The highest temperature recorded was 45.4°C in January 1995, and the lowest was -3.7°C in July 1984. The greatest rainfall recorded in a year was 1 111.0 mm in 1978, and the least was 338.6 mm in 1993. These and other climate statistics for Brigalow can be found at on the Australian Bureau of Meteorology website, http://www.bom.gov.au/climate/averages/tables/cw_035149_All.shtml.

Extremes of Nature: The area is subject to the impact of some cyclones. The database maintained by the Bureau of Meteorology shows that since 1906, 13 cyclones have tracked within 200 km of the confluence, one of which has passed within 50 km (TC Gertie in December 1995). 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 can also be a potential danger. Records show that the Brigalow Station experiences 34 days annually with temperatures 35°C or warmer. 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 notionally 681.
