Weather in July
Temperature
With average temperatures fluctuating between a high of 86.7°F (30.4°C) and a low of 68.9°F (20.5°C), July stands out as the warmest month.Heat index
The heat index in July is estimated at a torrid 100.4°F (38°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
