Weather in December

The heat index in December is estimated at a torrid 39°C (102.2°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. 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. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
