Weather in January

As with any tropical climate, Maceió, Brazil, exhibits uniform temperatures throughout the year, with January temperatures hovering at 30.2°C (86.4°F). Relative to December, the humid conditions persist, rendering January fairly humid too. Looking to the skies, residents can expect an adequate duration of daylight interspersed with mostly sunny hours. Equally important is the UV index, a critical determinant in planning outdoor activities. January presents a slight uptick in rainfall, receiving a significant 78mm (3.07") of precipitation spread over ten days.

Temperature

Maceió's weather, upon January's arrival, documents an average high-temperature of a still hot 30.2°C (86.4°F), nearly identical to the prior month. Throughout January nights, Maceió registers an average low-temperature of 22.4°C (72.3°F).

Heat index

January's mean heat index is evaluated at a fiery hot 37°C (98.6°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Take all required precautions, as unprotected skin and eyes can burn in minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
