Weather in July
Temperature
July's arrival brings a temperature shift, moving from a pleasant 71.8°F (22.1°C) in June to a moderately hot 83.5°F (28.6°C). July nights bring a significant cooling from the heat of the day, with averages of 52.5°F (11.4°C).Heat index
During July, the heat index is computed to be 84.2°F (29°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
