Weather in August
Temperature
The start of August sees the average high-temperature at a still hot 91.9°F (33.3°C), showing little difference from July's 92.3°F (33.5°C). Calvert records an average nighttime low-temperature of 73.6°F (23.1°C) throughout August.Heat index
During August, the heat index is calculated to be a life-threatening hot 116.6°F (47°C). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.Consider that heat index readings are for situations in the shade and light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Take precautions against overexposure. Protection against sun damage is needed. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
