Weather in December

In Juru, December is the month with the lowest recorded average temperatures, measuring a high of 30.6°C (87.1°F) and a low of 23.4°C (74.1°F).Heat index
The heat index for December is estimated at a blisteringly hot 41°C (105.8°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
