Weather in July
Temperature
Port Arthur, Texas, experiences a recorded average high-temperature of a still hot 90.7°F (32.6°C) in July, closely aligned with June's 88.9°F (31.6°C). In Port Arthur, July nights cool down to an average of 78.4°F (25.8°C).Heat index
The heat index in July is calculated to be a scorching 111.2°F (44°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
