Weather in June
Temperature
A shift in the average high-temperature is noticeable in June, changing from a moderately hot 75.7°F (24.3°C) in May to a still warm 85.6°F (29.8°C). During June, the temperature tends to dip to an average of 64.9°F (18.3°C) at night.Heat index
For most parts of June, the heat index is appraised at a torrid 96.8°F (36°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
