Weather in January
Temperature
The transition into January notes an average high-temperature of a still hot 30.3°C (86.5°F), revealing a mild distinction from the 30.4°C (86.7°F) in December. Caucaia's January nights experience a subtle temperature dip to an average of 25.3°C (77.5°F).Heat index
For January, the heat index is evaluated at a torrid 37°C (98.6°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
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. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
