Design drybulb changes 1.7 °C per century (linear regression R² 0.18) ~> 37.7 °C mid century. 20.7 ° Design WB = mean of 10th highest 3PM each year + (std dev * 2.07) => this Design WB was exceeded 9.5 days/year (incl std dev 4.0 days/year). 20.9 ° alternative Design WB = mean of 10th highest daily maximum each year + (1 std dev) => alternative Design WB was exceeded 9.0 days/year (incl std dev 3.8 days/year).

Nighttime cooling rate 0.351 °/hr (average of all data). Diurnal pattern of days with 3PM DB ~ Design DB ~ Min at 03:42 ~ Max at 15:36 Nighttime cooling rate 0.596 °/hr from 19:53 to 06:56 (evenings following 3PM design conditions).
