Weather in June
Temperature
The onset of June brings a minor temperature shift, with the average high-temperature moving from a moderately hot 75°F (23.9°C) in May to a still warm 82.6°F (28.1°C). Throughout June, the average low-temperature dips to an enjoyable 61.3°F (16.3°C).Heat index
The heat index value during June is calculated to be a tropical 89.6°F (32°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
