Weather in December
Temperature
With the onset of December, Herschel's average high-temperature clocks in at a still warm 28.2°C (82.8°F), showing a minor fluctuation from the previous month. Herschel records a consistent low-temperature average of 14.7°C (58.5°F) during December, indicating a significant difference from the daytime heat.Heat index
In December, the heat index is estimated at 28°C (82.4°F). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Humidity
In Herschel, the average relative humidity in December is 47%.Rainfall
The month with the most rainfall in Herschel is December, when the rain falls for 10 days and typically aggregates up to 43mm (1.69") of precipitation.Snowfall

Sunshine
The months with the most sunshine are January, October through December, with an average of 11.9h of sunshine.UV index
January, February, November and December, with an average maximum UV index of 6, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for the ordinary person.Note: The daily high UV index of 6 in December translates into this advice:
Deflect overexposure. Sun protection is a necessity. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
