The highest temperature recorded was 44.9°C in January 1994, and the lowest was 2.0°C in June 2000. The greatest rainfall recorded in a year was 1 286.8 mm in 2000, and the least was 262.4 mm in 1993. These and other climate statistics for Charters Towers can be found at: Australian Bureau of Meteorology, http://www.bom.gov.au/climate/averages/tables/cw_034084_All.shtml.

Extremes of Nature: The area is subject to the impact of tropical cyclones. The database maintained by the Bureau of Meteorology shows that 25 cyclones have passed within 200 km of the confluence, however none have passed within 50 km. These cyclones bring with them potentially destructive winds and intense rainfall. Cyclone information for this area and all of Australia can be found at the Australian Bureau of Meteorology website, http://www.bom.gov.au/cgi-bin/silo/cyclones.cgi.

Extreme heat is also a danger. Records show that the Charters Towers Station experiences 60 days annually with temperatures 35°C or warmer, although temperatures rarely reach 40°C. Such extreme temperatures can cause heat stroke and death if appropriate measures are not taken such as avoiding strenuous physical effort, keeping as cool as possible and drinking lots of water. Heat waves kill more people in Australia than all other natural hazards combined.

Today: 

The total population of the degree square at the 2011 national Census was 455. The apparent significant increase in population at the 2011 census is probably due to changes in the census collection boundaries.
