Weather in August
Temperature
August's arrival brings an average high-temperature of a moderately hot 84.4°F (29.1°C), slightly deviating from July's 86°F (30°C). Nightly temperatures drop to an average low of 66°F (18.9°C) in August.Heat index
The average heat index in August is estimated at a torrid 95°F (35°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Note that heat index values are valued for light wind and location in the shade. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
