Weather in August
Temperature
The introduction of August sees an average high-temperature of a moderately hot 85.5°F (29.7°C), hardly deviating from July. In August, Cool Valley experiences an average nighttime temperature of 67.1°F (19.5°C).Heat index
The heat index in August is evaluated at a very hot 95°F (35°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. 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 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
