Weather in January
Temperature
With its high average temperature of 31.4°C (88.5°F) and a low of 24.1°C (75.4°F), January is regarded as the warmest month.Heat index
January's average heat index is calculated to be a fiery hot 38°C (100.4°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
