Weather in July
Temperature
With average high and low temperatures of 93.4°F (34.1°C) and 70.7°F (21.5°C) respectively, July is Rock Island's warmest month.Heat index
In July, the heat index is appraised at a blazing hot 116.6°F (47°C). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
