Weather in September
Temperature
August's transformation into September witnesses an average high-temperature of a warm 85.3°F (29.6°C), noting a minor change from the preceding month. An average low-temperature of 65.3°F (18.5°C) marks the month of September.Heat index
The heat index value during September is calculated to be a sweltering 95°F (35°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Consider that heat index readings are for situations in the shade and light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

However, keep in mind that shade structures may not provide full sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
