about 3 ft, but the period is a short, weak 5 seconds. That’s a super short-period, windswell with weak energy (43). The early morning might be your best bet with a clean, cross-offshore breeze from the WSW, but the surf quality is rated as poor. It’s not going to be pretty, but it’s the first thing we’ve seen. The water’s a touch warmer than normal at 64°, a notable anomaly for this time of year.

The rest of the second week and into the third week is a real grind. The swell stays tiny and messy, mostly under 3 ft, with onshore winds battering it. Monday the 20th and Tuesday the 21st see a few more pulses, but it’s the same story – poor surf conditions, short period, and choppy, onshore winds. There’s a brief moment on the morning of Wednesday the 22nd with a clean cross-offshore breeze, but the swell is only 1.0 ft. It’s just not enough.

Now, here’s where it gets interesting, but it’s a long way off. Toward the end of the month, around Tuesday the 28th of July, the energy picks up. A new swell from the west arrives, hitting 6 ft with a period of 7 seconds. The combined energy jumps to 312 (moderate). That’s a bigger, more powerful swell, but it’s still a short period and the wind is a messy cross-onshore, so expect choppy, lumpy conditions.

Then, on Wednesday the 29th of July, the real spike comes. We’re looking at a 7 ft west swell with a period of 9 seconds, and the energy reading is a massive 613 (strong). But here’s the thing – that’s a big swell for Harlyn. It’s over 5 ft, so it’s getting too big for beginners, and with a 7 ft face, it’s firmly in the expert zone. The morning has a light, onshore breeze, which might keep it clean enough, but the afternoon turns cross-onshore. This is a classic case of a big swell that’s tricky to handle. The west swell direction is a good match for the WNW optimum, so it’s a good angle, but the size and the short period mean it’s going to be a powerful, fast, and potentially closed-out wave at this beach break.

The standout – if you’re an experienced surfer and you can wait, Wednesday the 29th of July is the only serious offering. Big west swell (7 ft), strong energy (613), and the light morning wind could offer a brief window of cleaner waves. It’s a promise, but it’s a long way off and the conditions are still tricky. For the rest of us, this is a kite-surfing fortnight. The consistent onshore winds and small, choppy surf are much better suited to a kite than a paddle board.

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.
