Weather in March
Temperature
The onset of March notes an average high-temperature of a still tropical 30.5°C (86.9°F), subtly shifted from February's 30.7°C (87.3°F). Barra experiences an average low-temperature of 22.4°C (72.3°F) in the month of March.Heat index
The heat index value during March is calculated to be a sweltering 37°C (98.6°F). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
