Weather in September
Temperature
Carnis observes a small decrease in the average high-temperature with the arrival of September, falling from August's hot 91.4°F (33°C) to a warm 84.4°F (29.1°C). A stark contrast in day to night temperatures can be seen in September, with an average low-temperature of 62.6°F (17°C).Heat index
September's heat index is computed to be a tropical 91.4°F (33°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
