September weather forecast
Umm Al Hassam, Bahrain

September signifies a significant break from the searing summer heat of Umm Al Hassam, with temperatures beginning to dip from 36.4°C (97.5°F) to 35.3°C (95.5°F). This trend heralds the gradual retreat of summer, paving the way for more temperate conditions. With the decrease in temperatures, the city experiences a slightly increased probability of rain, although these instances remain infrequent. The daylight hours begin to recede, setting the stage for shorter autumn days. As September gives way to October, Umm Al Hassam prepares for cooler weather conditions, with a further reduction in temperatures.

Temperature

Heat index

September's average heat index is calculated to be a burning hot 45°C (113°F). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.
In terms of the heat index, values are set with light wind and shade conditions in mind. 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 'feels like' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
