Weather in July
Temperature
July, with its high-temperature average of 80.6°F (27°C) and a low-temperature average of 64°F (17.8°C), is the warmest month.Heat index
For most parts of July, the heat index is calculated to be a tropical 86°F (30°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
