September weather forecast
Ranong, Thailand

September rings in the closing stages of the wet season in Ranong. The rainfall average descends to 647mm (25.47"), signalling a gradual retreat from the peak reached in the previous month. This fall in rainfall is coupled with a minor dip in temperature, providing much-needed relief from the monsoon extremities. Despite the slowly subsiding rains, humidity levels remain high, creating a balmy climate. Therefore, September masterfully orchestrates the segue from heavy rains to drier days.

Temperature

Ranong's coldest season falls during August and September, averaging a high-temperature of 30.5°C (86.9°F).

Heat index

During September, the heat index is evaluated at a blisteringly hot 41°C (105.8°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Humidity

August and September, with an average relative humidity of 86%, are the most humid months.
