September deserves to be a more popular time to visit Iceland. Though youâll miss out on seeing the sun high in the sky well past 10pm (sunset is around 7:30pm and the sun rises around 6:30am), temperatures are still quite nice, with average temps between 10.1Â°C (50 Â°F) and 5Â°C (41 Â°F) throughout the month, and prices are lower and crowds are fewer.
September is slightly cooler than previous months but is still fairly warm. The average temperature still reaches a high of 22C (that's about 72F) during the day and dips to a fairly mild 13C (about 55F) in the evenings. You can still expect rain on an average of 9 days of the month.
