The number of hot days where the maximum temperature reached or exceeded 36 °C in the cotton-growing season at Wee Waa, NSW (15 km west of the Australian Cotton Research Institute, ACRI). Data is between 1960 and 2019 and from Oct. 15 to Apr. 15, representing the duration of the modern Australian cotton industry. Despite the substantial year-to-year variation, the regression line shows a > 4 d increase in the number of hot days for a 10-year period. Horizontal lines represent the decadal average number of heat shock days.
