Weather in December
Temperature
With December's arrival, Akkaraipattu's weather records an average high-temperature of a still warm 28°C (82.4°F), marking little difference from November's 29.3°C (84.7°F). Akkaraipattu reports an average low-temperature of 24.5°C (76.1°F) during the subtly cooler December nights.Heat index
In December, the heat index is estimated at a tropical 32°C (89.6°F). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.

A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for ordinary individuals.Note: In December, a daily maximum UV index of 6 leads to the following instructions:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
