Weather in August
Temperature
Marston's transition from July to August introduces an average high-temperature of a still hot 86.4°F (30.2°C), marking an insignificant variation from the 87.6°F (30.9°C). Marston observes an average nighttime low-temperature of 67.8°F (19.9°C) during the month of August.Heat index
During August, the heat index is appraised at a very hot 98.6°F (37°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
