Weather in August
Temperature
The average high-temperature is a warm 85.6°F (29.8°C) in August, hardly different from the 87.1°F (30.6°C) recorded in July. Martha's nights in August are distinguished by a pronounced temperature shift from the day, with an average low of 62.4°F (16.9°C).Heat index
For most parts of August, the heat index is evaluated at a torrid 96.8°F (36°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
