Weather in January
Temperature

The average heat index in January is estimated at a fiery hot 37°C (98.6°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
