Weather in September
Temperature
September's average high-temperature is a moderately hot 85.5°F (29.7°C), maintaining a close comparison with August's 88.9°F (31.6°C). Dublin's average low-temperature in the month of September is recorded at an enjoyable 66.9°F (19.4°C).Heat index
During September, the heat index is estimated at a fiery hot 95°F (35°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
