Weather in August
Temperature
August's advent denotes a minor fluctuation in the average high-temperature to a still hot 88.3°F (31.3°C) from July's 90.9°F (32.7°C). Throughout the month of August, the average temperature dips to a pleasant 68.5°F (20.3°C) at night.Heat index
Throughout August, the heat index is computed to be a sweltering 102.2°F (39°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Remember that heat index calculations are made for conditions in the shade with 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 'feels like' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. 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 hold particular significance 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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
