September weather forecast
Loei, Thailand

September marks a slow transition from rainfall-laden months towards the drier years' end. While the city still receives plenty of rain, the volume reduces to 204mm (8.03"), a respite from August's highest. Diminishing rainfall aligns well with the gradually dropping temperature, making it a month of atmospheric adjustments. The duration of daylight remains consistent, and the differential between day and night temperatures starts to fall. As such, the city garners a sense of emergence from heavy rains towards more stable weather.

Take into consideration that the heat index values are calculated for shade and light wind conditions. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
