Weather in April
Temperature
April's average high-temperature stands at a still hot 30.3°C (86.5°F), showing little deviation from March's 30.7°C (87.3°F). In April, Buenos Aires reports a consistent average low-temperature of 25°C (77°F) during the nights.Heat index
For most parts of April, the heat index is estimated at a sweltering 38°C (100.4°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

The months with the highest UV index are January through October and December, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV rays for the ordinary person.Note: During April, 7 as the daily maximum UV index converts into the following advice:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. 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. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
