March weather forecast
Certitude, French Guiana

March, the first month of the spring in Certitude, is a tropical month, with an average temperature varying between 30.1°C (86.2°F) and 21°C (69.8°F).

Temperature

The shift from February to March is characterized by an average high-temperature of a hot 30.1°C (86.2°F), not significantly different from the 29.3°C (84.7°F) of February. In the month of March, Certitude witnesses a consistent average low-temperature of 21°C (69.8°F).

Heat index

Throughout March, the heat index is estimated at a blistering 40°C (104°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

The average relative humidity in March is 86%.
