Weather in January
Temperature
December's transformation into January witnesses an average high-temperature of a still hot 30.2°C (86.4°F), noting a minor change from the preceding month. In January, the average low-temperature is a warm 24.1°C (75.4°F).Heat index
The heat index value for January is calculated to be a sweltering 37°C (98.6°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
