April weather forecast
San José Villanueva, El Salvador

April paves the way for the wet season in San José Villanueva with a significant increase in rainfall to 45mm (1.77"). This steep rise in precipitation invariably leads to damp surroundings and frequent soggy conditions. Coupled with this change, the marginally increased cloud percentage of 27 reduces visibility, and the city witnesses slightly darker days. Despite these patterns, the days remain long and warm, balancing the effects of increased rainfall. The consistent UV index reminds residents to maintain the use of ample sun protection when outdoors.

Temperature

The shift into April in San José Villanueva uncovers an average high-temperature of a still hot 32.5°C (90.5°F), subtly different from the previous month. An average low-temperature of 22.8°C (73°F) marks the month of April.

Heat index

Throughout April, the heat index is estimated at a blistering 41°C (105.8°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Deter overexposure. Protecting against the sun's effects is essential. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
