Temperature

Transitioning from March to April, Sania observes an average high-temperature of a still moderately hot 29.7°C (85.5°F), differing subtly from the previous month. Throughout the month of April, Sania witnesses an average low-temperature of 23.1°C (73.6°F).

Heat index

April's average heat index is calculated to be a fiery hot 38°C (100.4°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially crucial for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Humidity

In Sania, French Guiana, the average relative humidity in April is 83%.

UV index

The months with the lowest UV index are January through June and December, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for the average person.
Note: A daily high UV index of 6 in April leads to these guidelines:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
