Weather in January
Temperature
The highest temperatures are recorded in January, with averages reaching a high of 30.3°C (86.5°F) and a low of 19.3°C (66.7°F).Heat index
For most parts of January, the heat index is computed to be a torrid 37°C (98.6°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

January through March, November and December, with an average maximum UV index of 6, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for ordinary individuals.Note: The daily maximum UV index of 6 in January interprets into the following advice:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
