Heat index

Throughout January, the heat index is computed to be a very hot 37°C (98.6°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. 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 important for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

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

Note: The daily high UV index of 6 in January translates into this advice:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Be alert! The reflection of water and sand augments UV radiation intensity.
