Weather in June
Temperature
The beginning of June signals a minor rise in the average high-temperature, moving from 75.4°F (24.1°C) in May to a still warm 84°F (28.9°C). Affton encounters a steady low-temperature average of 66.7°F (19.3°C) throughout the month of June.Heat index
June's mean heat index is evaluated at a tropical 93.2°F (34°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
