Weather in December
Temperature
In Dandaragan, the average high-temperature in December slightly increases from a moderately hot 29.5°C (85.1°F) in November to a hot 32.5°C (90.5°F). From significant daily highs, Dandaragan's nights in December cool down to an average low-temperature of 18.1°C (64.6°F).Heat index
For most parts of December, the heat index is evaluated at a tropical 34°C (93.2°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
