Weather in July
Temperature
July, with its average high-temperature of 81.9°F (27.7°C) and an average low-temperature of 62.2°F (16.8°C), holds the record as the warmest month.Heat index
The heat index in July is computed to be a tropical 87.8°F (31°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. 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 relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
