Temperature

January records an average high-temperature of a still moderately hot 29.3°C (84.7°F), indicating a minor variation from the preceding month. Madawala, during January, witnesses an average low-temperature of 18.8°C (65.8°F).

Heat index

The heat index value during January is computed to be a torrid 36°C (96.8°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
