Weather in July
Temperature
The warmest time of the year is July, with temperatures averaging a high of 83.5°F (28.6°C) and a low of 66°F (18.9°C).Heat index
For most parts of July, the heat index is computed to be a hot 93.2°F (34°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital 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.
