Weather in July
Temperature
With average high temperatures of 94.6°F (34.8°C) and lows of 60.4°F (15.8°C), July is the warmest month.Heat index
For most parts of July, the heat index is evaluated at a very hot 100.4°F (38°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
