Weather in January
Temperature
The beginning of January records an average high-temperature of a still moderately hot 28°C (82.4°F), marking a negligible difference from December's 27.5°C (81.5°F). Santa Luzia, in January, logs an average low-temperature of 27°C (80.6°F), a subtle step down from daytime readings.Heat index
In January, the heat index is computed to be a tropical 32°C (89.6°F). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. A direct sunlight exposure may boost the heat index 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. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
