Weather in June
Temperature
With the transition into June, Riverdale experiences a subtle uplift in average high-temperatures, adjusting from a moderately hot 80.8°F (27.1°C) in May to a hot 88.2°F (31.2°C). Riverdale's temperature in June lowers to a consistent average of 68.2°F (20.1°C) during the nights.Heat index
The heat index in June is appraised at a sweltering 102.2°F (39°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
