Weather in July
Temperature
The beginning of July reveals an average high-temperature of a torrid 97°F (36.1°C), showing minimal deviation from the previous month. Throughout the month of July, O'Brien reports a steady low-temperature average of 77°F (25°C).Heat index
The heat index value for July is evaluated at a blisteringly hot 109.4°F (43°C). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.Consider that heat index readings are for situations in the shade and light wind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Always be careful, as unprotected skin and eyes might burn in no time. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
