Weather in December
Temperature
Alvarez's weather shows a minor temperature rise with the arrival of December, moving from a warm 28.5°C (83.3°F) in November to a hot 31.7°C (89.1°F). Alvarez endures a clear shift from daytime heat to a mean low-temperature of 17.5°C (63.5°F) during December nights.Heat index
For most parts of December, the heat index is computed to be a torrid 35°C (95°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Consider that heat index readings are for situations in the shade and light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
