Weather in June
Temperature
The arrival of June brings an increase in high-temperatures, moving from 74.7°F (23.7°C) in May to a still moderately hot 84.6°F (29.2°C). Wentzville's temperature in June lowers to a consistent average of 65.8°F (18.8°C) during the nights.Heat index
The heat index value for June is calculated to be a fiery hot 95°F (35°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Heat index's context suggests values are appropriate for shady areas and slight breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
