The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’re looking at Harlyn for the next 16 days, and I’ll be honest with you – it’s a tough stretch. The water’s hanging around 64°F which is a touch warmer than usual for this time of year, but that’s about the only thing that’s looking good.

The forecast kicks off with a bit of swell on Friday afternoon the 4th, but it’s a messy 7ft cross-shore mess with a fresh breeze on it. The wave energy is moderate (641), but the conditions are just poor. Not worth paddling out.

Saturday the 5th is a little better. You’ve got a 5ft west swell with a nice 11-second period in the morning, and the wind is light, but it’s cross-onshore so it’s got small ripples. Still, the rating is low, and it’s only a marginal call. The swell drops to 4ft in the afternoon.

Sunday the 6th – the swell drops right off to 2ft, but the wind goes offshore in the afternoon. That’s clean, but the energy is weak (83). There’s some surfable waves but it’s very ordinary.

Now, Monday the 7th – that’s a big spike. A 8ft west swell with a 13-second period, and the energy is strong (1783). That’s a lot of power. But the wind is a moderate cross-shore, and the conditions are poor. That’s a choppy, lumpy mess. For experienced surfers only at that size, but the wind is just not cooperating.

The rest of the first week is a repeating pattern of moderate to fresh cross-shore winds, lumpy lines, and swell sizes jumping between 5ft and 7ft. The energy stays moderate to strong, but the wind is always ruining it. Tuesday the 8th has rain showers and 22 mph cross-shore wind. Wednesday the 9th is cross-shore again. Thursday the 10th has a clean cross-offshore wind, but the swell is dropping and the period is short (6-7 seconds), so the energy is weak (156-416). It’s just not coming together.

The second week, from the 11th onwards, is a slow fade. The swell drops to smaller and smaller sizes, and the wind is mostly cross or onshore, with a few brief clean windows. The 13th has a gentle offshore breeze and 2ft swell, but the energy is very weak (104). The 18th and 19th have glassy conditions, but the swell is tiny – 1ft and 0.3ft. The energy is below 50.

There are no standouts here. The best on offer is probably Saturday the 5th morning for a beginner session, or Sunday the 6th afternoon for a clean but small wave. But honestly, nothing is firing. The forecasts can change, so don’t write the whole period off, but as it stands, my advice is to wax the board and wait for a better window.

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.
