Weather in April
Temperature
With the onset of April, the average high-temperature subtly transitions from a warm 75.6°F (24.2°C) in March to a still moderately hot 81.5°F (27.5°C). An average low-temperature of 63.9°F (17.7°C) is common in Markham during the nights of April.Heat index
April's heat index is estimated at a tropical 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
