Weather in July
Temperature
July is the warmest month, with an average high-temperature of 85.8°F (29.9°C) and an average low-temperature of 64°F (17.8°C).Heat index
July's heat index is computed to be a very hot 95°F (35°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. 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', gives a temperature feeling by integrating air temperature and humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
