Weather in December
Temperature
December's advent notes a subtle adjustment in average high-temperature to a still moderately hot 28.9°C (84°F) from November. In December, Trentham Park encounters an average low-temperature of 21.5°C (70.7°F) during the night.Heat index
The average heat index in December is estimated at a fiery hot 35°C (95°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

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. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
