Temperature

December's onset sees an average high-temperature of a warm 29.7°C (85.5°F), exhibiting a slight fluctuation from the previous month. December in Mexico witnesses an average low-temperature hovering around a pleasant 22.1°C (71.8°F).

Heat index

The heat index value during December is evaluated at a torrid 37°C (98.6°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

The average relative humidity in December is 81%.

Rainfall

In Mexico, in December, it is raining for 15.2 days, with typically 65mm (2.56") of accumulated precipitation. Throughout the year, there are 225.8 rainfall days, and 1023mm (40.28") of precipitation is accumulated.

Note: In December, the average maximum UV index of 6 translates into the following recommendations:
Resist overexposure. Safeguarding from solar damage is indispensable. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
