Temperature

The unfolding of January shows an average high-temperature of a still tropical 30.5°C (86.9°F), indicating a slight variance from December's 30.3°C (86.5°F). January's nights observe an average temperature of 22.5°C (72.5°F).

Heat index

The heat index value during January is appraised at a blisteringly hot 40°C (104°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
