The climate of the Normandy region of France during September offers a transition from summer to autumn. Typically, visitors can expect mild temperatures, ranging from daily highs around 18-20C (mid-60sF) to overnight lows around 10-12C (low 50sF). Rainfall is moderate, interspersed with periods of sunshine. This period experiences decreasing daylight hours as the season progresses.
This time of year presents several advantages for travelers. The summer crowds have generally thinned, allowing for a more relaxed experience at popular attractions. Accommodation rates may also be lower compared to the peak summer months. The pleasant weather is often conducive to outdoor activities such as hiking and cycling, while the changing foliage begins to display the early hues of autumn. Historically, September marks the end of the main tourist season and a return to a more tranquil pace of life in the region.
