Weather in January
Temperature
Apastepeque's shift into January sets the average high-temperature at a still hot 31.8°C (89.2°F), a figure that deviates only slightly from December's 31.1°C (88°F). An average low-temperature of 21°C (69.8°F) is observed during the January nights.Heat index
For most parts of January, the heat index is evaluated at a very hot 38°C (100.4°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
