Weather in June
Temperature
Observing a minor shift, the average high-temperature during June adjusts from May's pleasant 73°F (22.8°C) to a moderately hot 81.1°F (27.3°C). During the June nights, an average temperature of 64.9°F (18.3°C) is observed.Heat index
For June, the heat index is computed to be a tropical 86°F (30°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Heat index details are generally centered around shaded locations and a mild breeze. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
