Weather in January

January, like December, is another tropical summer month in Itatuba, Brazil, with an average temperature varying between 21.5°C (70.7°F) and 30.6°C (87.1°F).

Temperature

Itatuba's average high-temperature in January is a still tropical 30.6°C (87.1°F), marking an insignificant difference from the 30.7°C (87.3°F) of December. Itatuba usually reports an average low-temperature of 21.5°C (70.7°F) during the month of January.

Heat index

The heat index value during January is computed to be a very hot 37°C (98.6°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

UV index

January through June, August through December, with an average maximum UV index of 6, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the average person.
Note: A daily high UV index of 6 in January leads to these guidelines:
Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
