Weather in January
Temperature
With the transition into January, Gertrudsburg notes an average high-temperature of a still moderately hot 27.5°C (81.5°F), closely resembling December. During the nights in January, Gertrudsburg experiences a consistent average temperature of 17.6°C (63.7°F).Heat index
Throughout January, the heat index is calculated to be a hot 30°C (86°F). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Consider that heat index readings are for situations in the shade and light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
