Weather in September
Temperature
September's arrival comes with a mild decrease in the average high-temperature, moving subtly from 94.8°F (34.9°C) in August to a still hot 88.7°F (31.5°C). Throughout the month of September, De Berry observes an average nighttime temperature of 67.5°F (19.7°C).Heat index
September's mean heat index is calculated to be a very hot 102.2°F (39°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Heat index's context suggests values are appropriate for shady areas and slight breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for 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.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
