March weather forecast
Maceió, Brazil

In March, the weather in Maceió remains seemingly constant with little change in temperature; however, the real story unfolds with the rainfall. The city experiences a significant leap in the volume of precipitation at an impressive 195mm (7.68"). As the skies darken more often, residents find themselves indoors even more due to the rainy days. Concurrently, the daylight and sunshine hours decrease, aligning with the increased cloud cover. Despite this, the UV index stays at its peak, ensuring ample sunlight.

Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Enforce every key safety measure. Those with light skin might get burns in a matter of minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Even when it's cloudy, ensure the generous application and frequent reapplication of a sunscreen with at least 30 SPF, particularly post swim or outdoor activity. Warning! The Sun's UV rays intensify with reflections from sand and water.
