Weather in July
Temperature
July, known for its average high temperature of 81.1°F (27.3°C) and an average low temperature of 64.2°F (17.9°C), is the warmest month.Heat index
The heat index value during July is estimated at a tropical 87.8°F (31°C). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
