Weather in July
Temperature
July is the warmest month, with the temperature often reaching an average high of 81.1°F (27.3°C) and an average low of 66.4°F (19.1°C).Heat index
Throughout July, the heat index is evaluated at a hot 86°F (30°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
