The Condobolin ARAS hosts the Bureau of Meteorology weather station with records starting from 1954. Earlier records from the Post Office date back to 1914. The station is in the Central West of NSW at an elevation of 195m. Annual average rainfall is 424mm (1914-2006). The Station is situated adjacent to the Lachlan river, just above its floodplain.

Rainfall is non-seasonally distributed. However, high summer evaporation rates which average between 8-10mm per day from the start of November to the end of February mean much of the rain during the summer months is ineffective. Cool season rainfall (April-October) is most effective and is utilised for winter cereal growing as the main cropping period. The pastoral enterprises rely on naturalised medics (Medicago spp) and some native grasses which also grow in autumn and spring.

Temperatures range from 33.5^oC (average January maximum) with an average of more than 5 days annually above 40^oC, through to 2.7^oC (average July minimum) with an average 23 days below 0^oC.

There is a frost period extending from mid-May to mid-September when minimum temperatures can fall to -3°C and occasionally lower.
