Weather in June
Temperature
June's arrival signals a temperature shift, moving from a warm 77.5°F (25.3°C) in May to a tropical 87.8°F (31°C). During the month of June, the temperature falls to an average of 69.4°F (20.8°C).Heat index
The heat index value for June is calculated to be a torrid 102.2°F (39°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
