The lowest temperatures are recorded in January, with averages reaching a high of 29.1°C (84.4°F) and a low of 22.5°C (72.5°F).

Heat index

During January, the heat index is computed to be a very hot 37°C (98.6°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

The most humid month is January, with an average relative humidity of 87%.

Note: A maximum high daily UV index of 6 during January translates into the following directions:
Resist overexposure. Safeguarding from solar damage is indispensable. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat. Stay cautious! Sand and water reflections increase UV radiation potency.
