Weather in May
Temperature
Markham marks the start of May with an average high-temperature of a still moderately hot 85.5°F (29.7°C), hinting at a slight fluctuation from April's 81.5°F (27.5°C). May is noted for a mean low-temperature of 69.1°F (20.6°C).Heat index
Throughout May, the heat index is estimated at a sweltering 95°F (35°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
