Weather in July
Temperature
Hannibal's warmest month, July, generally records average temperatures ranging from a high of 84.7°F (29.3°C) to a low of 67.1°F (19.5°C).Heat index
The heat index in July is calculated to be a torrid 96.8°F (36°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', quantifies the warmth felt when relative humidity is considered. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
