Weather in April
Temperature
April is the warmest month, with the temperature often reaching an average high of 27.6°C (81.7°F) and an average low of 17.9°C (64.2°F).Heat index
In April, the average heat index is evaluated at a hot 32°C (89.6°F). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
