Many people in this County Durham town woke to dramatic scenes over the weekend as they could barely see the end of their street.

People in Seaham were surrounded by sea fret two mornings in-a-row as mist rolled in from the North Sea and covered the seaside town.

On Saturday morning, beach-goers and visitors in Seaham described low visibility spanning the whole town.

It comes as similar scenes as far up as Whitley Bay in North Tyneside have been reported with much of the North East coast experiencing the phenomenon.

What is sea fret and why does it happen?

Coastal fog, or sea fret, is fog that occurs over coastal regions during the spring or summer.

The fog is most common over eastern coastal areas and usually occurs as a result of advection fog.

This forms when relatively warm, moist air passes over a cool surface.

In the UK, the most common occurrence of coastal fog is when warm air moves over the cool surface of the North Sea towards the east coast of the UK.

The Met Office say: “When this happens, the cold air just above the sea's surface cools the warm air above it until it can no longer hold its moisture.

“This forces the warm air to condense, forming tiny particles of water which forms the fog that we see.”

Coastal fog usually occurs in spring and summer months when conditions warm up but the sea remains relatively cold.

The Met Office adds: “The impact, location and movement of coastal fog depend upon a number of conditions, including wind strength, wind direction and land temperature.

“If, as is common along the UK's east coast, the winds blow in from the east, the fog will often rapidly cover the coast in a blanket of fog. 

“If the land temperature is warm, the fog can quickly dissipate as the parcel of air warms. However, if the land temperature is cooler, the fog can linger for a longer time.
