Weather in July
Temperature
With its high average temperature of 81.9°F (27.7°C) and a low of 64.6°F (18.1°C), July is regarded as the warmest month.Heat index
The average heat index in July is estimated at a tropical 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
