Weather in July
Temperature
July is the warmest month, with an average high-temperature of 86.9°F (30.5°C) and an average low-temperature of 62.8°F (17.1°C).Heat index
The heat index in July is estimated at a hot 87.8°F (31°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to 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.
