January weather forecast
Itamari, Brazil

January, the same as December, in Itamari, Brazil, is a hot summer month, with an average temperature varying between 30.2°C (86.4°F) and 19.5°C (67.1°F).

Temperature

January notes an average high-temperature of a still hot 30.2°C (86.4°F), subtly differing from December's 30.4°C (86.7°F). The temperature dips to an average of 19.5°C (67.1°F) during January nights.

Heat index

The heat index value during January is estimated at a sweltering 39°C (102.2°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Heat index evaluations are typically in the context of light winds and shaded environments. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Humidity

The average relative humidity in January is 82%.

UV index

Note: The UV index of 6 in January translates into these instructions:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
