April weather forecast
Mana, French Guiana

While the temperature peaks slightly higher at 29.7°C (85.5°F) in April, the overall weather in Mana significantly mirrors its March counterpart. A slight uptick in cloud cover percentage at 59% subtly shades the city under a semi-clouded sky. The smell of the sea may be purer as slight changes in wind speed are felt this month. It's worth noting that April signifies the end of the first quarter of the year without noticeable weather irregularities. Emerging into May, the city experiences a gradual change in its climatic rhythm.

Temperature

Mana's weather, upon April's arrival, documents an average high-temperature of a still warm 29.7°C (85.5°F), nearly identical to the prior month. In the month of April, the average low-temperature usually rests at a still moderately hot 23.1°C (73.6°F).

Heat index

The heat index for April is evaluated at a sweltering 38°C (100.4°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Note: In April, the UV index of 6 transforms into the following advice:
Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Stay cautious! Sand and water reflections increase UV radiation potency.
