Temperature

A minor adjustment in Anajatuba's average high-temperature is noted with the start of January, touching a still tropical 30.8°C (87.4°F) from December's 32.4°C (90.3°F). Nighttime temperatures in Anajatuba consistently average an agreeable 22.7°C (72.9°F) during January.

Heat index

January's heat index is estimated at a blistering 42°C (107.6°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
