Weather in July
Temperature
In Lyon, July is the month with the highest recorded average temperatures, measuring a high of 89.6°F (32°C) and a low of 73°F (22.8°C).Heat index
In July, the average heat index is appraised at a blisteringly hot 107.6°F (42°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
