Weather in July
Temperature
July's weather records an average high-temperature of a still hot 93.2°F (34°C), showing little deviation from June. Rock Island records an average nighttime low-temperature of 74.7°F (23.7°C) throughout July.Heat index
The heat index value for July is estimated at a blazing hot 120.2°F (49°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.Research indicates the heat index considers values in shaded locales and with light winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
