April weather forecast
Nejapa, El Salvador

April brings significant changes in Nejapa's weather pattern, with a distinct increase in rainfall from 5mm (0.2") in March to a substantial 45mm (1.77"). This transition period from dry to rainy season comes with noticeable dips in sunshine hours. However, the increase in cloud cover does not significantly affect the daylight hours that stay around 12.5 hours per day. While breezy conditions are lost due to a drop in wind speed, UV levels remain constant. Despite the rain, April's weather oscillates from encouraging outdoor pursuits to cozy indoor activities.

Temperature

April registers an average high-temperature of a still hot 32.5°C (90.5°F), slightly varied from March's 32.6°C (90.7°F). Throughout April, a steady low-temperature average of 22.8°C (73°F) is noted.

Heat index

The average heat index in April is estimated at a blistering 41°C (105.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Note that heat index values are valued for light wind and location in the shade. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Humidity

The average relative humidity in April is 67%.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
