Weather in July
Temperature
July tends to be the warmest month, with temperatures averaging a daily high of 81.1°F (27.3°C) and a low of 63.9°F (17.7°C).Heat index
July's mean heat index is calculated to be a tropical 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
