April weather forecast
Bostok, French Guiana

April marks a key change in Bostok's weather pattern as marked by an increase in rainfall from 82mm (3.23") in previous month to 129mm (5.08") in April. As spring advances, subequatorial weather takes precedence with higher rainfall and the resulting relative humidity. However, the consistent wind speed and daylight hours provide some amount of equilibrium to the weather. The rise in rainfall redefines the weather trend for April, signifying a shift from the relatively dry early months.

Realize that the values for the heat index are set for shaded places and light winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

In April, the average relative humidity is 89%.
