Weather in August
Temperature
The average high-temperature in August, at a still hot 86°F (30°C), reveals a modest deviation from July's 87.6°F (30.9°C). During the month of August, the temperature generally drops to a low average of 65.8°F (18.8°C).Heat index
August's mean heat index is computed to be a torrid 96.8°F (36°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.In terms of the heat index, values are set with light wind and shade conditions in mind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
