Weather in July

The warmest period is July, when temperatures fluctuate between an average high of 80.6°F (27°C) and a low of 70.9°F (21.6°C).Heat index
July's heat index is computed to be 84.2°F (29°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for 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.
