Weather in August
Temperature
On the advent of August, Grays's average high-temperature exhibits a minor adjustment to a still moderately hot 84.6°F (29.2°C) from July's 84.9°F (29.4°C). Despite substantial daily fluctuations, the average low-temperature is a mild 60.6°F (15.9°C) during August.Heat index
The heat index value during August is evaluated at a hot 93.2°F (34°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Heat index data is primarily for areas with shade and subjected to light winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are quite important 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.
