Weather in January
Temperature
With the onset of January, Maricá's average high-temperature clocks in at a still moderately hot 28.5°C (83.3°F), showing a minor fluctuation from the previous month. During the month of January, Maricá identifies an average nighttime low-temperature of 23.6°C (74.5°F), slightly lower than its daytime counterpart.Heat index
January's heat index is calculated to be a hot 34°C (93.2°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
