Weather in December
Temperature
December brings an average high-temperature of a still tropical 30.4°C (86.7°F), nearly identical to the preceding month. During the month of December, the temperature falls to an average of 25.3°C (77.5°F).Heat index
In December, the average heat index is appraised at a sweltering 39°C (102.2°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. 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 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
