Weather in July
Temperature
July, having an average high-temperature of 83.8°F (28.8°C) and an average low-temperature of 55.2°F (12.9°C), is the warmest month.Heat index
The heat index value during July is computed to be a tropical 86°F (30°C). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception 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 especially vital to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
