Weather in June
Temperature
As Johnson welcomes June, the average high-temperature sees a modest rise, transitioning from a warm 84.6°F (29.2°C) in May to a hot 90.7°F (32.6°C). Johnson witnesses a consistent average low-temperature of 70.3°F (21.3°C) throughout June.Heat index
June's mean heat index is calculated to be an extremely hot 111.2°F (44°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant 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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
