The Weather

Weather stamps

Royal Mail celebrated one of the nation's obsessions on 13 March 2001 when it issued Weather stamps, which includes the first ever heat-sensitive stamp.

Rich in colour and beautifully illustrated

Rich in colour and beautifully illustrated, the stamps perfectly encapsulate the rich diversity and changeability of the Great Britain's weather.

Heat-sensitive stamp

And as quick as the weather changes, do does the colour of the cloud on the 27p stamp. A small section of the stamp has been printed with thermochromic ink which sees the cloud change from dark and gloomy to a cheerful sky blue when it is touched. Rubbing with a finger heats the paper and activates the ink, changing the colour.
