In December, the average heat index is estimated at a life-threatening hot 46°C (114.8°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Know that the heat index computations account for shaded terrains and slight winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Humidity

In December, the average relative humidity is 72%.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
