Aratuba experiences a recorded average high-temperature of a still tropical 30.6°C (87.1°F) in March, closely aligned with February's 31.1°C (88°F). In March, Aratuba's temperature tends to fall to an average low of 21.6°C (70.9°F) during the night.

Heat index

March's average heat index is computed to be a scorching 40°C (104°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. 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 calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Humidity

The average relative humidity in March is 82%.

Rainfall

The month with the most rainfall is March, when the rain falls for 26.8 days and typically aggregates up to 158mm (6.22") of precipitation.

Daylight

In March, the average length of the day is 12h and 8min.
On the first day of March, sunrise is at 05:42 and sunset at 17:54. On the last day of the month, sunrise is at 05:38 and sunset at 17:42 -03.

Sunshine

The month with the least sunshine is March, with an average of 5.9h of sunshine.

UV index

January through July, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for average individuals.
Note: The UV index of 6 in March translates into these instructions:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
