Weather in March
Temperature
In March, the average high-temperature registers at a hot 30.4°C (86.7°F), nearly identical to February's 29.5°C (85.1°F). Throughout March, the temperature in L'Observatoire, French Guiana, tends to fall to a consistent average low of 21.3°C (70.3°F).Heat index
For most parts of March, the heat index is estimated at a blistering 41°C (105.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
Humidity
In March, the average relative humidity is 85%.Rainfall
In L'Observatoire, in March, during 26.5 rainfall days, 70mm (2.76") of precipitation is typically accumulated. Throughout the year, in L'Observatoire, there are 259.3 rainfall days, and 898mm (35.35") of precipitation is accumulated.Daylight

Sunshine
In March, the average sunshine is 5h.UV index
In March, the average daily maximum UV index in L'Observatoire is 6. A UV Index estimate of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for ordinary individuals.Note: The daily maximum UV index of 6 in March interprets into the following advice:
Prevent overexposure. Protection from the sun's harmful effects is needed. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
