Weather in December

Temperature

Heat index

December's heat index is computed to be a tropical 32°C (89.6°F). If one remains active during constant exposure, it might cause exhaustion and heat cramps.
Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.

Humidity

The months with the highest humidity are November and December, with an average relative humidity of 83%.

Limit direct exposure to the Sun during these hours. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck. Attention! UV radiation is ramped up when reflecting off sand and water surfaces.
