Weather in June
Temperature
The shift from May to June sees an increase in the average high-temperature, transitioning from a pleasant 72.7°F (22.6°C) to a moderately hot 83.1°F (28.4°C). Napoleon records an average low of 65.8°F (18.8°C) throughout the nights in June.Heat index
June's mean heat index is appraised at a hot 91.4°F (33°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
