Weather in July
Temperature
July is the warmest month of the year, registering average temperatures as high as 81.3°F (27.4°C) and as low as 64.6°F (18.1°C).Heat index
During July, the heat index is evaluated at a hot 87.8°F (31°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.For clarity, heat index numbers account for light winds and areas under shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
