Weather in August
Temperature
Shirley's August average high-temperature settles at a still moderately hot 84.7°F (29.3°C), showing a near match with the preceding month. During the month of August, an average temperature of 63.3°F (17.4°C) is noted during the nights.Heat index
August's mean heat index is estimated at a sweltering 95°F (35°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
