Weather in July
Temperature
July is the month that records the highest temperatures, with averages ranging from a high of 81.7°F (27.6°C) to a low of 63°F (17.2°C).Heat index
For July, the heat index is estimated at a hot 86°F (30°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.The standards for the heat index are set for locations in shade and under light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. 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.
