Weather in July
Temperature
July, with its high-temperature average of 84.4°F (29.1°C) and a low-temperature average of 67.5°F (19.7°C), is the warmest month.Heat index
During July, the heat index is calculated to be a fiery hot 95°F (35°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
