Daily temperature extremes for Britain

Abstract

The utmost care has been taken in checking available records and conditions of therm-ometer exposure in order to provide tables of Britain’s extreme temperatures for every date of the year. The stages at which comparable standards of exposure (including site exposure) were implemented, following the invention of the Stevenson screen in 1866, have been dis-cussed by Webb and Meaden (1993) and Parker (1994). Table 1 lists Britain’s highest recorded temperatures for every date of the year. This covers the period beginning with the introduction of standardised thermometer exposure in the mid-1870s and ending on the last day of 1999. It fully updates the list pub-
