Weather in December
Temperature
Getambe witnesses the coldest weather in December, with temperatures averaging a high of 27.5°C (81.5°F) and a low of 19.5°C (67.1°F).Heat index
In December, the heat index is calculated to be a hot 31°C (87.8°F). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. 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 hold particular significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
