Weather in December
Temperature
Colo starts December with an average high-temperature of a still tropical 31°C (87.8°F), a minor shift from November's 31.8°C (89.2°F). An average low-temperature of 24.7°C (76.5°F) is recorded during the nights in December.Heat index
For most parts of December, the heat index is computed to be a scorching 41°C (105.8°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

A UV Index value of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for average individuals.Note: In December, the UV index of 7 transforms into the following advice:
Ward off overexposure. Defence against solar harm is crucial. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
