Weather in August
Temperature
The warmest period, with an average high-temperature of 81.7°F (27.6°C), falls in August and September.Heat index
The heat index value for August is computed to be a hot 86°F (30°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. 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 highly important 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.
