Weather in September
Temperature
The start of September involves a subtle temperature drop, shifting from a fiery hot 95.2°F (35.1°C) in August to a hot 86.9°F (30.5°C). In the month of September, Dublin experiences an average low-temperature of 68.9°F (20.5°C).Heat index
For most parts of September, the heat index is calculated to be a torrid 95°F (35°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Sunshine

The average daily maximum UV index in September is 6. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for average individuals.Note: The maximum UV index, 6 during September, leads to the following recommendations:
Deter overexposure. Protecting against the sun's effects is essential. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses. Be aware! The intensity of the Sun's UV radiation can be amplified nearly twice due to snow reflection.
