Weather in April
Temperature
Stepping into April, Primero de Enero records an average high-temperature of a tropical 30.3°C (86.5°F), almost consistent with March. During the month of April, the temperature falls to an average of 22.3°C (72.1°F).Heat index
The heat index value for April is calculated to be a sweltering 36°C (96.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

The months with the highest UV index are March through October, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the average person.Note: The maximum daily UV index of 7 during April translates into the following directions:
Resist extreme sun exposure. Guarding against solar damage is essential. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
