Weather in December
Temperature
December's onset records an average high-temperature of a still moderately hot 27.6°C (81.7°F), a near match to November's 28.2°C (82.8°F). Nighttime readings during December register a minimal drop from daytime highs, averaging at a still moderately hot 26.5°C (79.7°F).Heat index
In December, the average heat index is calculated to be a hot 31°C (87.8°F). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
