January weather forecast
Iguaraçu, Brazil

January, like December, in Iguaraçu, Brazil, is another warm summer month, with an average temperature varying between 20°C (68°F) and 28.8°C (83.8°F).

Temperature

Iguaraçu, Brazil, experiences a subtle adjustment in high-temperatures to a still moderately hot 28.8°C (83.8°F) with the onset of January, maintaining near parity with December's 29.5°C (85.1°F). Iguaraçu experiences a mean low-temperature of 20°C (68°F) during January.

Heat index

Throughout January, the heat index is computed to be a fiery hot 35°C (95°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. 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 extremely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

UV index

The months with the highest UV index in Iguaraçu are January through March, August through November, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for ordinary individuals.
Note: In January, the UV index of 6 transforms into the following advice:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
