Weather in January
Temperature
The advent of January denotes an average high-temperature of a tropical 30°C (86°F), subtly different from December's 29.6°C (85.3°F). Izalco in January anticipates an average nighttime temperature of 20.5°C (68.9°F).Heat index
In January, the average heat index is evaluated at a hot 34°C (93.2°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Heat index determinations are made taking into account the shade and light air movements. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. 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 hold particular significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
