June witnesses a minor rise in the average high-temperature, transitioning from a warm 73.9°F (23.3°C) in May to a still moderately hot 82.8°F (28.2°C). Dow experiences a steady low-temperature of 65.7°F (18.7°C) throughout June.Heat index
The heat index value for June is calculated to be a hot 89.6°F (32°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Observations indicate that the heat index values are for shady locations with light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
