The Bognor Regis weather station pictured above, has been in Waterloo Square since 1897. Readings are taken every day of the year, and sent to the Met. Office. Measurements taken from the instruments inside include temperature, wind and rainfall.
Recording sunshine hours
The amount of sunshine hours are measured from a device called a Campbell-Stokes sunshine recorder which is located at Butlins. This device focuses light from the sun onto a piece of card where it leaves a burnt trace if the sun is bright enough. The more sunshine there is, the longer the burnt trace. The sphere acts like a magnifying glass and the card has to be specially treated so that it won't catch fire.
Pressure is measured by a barometer located at the Foreshore office on the promenade.
