Best coastal walks in Cornwall for storm watchers

Why Cornwall earns its storm-watching reputation

Cornwall takes the full force of the Atlantic. There is nothing between the north coast and Newfoundland except open ocean, which means a low-pressure system tracking in from the west arrives here with unspent energy. Add granite cliffs that rise 60 to 90 metres straight out of the water, a coast path that runs almost the entire perimeter, and a scattering of harbour towns built on the trade that same ocean brought in, and you have arguably the finest storm-watching coastline in Britain.

Winter is the season for it. Between October and March the swell builds, the light turns theatrical, and the crowds vanish. What follows is a guide to cliff paths where you can stand safely, watch the sea do something spectacular, and still be back in a warm harbour pub by teatime.

Before you set out: swell, wind and tide

Reading conditions is the difference between a thrilling walk and a genuine emergency. A few things worth checking before you pull your boots on:

• Wind direction. A north-westerly or westerly wind on the north coast gives the most dramatic onshore swell. On the south coast, look for a southerly or south-westerly.
• Swell period. A long-period swell of 14 seconds or more means groundswell generated by a distant storm. That is what produces the big, heavy sets at Porthleven and St Ives Bay.
• Tide. Walk the cliff path on a falling tide where you can. Avoid descending to coves or harbour walls when the tide is pushing in, and never walk a beach beneath active cliff falls.
• The shipping forecast. If it says "storm force" rather than "gale", keep to car parks with sea views and short, sheltered stretches of path.
• Tell someone your route. Signal is patchy on the north cliffs. A text with your start point, direction and expected finish time costs nothing.

North coast cliff paths for Atlantic swell

The north coast is where the drama lives. Between Padstow and St Ives, the coast path threads around headlands that jut west into the prevailing weather, and there are several places where you can watch spray climb higher than the cliffs themselves.

• Trevose Head. A short walk from the car park near Constantine Bay to the headland and its lighthouse. West-facing, exposed, and superb when a big swell meets the rocks below. Stay on the path; the final approach to the head is grassy and slippery.
• Bedruthan Steps. The viewpoint above the steps gives a long view south-west along a line of sea stacks. In a westerly gale the water between the stacks turns white from top to bottom. Do not descend the steps in wet, windy weather.
• St Agnes Head and Chapel Porth. Engine houses on the skyline, a shattered cliff line below, and a reliable spot for wave photography. Walk south from the head towards Wheal Coates for the classic view.
• Zennor Head and Pendeen Watch. A wilder, quieter stretch. The path from Zennor to Pendeen takes in high moorland, granite outcrops and a lighthouse that has been taking Atlantic hits for over a century.
• Godrevy and Hell's Mouth. North of Hayle, Hell's Mouth does exactly what its name promises in a north-westerly. The clifftop paths above Godrevy give a wide, safe vantage point over St Ives Bay.

South coast walks when the wind swings southerly

When the weather comes in from the south-west or south, the Lizard peninsula and the harbours around Mount's Bay take the brunt instead. The advantage here is shelter options: you are rarely more than a mile from a village.

• Porthleven. The grandstand of Cornish storm watching. From the high ground above the harbour you can watch waves break clean over the old institute building on the quay. View from the clifftop or the car park above the village, never from the harbour wall itself.
• Mullion Cove. A small granite harbour tucked between towering cliffs. The path above it gives a fine view of seas breaking against the outer breakwater.
• Kynance Cove and the Lizard. Serpentine rock, dark and jagged, with white water thrashing below. The cliff path between Kynance and the Lizard lighthouse is manageable in most weather.
• Rame Head. On the south-east edge of the county, this headland catches easterly gales that the rest of Cornwall barely notices, and the walk from the car park is short and straightforward.

Harbours, heritage and warming up afterwards

Cornwall's maritime story is written into its harbours, and a storm-watching walk is only improved by finishing in one. Charlestown, with its tall ships and Georgian dock walls, is a fine place to end a south-coast circuit. Padstow and Fowey offer narrow streets, chandlers and a strong sense of a working port that has adapted rather than faded. Mousehole and Newlyn, side by side on the south coast, still land fish most mornings, whatever the weather has been doing overnight.

In many of these towns you can find small heritage centres and museums covering pilchard fishing, lifeboats and the wrecks that litter this coast. Ducking into one after a bracing walk is a thoroughly Cornish way to spend an afternoon.

Kit, photography and staying safe on the edge

Storm photography rewards preparation. A weather-sealed camera, a microfiber cloth for salt spray, and a sturdy tripod set low to the ground will get you far. A shutter speed around 1/1000 second freezes spray into shards of ice; around 1/4 second it smears the sea into something almost painterly. The best light usually arrives just ahead of the front, or in the twenty minutes after it passes, when a rainbow sometimes snaps across the whole bay.

Wrap up properly: waterproof shell, warm mid-layer, hat, gloves and a spare pair of dry gloves in the bag. Wear boots with real grip, because wet granite and wet grass are both treacherous.

Above all, respect the edge. Stand well back from cliff tops, keep dogs on a short lead, and never turn your back on the sea for the sake of a photograph. Waves on this coast regularly run far higher than expected, and no image is worth the risk. Watch from a proper viewpoint, enjoy the roar of it, and let the Atlantic do the rest.
