Average Temperatures and Sunshine Hours

September in the UK sees a noticeable drop in average temperatures compared to August. While the south often enjoys daytime highs around 18-20°C (64-68°F), the north tends to be slightly cooler, with highs closer to 15-17°C (59-63°F). Nighttime temperatures can dip significantly, especially in the north and higher elevations, often falling to around 8-10°C (46-50°F) or even lower. These cooler evenings are a key characteristic of September weather.

Sunshine hours also decrease in September. While you can still expect a reasonable amount of sunshine, particularly in the south and east, the overall duration reduces compared to the summer months. Expect approximately 5-7 hours of sunshine per day on average, but this can vary greatly depending on location and specific days. Some days will be bright and sunny, while others might be overcast or even experience spells of rain. This variability is a significant factor to consider when planning outdoor activities.

Rainfall and Humidity

Rainfall in September is generally moderate across the UK. While it's not typically as wet as the autumn and winter months, expect some rain showers throughout the month. The west coast, particularly in regions like Scotland and Wales, usually experiences higher rainfall than the east coast. The exact amount of rainfall will depend on the year and specific location. It’s always wise to check the local forecast closer to your travel date.

Humidity levels remain relatively high throughout September, especially in coastal areas. This can contribute to a feeling of dampness even on days without rain. This higher humidity is another characteristic to bear in mind when choosing clothing and planning outdoor pursuits.
