Weather in January
Temperature
The highest point of temperatures falls in January and February, when the average high-temperature ascends to 36°C (96.8°F).Heat index
The heat index for January is appraised at a life-threatening hot 45°C (113°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

The months with the highest UV index are January through April, October through December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for the average person.Note: The daily maximum UV index of 7 in January interprets into the following advice:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
