Weather in January
Temperature
Temperatures reach their minimum during January and December, recording an average high-temperature of 29.9°C (85.8°F).Heat index
January's average heat index is appraised at a sweltering 38°C (100.4°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
