Weather in May
Temperature
Zwolle's transition into May is noticed by a slight rise in the average high-temperature, advancing from a moderately hot 77.4°F (25.2°C) in April to a still warm 85.3°F (29.6°C). May's average low-temperature reading settles at a refreshing 64.4°F (18°C).Heat index
The heat index in May is appraised at a torrid 95°F (35°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
