Weather in August

August sees a slight dip in temperature, but remains firmly in Selma's summer season. August tallies 3.54" (90mm) of rainfall, a slight increase from the previous month's amount. The combination of high temperatures, high humidity, and elevated UV index form a classic representation of a southern summer month. Cloud cover remains relatively constant from the previous months, providing minimal protection from the sun. Despite a slight drop in wind speeds, conditions remain largely similar to those witnessed in July.

Temperature

Selma's shift into August is marked by a subtle change to a still hot 91.8°F (33.2°C) from July's 92.1°F (33.4°C) in temperature. Selma observes an average nighttime low-temperature of 72°F (22.2°C) during the month of August.

Heat index

In August, the heat index is estimated at a life-threatening hot 114.8°F (46°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. A surge in relative humidity can disrupt the body's normal cooling function 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.
