Weather in August
Temperature
Rockport's August weather, with an average high temperature of 88.3°F (31.3°C) and an average low temperature of 81.1°F (27.3°C), tends to be the warmest of the year.Heat index
For most parts of August, the heat index is calculated to be an extremely hot 104°F (40°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. 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 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Deflect overexposure. Sun protection is a necessity. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Be mindful! Sand and water reflections can up the Sun's UV exposure.
