Weather in June
Temperature
The start of June brings a subtle shift in the average high-temperature, edging up from May's moderately hot 83.3°F (28.5°C) to a tropical 90.7°F (32.6°C). Nighttime temperature dips to a mean of 69.4°F (20.8°C) during June.Heat index
June's mean heat index is computed to be a scorching 109.4°F (43°C). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly 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.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
