Weather in August
Temperature
With the onset of August, the average high-temperature registers at a still hot 90.7°F (32.6°C), subtly different from July's 91.4°F (33°C). Despite a significant daily temperature range, Lamar's temperature falls to a steady low-temperature average of 68.4°F (20.2°C) in August.Heat index
August's mean heat index is calculated to be an extremely hot 109.4°F (43°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.The heat index's values are generally associated with conditions in shade and light breezes. 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 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
