Weather in May
Temperature
May's arrival brings an average high-temperature of a still moderately hot 85.5°F (29.7°C), slightly deviating from April's 81.5°F (27.5°C). Markham experiences a nighttime temperature average of 69.1°F (20.6°C) during May.Heat index
The heat index in May is computed to be a sweltering 95°F (35°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
