Historical weather observations made at the University of Reading, Berkshire, UK

Historical Reading, UK, weather

Today is: 19 August 2017

Shown below are historical weather observations from the University of Reading (Berkshire, UK) climatological station.

Note that the current site on the University's Whiteknights campus was established in 1968-1970; prior to then observations were made closer to the town centre on the London Road.

The London Road observation site was also known as University College - in 1892 University College, Reading was formed; it received its Royal Charter in 1926 then becoming the University of Reading.

The London Road site was typically 0.4degC warmer during the day and 0.6 degC warmer at night with about 12 fewer days of air frost and 32 fewer days of ground frost over the year. Rainfall averages were very similar although sunshine duration amounted to about 90 h less over the year at London Road - which was closer to the (industrial) town centre and in a less rural location. Soil temperatures at London Road were about 0.8 degC higher at a depth of 30 cm when compared to Whiteknights.

Note that in early years measurements were made using imperial units (eg. F, ins and miles) and these have been converted to metric as appropriate. Also, soil depths were measured at depths of 2, 4, 6, 8 and 12 ins and at depths of 2 and 4 feet; these are noted here as being made at depths of 5, 10, 15, 20 and 30 cm and at 2 and 4 feet - the former are almost exact equivalents of the modern-day depths while the latter pair were later superceded by measurements at 50 and 100 cm.
