Weather in December
Temperature
Neves marks the onset of December with an average high-temperature of a still warm 27.5°C (81.5°F), subtly divergent from November's 27.1°C (80.8°F). Nighttime, during December, brings an average low of 26.6°C (79.9°F), a modest reduction from the day's peak.Heat index
In December, the heat index is appraised at a hot 31°C (87.8°F). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
