Weather in July
Temperature
The highest temperatures are recorded in July, with averages reaching a high of 82°F (27.8°C) and a low of 60.8°F (16°C).Heat index
In July, the average heat index is evaluated at a hot 87.8°F (31°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
