A broad sandy beach on Alderney’s north coast and the island’s best-known surfing bay when conditions are suitable. It is also used for swimming, particularly around low tide in calm weather, while falling water exposes rocks and pools that may provide a temporary connection to neighbouring Arch Bay.
These predictions use Braye Harbour, the Alderney reference location used by this service. Tide times and water levels at Corblets Bay may differ from the prediction because of the local shoreline, weather, waves and atmospheric pressure. Times are shown in local Alderney time.
Dogs are not allowed on Corblets Beach at any time from 1 June to 15 September.
Corblets is a broad sandy bay on Alderney’s north coast. Its open setting gives it a different character from the more sheltered water around Braye Harbour and Longis Bay, and it is particularly affected by northerly winds.
Visit Alderney identifies Corblets as the island’s best bay for surfing when conditions are right. Surf depends on the combination of swell, wind and tide, and the beach can look completely different from one visit to another; conditions suitable for experienced surfers may be unsuitable for ordinary swimming or paddling.
Corblets is also promoted for swimming, and local swimmers recommend it around low tide in calm weather. There are no lifeguards on Alderney’s beaches, so assess conditions yourself, supervise children closely and do not enter water beyond your experience. Stay within the bay and do not swim beyond the headlands, where offshore currents around Alderney can be strong.
As the tide falls, a broader sandy beach and rocks and pools are exposed around the bay. Around low tide, the rocks may provide a temporary connection to Arch Bay. This is an uneven, slippery shoreline crossing rather than a maintained path, so leave ample time and use the land route whenever there is doubt. The rocks can be slippery when wet or covered with seaweed; replace any stones you lift and leave marine life where you find it.
Corblets is exposed to northerly winds, which can create rougher seas and breaking waves. During northerly weather, Longis may provide more sheltered swimming conditions.
The width of Corblets Beach and the amount of exposed rock change considerably through the tide. Around higher water, more of the lower beach is covered and the remaining sandy shore becomes narrower.
At lower tide, a much broader beach appears and rocks and pools are uncovered around its edges. Explore the rocks as the tide approaches low water, leaving ample time to return before the sea begins covering the lower shore.
Around low tide, exposed rocks may provide a temporary connection to Arch Bay. The crossing is uneven, slippery and entirely tide-dependent: do not wait for rising water to reach the route before returning, and use the land route whenever there is doubt.
Local swimmers recommend Corblets around low tide when the weather and sea are calm. Surf conditions depend on swell, wind and tide, however, and the tide table alone cannot identify a safe swimming or surfing window. Corblets is exposed to northerly winds and may develop breaking waves, and actual water levels can differ from the prediction because of atmospheric pressure, wind and waves.
