Weather in January
Temperature
The shift from December to January is characterized by an average high-temperature of a moderately hot 29.8°C (85.6°F), not significantly different from the 30.1°C (86.2°F) of December. During January, the average low-temperature is 23.8°C (74.8°F).Heat index
The heat index value for January is evaluated at a tropical 33°C (91.4°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
