Itaituba, Brazil

March, the first month of the autumn in Itaituba, is a tropical month, with an average temperature ranging between min 22.2°C (72°F) and max 30.3°C (86.5°F).

Temperature

March commences with an average high-temperature of a hot 30.3°C (86.5°F), showing little deviation from February's 29.9°C (85.8°F). Itaituba throughout March, experiences an average nighttime temperature of 22.2°C (72°F).

Heat index

The heat index value during March is appraised at a blistering 41°C (105.8°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

The average relative humidity in March is 88%.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. 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. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
