Weather in December

December, the first month of the summer in Salgado, is also a hot month, with an average temperature ranging between min 21.5°C (70.7°F) and max 31.8°C (89.2°F).

Temperature

Salgado experiences an average high-temperature of a still tropical 31.8°C (89.2°F) in December, subtly different from November's 31.5°C (88.7°F). Salgado records an average low of 21.5°C (70.7°F) throughout the nights in December.

Heat index

December's average heat index is evaluated at an extremely 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.
One should consider that heat index numbers are for shaded settings and light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Note: A maximum high daily UV index of 7 during December translates into the following directions:
Take precautions against overexposure. Protection against sun damage is needed. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
