Temperature

The commencement of December brings an average high-temperature of a still hot 32.5°C (90.5°F), marking an inconsequential divergence from November. Malappuram witnesses a consistent, sharp contrast from the daytime highs, with an average low-temperature of 20.4°C (68.7°F) throughout December.

Heat index

For most parts of December, the heat index is computed to be a blisteringly hot 42°C (107.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Humidity

The average relative humidity in December is 71%.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
