Weather in September
Temperature
Montegut registers an average high-temperature of a still hot 86.4°F (30.2°C) at the commencement of September, closely related to the preceding month. Montegut in September anticipates an average nighttime temperature of 74.3°F (23.5°C).Heat index
For most parts of September, the heat index is computed to be a very hot 98.6°F (37°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection.
