Temperature
Mareth's progression into September involves a gentle drop in the average high-temperature, from a very hot 35°C (95°F) in August to a tropical 32°C (89.6°F). Throughout September, the temperature falls to an average low of 23.1°C (73.6°F).Heat index
For most parts of September, the heat index is calculated to be a hot 34°C (93.2°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
