Temperature

With the start of January, Kiriwan Eliya measures an average high-temperature of a still moderately hot 29.3°C (84.7°F), not significantly differing from December's 28.4°C (83.1°F). During January, Kiriwan Eliya experiences an average low-temperature of 18.8°C (65.8°F) at night.

Heat index

The heat index value during January is computed to be a fiery hot 36°C (96.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'feels like', arises from combining readings of air temperature and relative moisture content. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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 human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
