Not every corner of the region was basking in sunshine yesterday.

A strip of the coast wore a cooling cloudy cloak of a 'sea fret'.

Resorts and rural beaches between Hunstanton and Clacton suffered the same fate, said forecaster Jim Bacon at Weatherquest.

The phenomenon, also called a 'haar', was common at this time of year.

It was caused by warm moist air cooling over the sea, and condensing into low cloud.

At Cromer visitors heading to the beach and seafront were greeted by the sight of the landmark pier disappearing into grey mist.

Mr Bacon said the fret would have been thicker in some places than in others, where the sun burned it away. It only reached up to half a mile inland, but extended several miles out to sea over the cooler waters.

Temperatures were several degrees down on inland, but still comfortably warm. 'It could be a welcome relief for some, and disappointing for others,' said Mr Bacon. If the wind was offshore it would have blown it out to sea, but while it remain onshore the condition persisted - and today it was likely to go deeper inland he warned including to the Latitude festival.

But Sunday and Monday should see a return to sunshine for all.
