April weather forecast
El Salvador, Cuba

April, like March, in El Salvador, Cuba, is a moderately hot spring month, with an average temperature fluctuating between 21.4°C (70.5°F) and 29.6°C (85.3°F).

Temperature

The advent of April denotes an average high-temperature of a still moderately hot 29.6°C (85.3°F), subtly different from March's 28.4°C (83.1°F). During April, El Salvador witnesses a consistent average low-temperature of 21.4°C (70.5°F).

Heat index

April's mean heat index is calculated to be a torrid 35°C (95°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

In El Salvador, the average relative humidity in April is 76%.

Note: A daily high UV index of 7 in April leads to these guidelines:
Guard against overexposure. Protection from sun-induced harm is essential. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
