Weather in January
Temperature
With the advent of January, Indiana's high-temperatures adjust to a warm 29.3°C (84.7°F), closely aligning with the preceding month. An average low-temperature of 21.3°C (70.3°F) is common in Indiana during the nights of January.Heat index
The heat index in January is computed to be a fiery hot 36°C (96.8°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for average individuals.Note: In January, the average maximum UV index of 6 translates into the following recommendations:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
