Weather in January
Temperature
The yearly lowest temperatures occur in January and May, averaging a high-temperature of 29.8°C (85.6°F).Heat index
During January, the heat index is computed to be a scorching 40°C (104°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

January through June, November and December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.Note: The UV index of 6 during January translates into the following guidance:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
