Weather in July
Temperature
July, on average, is the warmest month, registering a high temperature of 90.3°F (32.4°C) and a low of 71.2°F (21.8°C).Heat index
The heat index for July is evaluated at a blistering 107.6°F (42°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Heat index's context suggests values are appropriate for shady areas and slight breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
