Temperature

Hiripitiya records a slight change with January's average high-temperatures adjusting to a still warm 29.3°C (84.7°F) from December's 28.6°C (83.5°F). Hiripitiya usually reports an average low-temperature of 19°C (66.2°F) during the month of January.

Heat index

In January, the heat index is computed to be a torrid 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
