23°S 150°E Marlborough – Queensland by Degrees

IN THE DEGREE SQUARE Climate: The closest representative weather station is at the Rockhampton Aerodrome, which is located approximately 66 km south-east of the confluence, and has an elevation of 10 m. The station has been collecting data since 1939.

The greatest rainfall recorded in a year was 1 631.0 mm in 1973, and the least was 360.0 mm in 2002. These and other climate statistics for Rockhampton can be found at on the Australian Bureau of Meteorology website, http://www.bom.gov.au/climate/averages/tables/cw_039083_All.shtml. Extremes of Nature: The area is very much subject to the impact of cyclones. The database maintained by the Bureau of Meteorology shows that since 1906, 37 cyclones have tracked within 200 km of the confluence, yet only two of these passed within 50 km (two unnamed TCs in January 1943, and March 1949). 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.   Cyclone tracks within 200 km of point 1906 to 2006 (Bureau of Meteorology web site) Extreme heat is rarely a danger. Records show that the Rockhampton Station experiences only 18 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.
