November weather forecast
Natuba, Brazil

The last month of the spring, November, is a tropical month in Natuba, Brazil, with an average temperature ranging between min 21.5°C (70.7°F) and max 30.3°C (86.5°F).

Temperature

The start of November sees the average high-temperature at a tropical 30.3°C (86.5°F), showing little difference from October's 29.4°C (84.9°F). November nights are marked by an average temperature drop to a pleasant 21.5°C (70.7°F).

Heat index

November's average heat index is estimated at a sweltering 37°C (98.6°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
