Dona Augusta logs an average low-temperature of 26.6°C (79.9°F) during the nights of December, subtly lower than its daytime highs.Heat index
December's heat index is computed to be a hot 31°C (87.8°F). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. 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 highly critical for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
