Temperature

January commences with an average high-temperature of a sweltering 36.1°C (97°F), showing little deviation from December's 34.5°C (94.1°F). The month of January sees a significant daily temperature drop, recording an average low-temperature of 19.8°C (67.6°F).

Heat index

January's average heat index is calculated to be an extremely hot 41°C (105.8°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours.
