September weather forecast
Trat, Thailand

As September arrives, the rainfall decreases remarkably to 671mm (26.42"), a direct effect of diminished monsoon impact. The humidity continues to linger, creating a typical post-monsoon ambience. This period marks the gradual departure from monsoon to drier weather conditions. While the monsoon retreats, it leaves behind a latent humidity that translates into a distinctive climate. September, thereby, sets the course for the journey from an unpredictable weather towards a more stable climate.

Temperature

The commencement of September in Trat, Thailand, notes an average high-temperature of a still hot 30.9°C (87.6°F), exhibiting little difference from the previous month. The temperature in Trat dips to an average of 23.8°C (74.8°F) during September nights.

Heat index

In September, the average heat index is appraised at a blistering 43°C (109.4°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
