Roseworthy, South Australia

The Surveyor General of South Australia visited the site which would become Roseworthy on 13 December 1837. In 1855 land in the Hundred of Mudla Wirra was purchased by William and Grace Gartrell. In 1863 when William died Grace sub-divided the land and named it Roseworthy.^[4]

Roseworthy has a semi-arid influenced hot-summer mediterranean climate (Köppen: Csa/BSk) with warm to hot, dry summers and mild, slightly wet winters.^[5] On average, the town experiences 105.0 clear days and 122.3 cloudy days per annum. The wettest recorded day was 25 January 1941 with 112.5 mm (4.43 in) of rainfall.^[6] Extreme temperatures ranged from 48.3 °C (118.9 °F) on 24 January 2019 to −3.6 °C (25.5 °F) on 5 August 2020.^[7]

A newer weather station was opened in 1997. It records temperature, precipitation and 3 pm conditions.

The Kapunda railway line opened through Roseworthy on 13 August 1860 as an extension of the Gawler railway line. The line was later extended to the shipping port at Morgan. Another line was opened from Roseworthy towards Terowie on 14 December 1880 with the line being extended to Peterborough on 11 May 1881. All these lines were built 1,600 mm (5 ft 3 in) broad gauge with the exception of the Terowie to Peterborough section being 1067 mm (3 ft 6 in) narrow gauge. That line was converted to broad gauge on 12 January 1970. Regular Australian National passenger services ended in December 1986 but some special train tours ran through Roseworthy up until 2004. Grain trains last used the silos at Roseworthy on 2 February 2007, and the remaining stored hoppers were collected on 11 October 2007 marking the last use of the line.
