Heat index

The heat index value during December is appraised at a sweltering 36°C (96.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', 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. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

In December, the average relative humidity is 59%.

UV index

Note: The daily high UV index of 6 in December translates into this advice:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. 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. Always opt for UVA and UVB-resistant sunglasses on radiant days.
