Weather in January
Temperature
January experiences an average high-temperature of a tropical 30.8°C (87.4°F), barely different from December's 29.9°C (85.8°F). An average low-temperature of 22.8°C (73°F) is anticipated throughout the nights during January.Heat index
The heat index value during January is estimated at a torrid 38°C (100.4°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
