Weather in June
Temperature
The transition from May to June brings a subtle temperature rise, with average high-temperatures increasing from a moderately hot 83.8°F (28.8°C) to a tropical 90.9°F (32.7°C). Jack's nighttime temperature in June falls to an average of 70.2°F (21.2°C).Heat index
For June, the heat index is calculated to be a blistering 111.2°F (44°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
