Weather in July
Temperature
July is the warmest month, with the temperature often reaching an average high of 85.3°F (29.6°C) and an average low of 67.6°F (19.8°C).Heat index
The heat index for July is evaluated at a sweltering 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
