Weather in March
Temperature
The arrival of March denotes a barely perceptible change in the average high-temperatures to a still moderately hot 29.5°C (85.1°F) from February's 29.1°C (84.4°F). Montagne Sable reports an average nighttime low-temperature of 22.8°C (73°F) in March.Heat index
In March, the heat index is computed to be a sweltering 37°C (98.6°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial.
