Weather in January
Temperature
In January, Floraí experiences a barely noticeable shift in meteorological conditions, with average high-temperatures moving from 29.8°C (85.6°F) in December to a still warm 29.3°C (84.7°F). Floraí cools down to an average low-temperature of 20.8°C (69.4°F) throughout the month of January.Heat index
The heat index value for January is computed to be a fiery hot 37°C (98.6°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. 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. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

A UV Index of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for the ordinary person.Note: The UV index of 6 during January translates into the following guidance:
Shun overexposure. Protection from sun ravages is indispensable. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
