Isle of Man Weather in September

With autumn creeping in but the residual summer heat remaining, the Isle of Man is a time when temperatures are extremely comfortable on the island. With lower temperatures than the height of summer, daily averages of between 14–18°C bring a mildness to the island that is great for outdoor exploration including hiking and cycling. However, there are still plenty of hot and sunny days when temperatures peak into the 20s allowing you to enjoy beach days on the island too. 

Most days are clear and sunny providing a stunning backdrop for the incoming autumnal colours to contrast against. There are also some overcast days but they are typically few and far between. The month is also relatively dry with less than moderate rainfall. Showers are always a possibility but usually short, yet it is still best to be prepared and always head out with waterproofs. 

September also sees plenty of daylight with up to 12 hours of exploration time. With sunrise between 6:30-7:00am, you can still head out early to make the most of the day. At the start of the month, the sun does not set until after 7:00pm, getting earlier as the month progresses. However, this timing provides you with the opportunity to make the most of the autumnal daylight before making way for evenings snuggled up in a cosy pub or heading to one of the island’s Dark Sky Sites for a spot of stargazing. 

With mild temperatures and beautiful conditions throughout September, this is a month when the weather is at its finest with crisp mornings, warm days and plenty of sunny skies.
