Temperature

January and December, with an average high-temperature of 30.1°C (86.2°F), are the warmest months.

Heat index

In December, the average heat index is appraised at a fiery hot 37°C (98.6°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Note: The UV index of 6 during December leads to these advisories:
Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
