The archives contain a history of storms, swelteringly hot days, devastating floods and more.
Here are 10 occasions when the city’s weather won't easily be forgotten.
1. Floods of the 1950s
Severe flooding struck Sheffield in July 1958 - the Sheaf Valley was badly hit and Broadfield Road was deluged to a depth of two feet. This picture shows Millhouses Park, and the remains of a bridge which spanned the river. Photo: Julia Armstrong
2. Ravaged by a hurricane
A gale affecting the eastern Pennines wreaked havoc in Sheffield on February 16, 1962, with wind speeds hitting 96mph. Trees were uprooted and over 100,000 buildings were damaged, while four people were killed and 6,000 left without homes.

3. Sizzling in a heatwave
A scorching heatwave led to what became - for nearly 25 years - Sheffield's hottest day ever on August 3, 1990. The mercury rose to some 34.3C, breaking the previous highest temperature for the city - 33.5C - recorded on August 9, 1911.

4. A phenomenon with staying power
This was another landmark event - in March 1994 a rainbow was observed above Sheffield for a full six hours, setting an official world record. The extraordinary arc of light was said to be seen continuously from 9am to 3pm, with observers at Sheffield University reporting its presence for much of the day. The Star's photograph, seen here, was taken in Sharrow. The city held its title for more than 20 years but was beaten by Taiwan's capital, Taipei, in 2017 when an unbroken rainbow was spotted there for nine hours. Photo: Picture Sheffield
