Weather in June
Temperature
As Rock Island enters June, the average high-temperature marginally increases from the a warm 84.4°F (29.1°C) of May to a hot 90°F (32.2°C). An average nighttime temperature of 72.7°F (22.6°C) is noted during the month of June.Heat index
During June, the heat index is estimated at a scorching 111.2°F (44°C). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Understanding the heat index involves considering values for shaded locales with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
