Weather in June
Temperature
As June begins, there's a slight increase in the average high-temperature, moving from a pleasant 73°F (22.8°C) in May to a warm 81.9°F (27.7°C). In the month of June, the temperature generally rests at an average low of 64.4°F (18°C).Heat index
The average heat index in June is calculated to be a hot 87.8°F (31°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
